**** BEGIN LOGGING AT Thu Nov 21 02:59:59 2013 Nov 21 03:00:49 I can't use the web without my parents here, so maybe we could talk about the points, eh? Nov 21 03:02:34 What's Cloud9 IDE? Nov 21 03:04:18 Does the beaglebone black have an IDE on it? Nov 21 03:04:28 Hello! Nov 21 03:06:27 what's an IDE? Nov 21 03:06:55 No, is Cloud9 IDE for beaglebone black! Nov 21 03:07:20 what is an IDE? Nov 21 03:07:48 vim Nov 21 03:07:51 integrated development environment, right? Nov 21 03:08:18 what does IDE on it mean? Nov 21 03:08:47 can you write programs directly on the beaglebone black? Nov 21 03:09:05 can you? Nov 21 03:09:40 I don't know, i'm asking you? Nov 21 03:09:54 I probably could, but I'm not sure how legible it'd be Nov 21 03:10:11 they're not very flat, lots of bumps Nov 21 03:10:24 hello friends Nov 21 03:10:37 Which is easier, arduino or beaglebone black? Nov 21 03:10:44 Hello, frege! Nov 21 03:10:58 what are you guys up to? Nov 21 03:11:11 arduino is going to have way more helpful documentation available. BBB is much more powerful Nov 21 03:11:40 do you really need docs for BBB? Nov 21 03:11:59 So should I get an arduino or BBB? Nov 21 03:12:08 wathctgry: what do you want to do? Nov 21 03:12:09 wathctgry: I'd get better internet Nov 21 03:12:31 i would suggest lego mindstorms Nov 21 03:12:41 are you guys trolling him? Nov 21 03:12:49 What do you mean by "get better internet" Nov 21 03:12:51 the opposite Nov 21 03:13:05 wathctgry: are you trolling us? Nov 21 03:13:08 * TehCaptain isn't trolling anyone Nov 21 03:13:21 who is trolling? Nov 21 03:13:25 What's going on! Nov 21 03:13:34 wathctgry: what do you want to do? Nov 21 03:13:34 Who's trolling who! Nov 21 03:13:53 * TehCaptain cracks a 24 ounce beer Nov 21 03:14:06 wathctgry: I have both Arduino and beagleboard black Nov 21 03:14:37 whenever I tried to help; I realized that I'm wasting my time :( Nov 21 03:14:45 I just want to get a powerful easy to use board, cause arduino is SSSLLLOOOWWW! Nov 21 03:15:01 arduino is faster than me Nov 21 03:15:10 I'm listening, frege! Nov 21 03:15:16 wathctgry: what's what noobs say... Nov 21 03:15:16 I can't perform 16,000,000 operations per second Nov 21 03:15:18 it's slow Nov 21 03:15:20 thews, it better be! Nov 21 03:15:39 wathctgry: are you a programmer? Nov 21 03:15:45 I tried to run a display on it and WOWWOWOWOWOWO! Nov 21 03:15:54 It was slower than mutts! Nov 21 03:16:08 my cat is pretty fast Nov 21 03:16:11 Oh, yeh! But a beginner! Nov 21 03:16:37 TehCaptain: arduino makes my cats faster Nov 21 03:16:58 ok learn to program faster; and read about "Hundredth monkey effect" Nov 21 03:17:18 one day you will write a code that's fast enough that satisfies your desire for speed Nov 21 03:17:28 What's going on, again! Did I miss something! Nov 21 03:18:15 The arduino is slow, not me. Nov 21 03:18:51 I got the very question, do you know of a intelligent display other than 4D, frege? Nov 21 03:19:26 Hey, thews, have you heard of mbed! Nov 21 03:19:38 wathctgry: there are some basic principles in CS. very general. speed is relative. you can't use a hammer as a screw driver. Nov 21 03:19:47 different things were made for different purposes Nov 21 03:20:02 it's like me saying why doesn't sky shit on my head? Nov 21 03:20:29 So your saying that arduino is for one thing and BBB is for an other? Nov 21 03:20:49 there's nothing intelligent about computers Nov 21 03:20:56 or peripherals Nov 21 03:21:07 I thought I'm the best troll on freenode; this guys just trolled me like a champ Nov 21 03:21:13 wathctgry: nice! Nov 21 03:21:51 you mean I keep asking questions, that's what trolling is? Mmmm.... Nov 21 03:22:46 do you know of a intelligent display other than 4D, frege? Nov 21 03:23:26 wathctgry: do you live in Alberta? Nov 21 03:23:55 wathctgry: around Peace River? Nov 21 03:24:04 Yes! But that's not an intelligent display I was looking for! Nov 21 03:24:10 LOL Nov 21 03:24:21 wathctgry: well, I'm coming after you buddy Nov 21 03:24:33 For what! Nov 21 03:24:58 Cause I ask you question like a school boy! Nov 21 03:25:03 to give you a more intelligent LCD Nov 21 03:25:23 LOL Nov 21 03:25:57 So...do you know of a intelligent display other than 4D, frege? Nov 21 03:26:09 I know something that doesn't display intelligent Nov 21 03:26:33 I found SmartGPU 2 from vizic technologies Nov 21 03:26:48 thews, I'm talking to frege! Nov 21 03:27:03 wathctgry: I think you're talking to the channel Nov 21 03:27:34 where did frege go? Nov 21 03:27:34 wathctgry: you are talking to the channel. otherwise you were talking to me in pm which I don't allow it Nov 21 03:28:27 I can't ssh to my BBB Nov 21 03:28:37 it makes me nervous Nov 21 03:28:45 I could do it last time I turned it on Nov 21 03:28:46 Ok, I came here for info not to talk about the weather, which it was -35 this morning here, Nov 21 03:29:19 everything is info Nov 21 03:29:28 So, you don't know of any other intelligent displays, eh? Nov 21 03:29:58 wathctgry: no I don't Nov 21 03:30:10 I froze my ears off when working outside this morning! (-35 is cold!) Nov 21 03:30:32 nice after a reset my ssh is back Nov 21 03:30:38 Thanks, frege, for you assistance! Greatly appreciated! Nov 21 03:30:48 I didn't assist you Nov 21 03:30:53 what is a ssh! Nov 21 03:31:10 how did you get to IRC? Nov 21 03:31:10 Yes, you talk about what I want to hear! Nov 21 03:31:17 ssh! Nov 21 03:31:25 no a better question. how did you turn on your computer? Nov 21 03:31:51 wathctgry: how old are you? Nov 21 03:32:05 I found it at beagleboard.org and I turned on my computer by pressing the power button! Nov 21 03:32:25 How old are you first, frege? Nov 21 03:32:27 wathctgry: oh I see; sorry friend I had too much expectation Nov 21 03:32:49 just a misunderstanding; there used to be a time that everyone was a hacker on irc Nov 21 03:33:24 wathctgry: thanks for the intelligent display Nov 21 03:33:28 wathctgry: ssh is a way to communicate and run commands over network remotely on another computer Nov 21 03:33:32 it's a protocol Nov 21 03:33:37 No, I'm no hacker, as I can't even program a BBB! Nov 21 03:33:54 take it easy nobody suggested that you are a hacker Nov 21 03:33:54 Are you trying to get on my computer? Nov 21 03:34:01 oh fuck Nov 21 03:34:13 why can't I just ignore this guy :( Nov 21 03:34:21 Bye Nov 21 03:34:25 frege: turn the questions around Nov 21 03:34:53 thews: I can't!!!! it's like playing chess with a cow Nov 21 03:35:07 sorry I shouldn't say that Nov 21 03:35:08 frege: I don't find myself in that situation Nov 21 03:35:26 lets forget that and get back to the topic Nov 21 03:35:58 topic is American Horror Story is about to be on Nov 21 03:36:00 :) Nov 21 03:36:15 you know what; ppl put irc channels on their websites and with this webchat shit it's easy for kids to get into irc without knowing about shit Nov 21 03:36:21 lots of long days and too much responsibility means it's time to shut my brain down Nov 21 03:36:24 then you will get conflicts here Nov 21 03:36:34 well that was pretty obvious trolling Nov 21 03:36:53 might need to make the channel where only registered nicks can talk Nov 21 03:36:56 I suggested putting a more difficult captcha on webchat to filter out these kids but nobody listened Nov 21 03:37:08 yeah I like that!!!! Nov 21 03:37:11 I think he could have passed some of it Nov 21 03:37:17 thews: who is the op here? Nov 21 03:37:37 av500, jkridner and prpplague Nov 21 03:37:48 jkridner might be the owner Nov 21 03:37:57 yeah Nov 21 03:38:01 he is Nov 21 03:38:02 ^^^ hey guys, is there a reason that everyone can get in and talk about anything? Nov 21 03:38:17 can't you limit it to registered users on freenode? Nov 21 03:38:54 but they wanna promote BBB so I guess theyy don't wanna limit the audience or ppl who get support Nov 21 03:39:01 but it fucks up the community Nov 21 03:40:21 * mranostay cracks open a beer Nov 21 03:40:27 * mranostay opens his lawn chair Nov 21 03:40:39 * mdp hands mranostay some jiffy pop Nov 21 03:41:54 how do you guys drink beer? Nov 21 03:42:02 I can't do that Nov 21 03:43:36 like i drink water only this is much tastier Nov 21 03:44:01 it's volunteerly intoxication of your brain Nov 21 03:44:26 ah your point is sir? :) Nov 21 03:44:28 you will lose neuroplasticity in your brain as you drink that Nov 21 03:44:55 just asking; I used to drink myself but I didn't know what it does to my head Nov 21 03:45:07 ok mom :) Nov 21 03:45:08 and a lot of engineers drink Nov 21 03:45:17 don't they know it or just ignore it? Nov 21 03:45:43 I'm just asking... :( Nov 21 03:47:30 oh shit I gave that kid the wrong theorem related to mokeys Nov 21 03:47:35 I meant this one http://en.wikipedia.org/wiki/Infinite_monkey_theorem Nov 21 03:49:06 back to BBB Nov 21 03:49:15 so guys I have this simple infrared sensor Nov 21 03:49:24 working fine Nov 21 03:49:35 but I want to improve it Nov 21 03:50:07 and turn it to a proper signal Nov 21 03:50:12 right now I just read 0 and 1 Nov 21 03:50:28 is there any practical code possibly in C or python for that Nov 21 04:00:40 frege: I can't drink much / often either Nov 21 04:01:14 I get alcohol flush too though, which puts you at much higher risk of throat cancer if you do drink Nov 21 04:01:29 but I don't like anything that makes me lose my mental edge Nov 21 04:01:36 yeah Nov 21 04:01:57 I feel shitty; like why the fuck am I doing it to myself Nov 21 04:01:58 I have bad concentration problems as is, although most people would argue that I don't, because they're not interested in the things I want to concentrate on Nov 21 04:02:35 frege: http://en.wikipedia.org/wiki/Alcohol_flush_reaction Nov 21 04:03:00 I know what it is Nov 21 04:03:04 I don't have it Nov 21 04:03:28 I didn't realize it was a bad thing until a few years ago Nov 21 04:03:40 when I was a teenager drinking didn't bother me Nov 21 04:03:53 but entering my 20s it got worse and worse Nov 21 04:04:29 yeah same for me; but mostly intellectually and just realizing how stupid and harmful it is Nov 21 04:04:46 too bad that it isn't banned Nov 21 04:05:01 education is the best control Nov 21 04:05:03 advertisement for smoking is being prohibited Nov 21 04:05:10 but not for alcohol Nov 21 04:06:00 I tried weed in my teens too, and even then it fogged my brain for weeks Nov 21 04:06:10 there's no way I could stay sharp on mind altering stuff Nov 21 04:07:09 * mranostay sips beer reads backlog Nov 21 04:24:14 guys I fixed this last time but I have the same exact problem Nov 21 04:24:29 in my IR circuit I got a pullup resistor Nov 21 04:24:38 +2kohm Nov 21 04:24:48 with a protective one that' 300ohm Nov 21 04:24:56 now I get a constant 1 all the time Nov 21 04:25:03 protective one? Nov 21 04:25:19 shouldn't need more than one Nov 21 04:25:31 sorry not protective Nov 21 04:25:39 on the side of input Nov 21 04:25:56 in series with the sensor ? Nov 21 04:26:05 protective one? Nov 21 04:26:06 yeah Nov 21 04:26:11 probably don't need that Nov 21 04:26:17 you for sure don't Nov 21 04:26:17 could be throwing it off Nov 21 04:26:23 yes Nov 21 04:26:48 depending on the current Nov 21 04:26:54 you're basically making the resistance less on the pullup, so that's what it always does Nov 21 04:27:10 let me redo it Nov 21 04:27:17 I will sketch it somewhere in a sec Nov 21 04:27:39 the idea of a pull up or pull down is to make a path of less resistance if whatever else isn't closing the circuit Nov 21 04:28:23 now in rare cases, like a capacitance sensor, you would have more than one resistor Nov 21 04:29:15 gotcha; it's not that case here Nov 21 04:29:38 because then whenever something touches the material that is holding the capacitance it needs to trigger it to pull one way or the other, and the resistance of that medium needs to be dialed in Nov 21 04:33:41 thews: should the shorter leg be on the side of power or input? Nov 21 04:33:44 for the photodiode Nov 21 04:34:00 short leg is supposed to always go to ground Nov 21 04:36:10 thews: ground or 3 v power? Nov 21 04:36:25 depends on what sensor you are using Nov 21 04:36:28 let me find an example Nov 21 04:37:25 thews: http://flockdraw.com/cvumwa mind? Nov 21 04:37:46 thews: infrared range 400nm to 1100nm Nov 21 04:39:33 frege: to me I'd think you would put the short leg to ground, and the positive to the pin, and you would use a resistor that pulled it to 3.3v if it had less resistance than whatever was causing it to fall below that threshold Nov 21 04:41:16 some of the IR sensors I see have 3 pin http://fritzing.org/projects/infrared-experiments-with-arduino Nov 21 04:41:49 you may want to use a potentiometer in place of the resistor and dial it Nov 21 04:42:11 thews: that used to be the way I was doing it Nov 21 04:42:28 thews: mine has 2 Nov 21 04:42:34 if you can measure the values on the pot with a multimeter you can find a resistor in the range you need Nov 21 04:42:50 I don't have a multimeter :( Nov 21 04:42:57 I would keep outputting the result over and over Nov 21 04:42:57 ahh Nov 21 04:43:06 I really need one Nov 21 04:43:09 what do you recommend? Nov 21 04:43:24 you could "make one" using the analog ports and voltage dividers, but that isn't very simple Nov 21 04:43:43 if you are pretty serious about wanting to work on or repair electronics for the rest of your life Nov 21 04:44:12 http://www.amazon.com/Extech-EX505-K-Heavy-Industrial-MultiMeter/dp/B004CR4M5Q Nov 21 04:44:13 thews: I will have to learn electronics at least the basics Nov 21 04:44:35 frege: that multimeter has almost all good features, and is very reliable and super rugged Nov 21 04:44:39 and easy to use as a bench multimeter Nov 21 04:44:59 it's a tiny bit slower than a 3 times higher priced fluke multimeter, but just as useful Nov 21 04:45:19 there are cheap multimeters that can tell you resistance well enough though, probably less than 20 bucks on ebay Nov 21 04:45:41 but if you want to test capacitance (verify your capacitors), have auto ranging, and read true RMS Nov 21 04:45:46 you can't beat that multimeter kit Nov 21 04:46:11 have to run Nov 21 04:46:26 nice Nov 21 04:48:03 thews: I think I will actually need one with that percision Nov 21 04:48:28 it was a very worthwhile investment for me Nov 21 04:48:57 thews: is it your job or just hobby? Nov 21 04:49:17 I also got some IC hooks on sale from radioshack, and some small alligator clips from ebay or amazon Nov 21 04:49:29 frege: my hobby, but somewhat connected to my job Nov 21 04:50:24 I'm a systems engineer, and sometimes I make gadgets that connect to systems for alarms or gauges Nov 21 04:51:02 oh cool! Nov 21 04:51:04 I experiment with things that increase productivity in workers Nov 21 04:51:05 !!!! Nov 21 04:51:14 very cool Nov 21 04:51:48 wife has a show on now, have to run :) Nov 21 04:51:50 have a good night Nov 21 04:52:01 gnight thews Nov 21 06:22:51 im trying to get a usb dac (pcm2704) working on a fresh install of debian wheey. I thought I need to modprobe something, but i see no modules in /etc/modules at all. Can anyone point me the right direction? Nov 21 09:02:30 Hi everyone! Nov 21 09:02:43 Is someone out there listening? Nov 21 09:03:16 I have a simple question. Nov 21 09:03:45 I made a simple "cape" for the BeableBone Black. Nov 21 09:04:38 It basically has some level shifters. Nov 21 09:05:00 just ask, and if someone knows, you will get an answer. so far, you have not asked anything. Nov 21 09:05:20 Now I'm trying the cape for the first time and the Beagle doesnt seem to be booting. Nov 21 09:05:30 I've tried pressing both reset and power buttons. Nov 21 09:05:56 I've only managed to turn it on by putting the microSD in it. Nov 21 09:07:21 Is there some consideration regarding the expansion headers by which I'm not supposed to connect some pins during power on?? Nov 21 09:08:07 When I take out my cape, the Beagle boots just fine. Nov 21 09:08:42 When the cape is plugged, the power led turns on and nothing else happens. Nov 21 09:08:58 so first, check your power rails, and if you are maybe using some pin that is already occupied otherwise. Nov 21 09:09:24 jvelazaueztraut, check to see if you are mucking with the sysboot pins Nov 21 09:10:03 which one are the sysboot pins?? are they exposed in the headers? Nov 21 09:11:20 "everything goes black" sounds more like killing a power rail to me. shorting it, drawing too much, etc. pp. Nov 21 09:11:54 ok, i've just found the sys boot pins in the RM. Nov 21 09:12:20 gonna check that out and shout out if i'm having trouble figuring it out. Nov 21 09:12:24 thanks. Nov 21 09:18:31 Hello, does anybody here know who wrote this? http://elinux.org/BeagleBone_Black_Extracting_eMMC_contents Nov 21 09:18:48 http://elinux.org/index.php?title=BeagleBone_Black_Extracting_eMMC_contents&action=history Nov 21 09:19:02 some jkridner dude Nov 21 09:19:02 aha ty Nov 21 09:19:17 he was on here a while ago Nov 21 09:19:22 and helped me with it Nov 21 09:19:37 i'm writing something and wanted to give credit to him is all Nov 21 09:23:09 thanks for the help @Russ, I was using some system boot pins indeed. Nov 21 09:23:32 as long as you wait until after initial power on reset to drive them, you are fine Nov 21 09:23:57 av500: I broke my sub/amp trying to fix it, what brand should I check for a replacement ? Nov 21 09:24:57 ? Nov 21 09:25:15 it was my understanding you knew a whole lot about amplifiers ? Nov 21 09:25:33 and had a borderline fascination for tubes Nov 21 09:25:54 ah Nov 21 09:26:06 so a powered sub? Nov 21 09:27:35 it was a powered sub/amp G51 from logitech for my computer, was told I should ditch it all since all speakers are tightly coupled together Nov 21 09:28:07 ugly Nov 21 09:28:29 Hi Nov 21 09:29:04 I guess stuff in that price range is all more or less the same quality Nov 21 09:29:11 3kg of plastic down the drain for one IC burnt ... Nov 21 09:29:36 av500: I'm willing to pitch in a little more this time, maybe 300E ? Nov 21 09:30:33 but next time there's a problem I want to be able to fix it Nov 21 09:30:57 well Nov 21 09:31:07 so you want one with schematics? Nov 21 09:31:09 and easy to buy parts? Nov 21 09:31:13 and a service manual? Nov 21 09:31:18 build a generic amplifier pcb, some speaker and some wood :) Nov 21 09:31:40 thats an option Nov 21 09:31:50 you can also get some 2.1 amp from china Nov 21 09:32:23 got some brand names I should check out ? Nov 21 09:32:39 I could build one too, that's true Nov 21 09:32:42 http://www.aliexpress.com/item/Freeshipping-Wholesale-Retail-DIY-AMP-2-1-Channel-TDA7294-2x80W-160W-Subwoofer-Multimedia-Amplifier-Board/816688862.html Nov 21 09:32:47 http://www.aliexpress.com/item/200W-Single-bus-12V-HiFi-High-Power-Subwoofer-Amplifier-for-Toshiba-C5198-A1941/707738157.html Nov 21 09:33:03 http://www.amazon.de/Teufel-Consono-5-1-Set-Heimkino-Lautsprecher-Set-preisbewusste/dp/B00AES1P48/ref=sr_1_1?s=ce-de&ie=UTF8&qid=1385026239&sr=1-1&keywords=Teufel Nov 21 09:33:08 teufel should be quite ok Nov 21 09:33:21 I have a large teufel sub and satellites Nov 21 09:33:34 powered sub Nov 21 09:34:20 saving the links for tonight, thanks Nov 21 09:37:23 http://sound.westhost.com/p-list.htm Nov 21 09:40:56 das: ^^^ lot of projects if you really want to build and learn Nov 21 09:41:34 av500: yeah I'm currently frantically clicking these links, it looks awesome thanks a lot Nov 21 09:44:02 cant tell you about the quality of the china stuff, but its cheap Nov 21 09:44:29 as long as they use modules like the TDA7294 and follow the sample schematic it should be ok Nov 21 09:44:52 I would stay away from the max power, but you dont need 160W anyway Nov 21 09:45:00 and always good cooling Nov 21 09:45:13 das: take a week to read the westhost site Nov 21 09:45:21 hi! Nov 21 09:45:23 its highly informational and entertaining :) Nov 21 09:45:41 yeah but the shipping time is redhibitory, I'll probably get the Teufel and build my own stuff from scratch in the same time, money's not really an issue if I learn stuff Nov 21 09:45:49 thanks for the advice ! Nov 21 09:46:17 yeah, shipping is a pain Nov 21 09:46:53 Hi, there is a way to run bonescript for non root users? Nov 21 09:46:57 when building, buy a good speaker with high efficiency Nov 21 09:47:09 but westhost explains that all to you :) Nov 21 09:47:46 yeah I'm taking the day off tomorrow so I can read as much as possible in the 3 next days, this site looks awesome Nov 21 09:48:45 I wish I had it 20 ys ago :) Nov 21 09:49:21 so it's that good haha Nov 21 09:49:50 there is also a nice pdf, sec Nov 21 09:52:15 cant find it now, must be on the laptop at home Nov 21 09:52:44 shall I remind you of it tonight ? Nov 21 09:53:25 H.264 is quite the complicated codec Nov 21 09:54:06 and from I understand, quite a bit of "choose your own adventure" action Nov 21 09:55:52 somesomething: you already started implementing it? Nov 21 09:56:57 It's quite magical Nov 21 09:57:14 more like a short literature study so far Nov 21 10:09:10 (actually I have no experience with any video related programming) Nov 21 10:10:05 good Nov 21 10:10:20 so you are not hindered be prejudice Nov 21 10:11:16 or any real programming on that. Nov 21 10:13:33 somesomething, if you want to start smaller, I suggest something like this: http://graphics.stanford.edu/projects/texture/ Nov 21 10:14:38 I used to know a bit about h264 encoding Nov 21 10:15:11 what is beagle? Nov 21 10:15:14 I only know the dog Nov 21 10:15:45 There is a way to get all pin mux in angstrom linux on bb black? Nov 21 10:23:17 http://beagleboard.org Nov 21 10:56:22 The omap_mux folder is missing on kernel 3.8? Nov 21 11:04:46 yes Nov 21 11:04:53 its DT all the way now Nov 21 11:07:56 good av500 and there is a way to view current pin mux? Nov 21 11:08:06 yes Nov 21 11:08:10 somewhere in sysfs Nov 21 11:08:30 http://elinux.org/BeagleBone_and_the_3.8_Kernel Nov 21 11:08:33 read this first Nov 21 11:13:18 thanks! Nov 21 11:40:13 hi Nov 21 11:42:22 anybody could help me to install a Realtek WIFI dongle with BBB A5 and debian wheezy?? I can't install ;( Nov 21 11:49:33 AnyBody installed a WIFI dongl on Beagle Bone Black?? Nov 21 11:50:09 I think there are some blog posts describing this Nov 21 11:50:18 it's mostly just making sure the firmware is installed Nov 21 11:51:36 dm8tbr: my dongle is a realtek i installed the firmware from aptitude and configue network interface but the wlan0 don't show on interfaces Nov 21 11:53:40 script is some damn handy stuff Nov 21 11:55:34 masalinas: so you're not running angstrom? Nov 21 12:47:19 dm8tbr: I run Debian 7.0 Nov 21 13:00:40 masalinas: well, make sure the realtek kernel module and firmware are there Nov 21 13:08:11 reading about usb and just wondering how many usb devices out there really respect the usb specs and limit themselves to 100 mA on usb bus connect Nov 21 13:08:22 few Nov 21 13:08:29 we did Nov 21 13:09:36 av500: what type of devices are you doing? I think this only possible for harddrives etc Nov 21 13:09:47 android devices Nov 21 13:10:32 interesting, although android is not a device type :) Nov 21 13:12:10 ? Nov 21 13:12:19 what does it have to do with device type? Nov 21 13:13:48 MAGIC Nov 21 13:14:39 I mean e.g. on a harddrive you can make sure that it does not spin up until it is allowed to use 500 mA but this is not possible for boards that always require the 500 mA Nov 21 13:14:59 those then don't comply with the USB spec Nov 21 13:15:26 fuck specs Nov 21 13:15:35 right, but most manufacturers probably don't really care Nov 21 13:17:44 usb is shit anyway Nov 21 13:18:09 but what is an alternative? Nov 21 13:18:31 an universal parallel bus ? Nov 21 13:21:06 dbus Nov 21 13:22:23 i need a firewire cape on my BBB :) Nov 21 13:22:24 as long as you make it a standard and then integrate it in a monster with no way back, I'm in ! Nov 21 13:22:40 FW is dead, no? Nov 21 13:22:48 does anybody still use it? Nov 21 13:23:07 fw is better than usb, but ms decided to support usb Nov 21 13:23:57 sorry, it was mainly intel Nov 21 13:24:20 how could I confuse MS with Intel :) Nov 21 13:24:40 the both of them do write crappy software Nov 21 13:25:03 yes, intel backed usb because it fitted their world view Nov 21 13:25:10 a FAT pc in the center of it Nov 21 13:25:16 it did not have a blue tie though Nov 21 13:26:04 hi guys Nov 21 13:26:11 HI all, Nov 21 13:27:11 echo 1 > gpioXX/value set pin state to high while echo 0 > gpioXX/value set pin state to low : Nov 21 13:27:35 is there a command to give the pin an impulse of x msec ?? Nov 21 13:28:04 or should I use a echo 1 , sleep, echo 0 ??? Nov 21 13:28:47 yes Nov 21 13:29:08 via this API this is the only option Nov 21 13:29:14 and it will not be exact timing Nov 21 13:29:18 you cant do that from user space Nov 21 13:29:27 for exact timing you need to write a kernel driver Nov 21 13:29:33 or e.g use the PRU Nov 21 13:29:54 use an arduino ;) Nov 21 13:29:55 you can have something like that usign e.g. SPI Nov 21 13:30:10 then encode your GPIO states as a data pattern Nov 21 13:30:15 and send out over SPI Nov 21 13:30:19 hmmm too difficult to me.... Nov 21 13:31:53 i'm more practic with hardware, it's simpler to me to use and external timing device... Nov 21 13:32:23 monoflop Nov 21 13:32:31 BBB is no simple MCU, Linux is not the universal solution to all Nov 21 13:32:48 the BBB can do it of course Nov 21 13:33:01 you just have to keep Linux out of it Nov 21 13:33:35 depending on timing, it can be done on kernel level Nov 21 13:33:49 too bad they fucked up the FIQ though Nov 21 13:34:45 yes monoflop Nov 21 13:34:50 av500: why did that happen? Nov 21 13:35:59 timing is not so important , it can be an impulse from 30 to 100 msec... Nov 21 13:36:00 what? Nov 21 13:36:11 Freddie_: make a monoflop Nov 21 13:36:32 av500: with the FIQ Nov 21 13:36:56 they needed it for the "high security" part Nov 21 13:37:04 so its not working for the standard parts Nov 21 13:37:11 nobody needs to HS one of course Nov 21 13:37:48 aha, they = TI? Nov 21 13:38:29 THEY Nov 21 13:39:38 I see: http://e2e.ti.com/support/arm/sitara_arm/f/791/t/253773.aspx Nov 21 13:40:13 yes Nov 21 13:40:32 the whole discussion there is typical for TI Nov 21 13:41:42 meanwhile I'm still trying to find someone who knows anything about PLCs Nov 21 13:42:00 PLC? Nov 21 13:42:26 http://en.wikipedia.org/wiki/Programmable_logic_controller Nov 21 13:42:33 a peasant replacement for a microcontroller Nov 21 13:43:12 ah plc Nov 21 13:43:59 all I want is rs232 to a bbb, but the automation vendor says it'll load the plc too much Nov 21 13:44:25 ? Nov 21 13:44:41 I don't really get it either Nov 21 13:44:48 does the plc have rs232? Nov 21 13:45:02 rs232 comes as a 'module' typically Nov 21 13:45:21 I don't know much about plcs though Nov 21 13:45:55 I just find it hard to believe that a 2000 dollar piece of industrial hardware is going to struggle with some rs232 communication that I can trivially achieve on a 50 dollar arm cortex board with hardware threads Nov 21 13:45:58 they are used for nucular centriguges Nov 21 13:46:04 *fuges Nov 21 13:46:29 yeah they are Nov 21 13:46:35 they're also controlled by windows Nov 21 13:46:38 kinda scary, really Nov 21 13:46:45 Korra: high price does not mean they can do hw and sw properly Nov 21 13:48:01 that's true Nov 21 13:48:15 but still hard to believe, given that rs232 is kind of standard everywhere Nov 21 13:48:36 i thought a plc must be able to do things in parallel, and rs232 with a proper buffer should not load it Nov 21 13:48:49 I was told the same thing Nov 21 13:48:59 I was told the rs232 module has its own hardware memory buffer Nov 21 13:49:09 it should Nov 21 13:49:46 I'm 90% sure what the vendor is actually saying 'we've never done this before, we don't know how to do this, we're gonna pretend its impossible' Nov 21 13:49:48 or maybe they use 30 years old hw where a byte costs $100 Nov 21 13:50:09 and how do they interface their plc? Nov 21 13:50:18 analog io Nov 21 13:50:29 and proprietary link over ethernet of some sort for programming Nov 21 13:50:50 interesting Nov 21 13:51:46 the little experience I got with industrial automation is pretty dishearting Nov 21 13:52:04 its a world of windows NT servers and software-emulated 'relays' Nov 21 13:52:32 probably this is a good area to make money without too much effort, industry has money Nov 21 13:52:45 and to use old hw / sw Nov 21 13:52:56 yeah Nov 21 13:53:12 sounds ripe for a disruption Nov 21 13:54:17 GPIB is similar: complex + expensive Nov 21 13:54:27 what is Nov 21 13:54:51 look up on wikipeda, it is used for measurement etc Nov 21 13:56:21 yeah Nov 21 13:56:25 this is all low level stuff Nov 21 13:56:35 what my company actually wants is business intelligence level data Nov 21 13:57:20 big data? Nov 21 13:57:22 guys i'm trying to install armstrong distribution on BBB following this tutorial robotic-controls.com/learn/beaglebone/beaglebone-black-angstrom Nov 21 13:57:29 how a big do you need? Nov 21 13:57:33 not even that bit Nov 21 13:57:36 big* Nov 21 13:57:44 but when booting the BBB doesn;t acquire an IP from DHCP Nov 21 13:57:48 we're talking about 10 messages per minute saying what part is being manufactured Nov 21 13:57:55 by what machine Nov 21 13:58:54 Is it possible to plug a BB into a host computer via usb and present the BB as a usb hub. Then plug a usb flash drive into a BB. Scan the flash drive's files with ClamAV. If everything passes then allow the host to view the flash drive as if it were plugged directly into host? Nov 21 13:59:27 run clamav on the BBB? Nov 21 13:59:34 is there an arm version? Nov 21 13:59:35 av500: yes Nov 21 13:59:40 or is it open source? Nov 21 13:59:47 well.... clam was just an example Nov 21 13:59:59 some way to vet the files Nov 21 14:00:10 yes its possible Nov 21 14:00:13 I've actually been curious about this, haven't found any documentation on the usb mass storage gadget the bbb runs by default Nov 21 14:00:21 lingle: i dont think you can emulate an usb hub in software Nov 21 14:00:29 you dont have to be a hub Nov 21 14:00:35 but i haven't read chapter7-8 in detail Nov 21 14:00:39 composite gadget Nov 21 14:00:54 lingle, if possible it is not easy to do Nov 21 14:00:56 I guees you can tell musb to keep quiet on the bus until you scan and then enable it Nov 21 14:01:02 what are the lighweight distribution for the BBB a part from the angstrom ? Nov 21 14:01:03 there was a BB GSOC Nov 21 14:01:18 http://elinux.org/BeagleBoard/GSoC/2010_Projects/USBSniffer Nov 21 14:01:27 same principle, onehost, one device port Nov 21 14:01:29 pass through Nov 21 14:01:35 that'd work Nov 21 14:01:49 * KotH blames av500 for knowing too much Nov 21 14:02:08 av500: Yeah I saw that...i thought they couldn't get it to work.... though i could have my wires crossed Nov 21 14:02:12 if nothing else, I can provide bits of trivia Nov 21 14:03:20 I think it worked in general Nov 21 14:03:22 ds2: no? Nov 21 14:04:25 interesting project Nov 21 14:06:46 av500: Ok i will take a closer look at that GSOC project and see if I can bend it to my will Nov 21 14:07:06 btw, is there a speed benefit to use multiple bulk endpoints (e.g 8 x 64 bytes each) instead of one with 512 bytes. i mean usb is a serial protocol Nov 21 14:07:19 yes, serial Nov 21 14:07:36 one endpoint is usually enough Nov 21 14:08:04 usb speed is rarely limited by the wire speed Nov 21 14:08:10 more often by the SoC itself Nov 21 14:08:55 i am talking about full speed only. i always read about using multiple endpoints but I don't really understand the purpose of this, except if i have e.g. different measurement channels i want to keep separate Nov 21 15:07:51 hi guys! does anyone know, if tiwi-5e cape works on a beaglebone white with the latest angstrom demo image? Nov 21 15:21:43 fedlap: http://26-26-54.hardwarebug.org/30 Nov 21 15:42:27 http://www.RevenueJob.com/index.php?share=27529 Nov 21 17:46:00 guys i'm trying to install armstrong distribution on BBB following this tutorial robotic-controls.com/learn/beaglebone/beaglebone-black-angstrom Nov 21 17:46:06 but when booting the BBB doesn;t acquire an IP from DHCP Nov 21 19:23:24 I work for HP and we are sending a beagleblack board to India and our Classification team needs to know "is the ECCN 5A002.a1 Restricted or Unrestricted with CCATS document or Unrestricted Self-classified ? Nov 21 19:24:10 ECCN: that's a mouth full. Nov 21 19:24:37 ECCN: you do have the info at http://elinux.org/Beagleboard:BeagleBoneBlack#Export_Information, right? Nov 21 19:24:44 sorry about that, they are very picky Nov 21 19:25:28 I do now thanks Nov 21 19:27:07 _av500_: got a grab of that amp pdf maybe ? Nov 21 19:42:45 hi guys! does anyone know, if the tiwi-5e cape works on a beaglebone white with the latest angstrom demo image? Nov 21 19:44:32 or with any angstrom release? ;) Nov 21 19:55:34 fedlap: http://26-26-54.hardwarebug.org/30 Nov 21 20:42:00 [kernel] RobertCNelson pushed 1 new commit to 3.12: http://git.io/8bxgIQ Nov 21 20:42:00 kernel/3.12 f5b25de Robert Nelson: 3.12: import capes from 3.8 asis...... Nov 21 21:00:33 +1 Nov 22 00:00:31 greetings Nov 22 00:02:01 I have what appears to be a dead beagleboard black (A5C). It last worked when I powered down from the Ubuntu command line. Now I don't get a power LED. I've used both USB and Wall power, tried holding the power button for 8-seconds. No luck so far. Nov 22 00:02:50 I've been looking through documentation to see if there were any odd combinations, but as far as I can tell the PMIC isn't turning on. Nov 22 00:03:10 beagleboard.org/support/rma Nov 22 00:03:24 Heading that way, just wanted to check with the group first, thanks thews. Nov 22 00:03:53 no problem, there's no fuses of any sort Nov 22 00:04:06 if neither way show anything it's just about guaranteed that the chip is fried Nov 22 00:04:34 Is this common? Nov 22 00:04:55 from what I can tell, it's not Nov 22 00:05:13 it's probably pretty easy to do if you supply too much current into the input pins though Nov 22 00:05:25 from outside, or shorting to another pin that has higher current Nov 22 00:05:35 like 5v vcc pin Nov 22 00:05:46 and it's good to always use it with standoffs Nov 22 00:06:17 It was just sitting there, it runs my music server. I powered it off, unplugged it. Plugged it back in and nothing. Nov 22 00:06:39 does it run off of an sd card? Nov 22 00:06:40 Very strange, but requesting an RMA now. Nov 22 00:06:42 Yes Nov 22 00:06:47 Yes to SD card Nov 22 00:06:48 does it boot w/o sd card? Nov 22 00:06:56 Nope. No lights at all Nov 22 00:07:05 I did try it without the SD card. Nov 22 00:07:14 I'd definitely try the rma process then Nov 22 00:07:22 Doing it now. Nov 22 00:07:50 from what I saw on the forums they're pretty good about rmas, and are able to fix the boards pretty easily Nov 22 00:08:39 fastmonkey: how long did you hold down the power button? Nov 22 00:10:25 About 20 seconds Nov 22 00:10:37 The docs said 8, but I just kept holding to make sure I was well past that. Nov 22 00:15:53 Hi all, so I have a question about the BeagleBoard-xM. The Angstrom build is giving my team and I trouble with the eth drivers, so we're considering moving to Arch. Is this a good move or not? If so, what experiences/hiccups have you all had with going to and using Arch? Nov 22 00:38:12 This place is deaaaaaad. Nov 22 02:46:57 i switched the bone to Ubuntu and it went very well, but I can't speak to Arch Linux Nov 22 02:48:16 looks like he's gone already Nov 22 02:51:05 yo Nov 22 02:59:54 hey guys Nov 22 02:59:58 would you check my circuit Nov 22 02:59:58 http://flockdraw.com/cvumwa **** ENDING LOGGING AT Fri Nov 22 03:00:00 2013
