**** BEGIN LOGGING AT Sat Apr 18 02:59:57 2020 Apr 18 03:03:00 Dang. Apr 18 03:03:06 I just rebooted today. Apr 18 03:03:38 My cursor on this irc keeps moving by itself. Apr 18 03:13:15 check for mischievous crickets near it they may be superstitiously moving it. Apr 18 03:20:53 I do not understand. It was a poltergeist on the irc. Apr 18 03:21:24 GenTooMan: I have some 11.2 (recommended) servos! Apr 18 03:21:33 11.2v, sorry. Apr 18 03:21:47 Guess what is going to happen now? Apr 18 03:22:09 I am going to use the BBB w/ the relaycape to handle these pups. Apr 18 03:22:48 First issue, the hardware needs to be reconfigured. They are 300 degree continuous servos! Apr 18 03:23:40 Alterations are making headway in the source so far, the hardware will take aim soon, and things are going to work! Apr 18 03:24:29 These servos have alarms and LEDs. yikes. Apr 18 03:24:53 I cannot wait to get my first error. Apr 18 03:34:20 I just had some odd, pink icons all over my computer. Odd days, mate, odd days. Apr 18 03:38:25 umm read the manual Apr 18 03:42:46 What manual? The emanual? Apr 18 03:43:13 I am. I am reading it and changing the source to suit my specific servos. Apr 18 03:44:19 See, the source for running the motors was for MX and I have AX servos. Apr 18 03:44:33 "Fine tune!" Apr 18 03:48:48 Now, if I can only figure out how to use UART2 on this BBB w/ the RelayCape attached. Sheesh. Apr 18 03:51:53 The .c file compiled. This is nice. Now, I think I have to test it w/ /dev/ttyS2. Hmm. Apr 18 16:08:04 I wanted to use a BBBW for industrial instrumentation. The first thing I wanted to do was interface it with RS485. My impression now is that people have been wanting to do this since at least 2013 with limited to no success. Apr 18 16:26:16 lol what Apr 18 16:26:31 oh I guess he had limited to no patience Apr 18 16:26:55 that was a statement not a question... anyhow Apr 18 16:27:27 well I could nevertheless add an unsolicited "your impression is very wrong" Apr 18 16:27:46 or more charitably perhaps query what give him that impression Apr 18 16:27:50 all this is moot however Apr 18 16:29:15 all I was going to say is "RS485" is a class of seemingly random configurations what implementation are you referring too? Apr 18 16:29:42 well no, RS485 is an electrical spec :P Apr 18 16:29:47 ;) Apr 18 16:34:44 right but obviously he wasn't talking about the spec.. RS422 and RS232 are electrical specs completely nor is RS485 what it was truely however I never bothered to find out, Lost in the mist of time I guess. Apr 18 16:35:24 I still suffer from contractionitous (random contraction misuse) Apr 18 16:35:32 I mean he was no doubt talking about the software aspects of using an uart for half-duplex communication with a driver-enable signal, possibly requiring rapid turnaround Apr 18 16:54:30 well maybe the person will return and answers can be questioned Apr 18 17:02:09 I have to ask. set_: What are you working on? I've seen misc chatter about it, but don't have much history from this channel. Apr 18 18:49:49 Me...oh. Nothing really. Just trying to read and apply what I have learned. Apr 18 19:07:24 I mean...I will be working on a 11.2v (recommended), 300 degree continuous rotation servo w/ the BBB soon. I have been working on it recently but I am just getting the sdk down and the finding better ways to connect to the BBB. Apr 18 19:28:25 360 you mean? Apr 18 19:29:32 so servo input controls the speed of the movement not the actual movement? I presume you need to monitor servo current and fun stuff like that. Apr 18 20:08:19 sorry about that, IanWizard. If you need any particulars, let a brother know. Apr 18 20:19:46 set_ I've read most servos use or require a 5V signal however documentation to that affect on the servo is sorely lacking in fact most servo's have next to nil documentation. So I am at an impasse with the servo cape as a consequence. Apr 18 20:23:53 Oh. Apr 18 20:23:55 Okay. Apr 18 20:24:56 GenTooMan: Please look here for the docs. on these servos ---> http://emanual.robotis.com/docs/en/dxl/ax/ax-12a/ Apr 18 20:25:35 I am reading now on TTL and totem output. I think if I wire these pups correctly, I can get a switch to turn them on plus have the logic work from the BBB. Apr 18 20:27:22 Easy, no. Fun, yes. Worth it, double-bubble! Apr 18 22:22:47 No backups, a restarted server, and "back to the old drawing board." Apr 18 22:22:49 Ouch. Apr 18 22:32:59 GenTooMan: You are right, too. Servos have terrible datasheets like most cheap, DC motors. Apr 18 22:33:35 I have guessed many times as to how to wire something up b/c of the lack of data on the datasheets, e.g. if there was one at all. Apr 18 22:34:24 I mean. I can plug it in to a supply and make assumptions but I am not handy enough as is to make "above par" assumptions right now. YOu know this, man. Apr 18 22:39:09 That book, "Bad to the Bone," has some nice .c file translations into source from the BBB file system idea b/c of the Linux Distro used. Apr 18 22:39:57 I am sure I am old news stating this fact but I have been reading books on python and older models of libraries dedicated to the BBB. Apr 18 22:40:12 So, this refreshing difference it nice! That is all for now. Apr 18 22:40:22 it = is Apr 18 22:46:16 I might have to add gears one day. This bolting everything down on my bots is getting old. Apr 18 22:49:45 Or belts! Apr 18 22:56:55 Does anyone use belts, gears, or chains w/ their motors w/ the BBB? Apr 18 22:58:59 I have this gear ratio book and some belt/pulley ideas in the same book. Apr 18 22:59:44 I can use some motors, some odd ratios, and the BBB. Then, the documented ideas can be posted. Does this idea sound good or nice? Apr 18 23:15:43 I suggest only using timing belts and pulleys unless you want to drive yourself crazier. Apr 18 23:19:17 Ha. Apr 18 23:19:26 What do you think I do, exactly? Apr 18 23:19:29 Ha. Apr 18 23:22:30 I was seeing standard V belts and pulleys which won't work well. Apr 18 23:23:06 Hmm. Why would belts and pulleys not work well? Apr 18 23:23:13 B/c of timing? Apr 18 23:23:57 Sometimes people are in awe of the spin/rpm instead of function. People love movement. Apr 18 23:25:06 I mean, look at each industrial/oil complex around the country (or at least circa 13 years ago). There was a motor dude and engine guy in each complex (at least one). Apr 18 23:26:36 I can still go locally to people who rewind and dust-proof motors. I think this is a neat commodity. Apr 18 23:26:55 right so let me repeat timing belts and pulleys because you want to keep your position accurate. Apr 18 23:27:07 Okay. Apr 18 23:27:17 timing belts, not v-belts. Got it. Apr 18 23:27:39 timing belts won't slip if they do they make a HUGE noise and it's obvious something is wrong. Apr 18 23:28:20 GenTooMan: You are industrial already. I am just low grade fun. I have a lot to learn, still. Eeerrrrnt! Apr 18 23:29:09 GenTooMan: I posted on google groups under a newbie post. I found this fellow was working on servos that handle 6v. Apr 18 23:29:21 Mine handle 11.2v. Apr 18 23:29:31 I jumped in and tried to make nice. Apr 18 23:30:46 See here: https://groups.google.com/d/msg/beagleboard/a8av9JKNdy8/HFu6JObSAQAJ. Apr 18 23:31:31 I hope I can help him/her help me help or something. I wonder what they are making w/ 6 to 8.4v servos, heh? Apr 18 23:36:44 11.2v is the tricky part. Apr 18 23:37:06 your servo's require a UART channel to control then and operate from 9 to 12V it defaults to 1mbps the word type isn't given so ... Apr 18 23:37:06 I do not know how to make a 3S LiPo circuit yet. Apr 18 23:37:47 So? Apr 18 23:41:09 so you have a simplex communication channel on one of the lines (5V?) and you have to switch the direction of communication to receive a response from the servo. It's multidrop which means a bunch of things are listening on the single ended communication line. This has issues because single ended communication is noisy (on a good day) so you will get issues with bad communication. Apr 18 23:43:12 I'm not sure what they were thinking but RS485 would have been a more appropriate choice. Apr 18 23:44:14 I need, say 12v to make it simple, 12v of power from a source to my servo Vin, a UART connection to one of the pins in the form of a op-amp within a circuit, and GND? Then, I can figure out what exaclty I am doing w/ the issues at hand before my BBB turns into mush? Apr 18 23:44:15 ... Apr 18 23:44:31 I think the RS485 is within the servo. Apr 18 23:45:51 See, they want to sell this converter (TTL) w/ their hardware. Apr 18 23:45:57 This is what I am trying to get around for now. Apr 18 23:47:50 Sorry. That is, the RS485, is on the controller. Whatever the controller looks like, it must be that TTL device I was discussing. Apr 18 23:49:26 Anyway, I need to use Half-Duplex type. This circuit will help me more than the other. I have only three pins on my Servo. Apr 18 23:52:46 I have a CB radio of the servos now. Ha. Apr 18 23:52:51 so let me explain to you that you need to use the equivalent to 5.4.1 on the documentation page to communicate with the servo. Apr 18 23:53:01 Okay. Apr 18 23:54:56 HDX, over. Apr 18 23:56:17 you will need to level shift the BBB UART signals to interface into that circuit Apr 18 23:59:24 Would that dc-dc MicroAny Volt do the trick, you think? Apr 18 23:59:55 I will get one if that micro AnyVolt cannot do it. Apr 19 00:00:50 https://www.dimensionengineering.com/datasheets/AnyVoltMicro.pdf Apr 19 00:01:01 This is like me powering a small amp. Apr 19 00:01:14 Well, in reverse. Apr 19 00:02:26 I see I need to be smarter about this idea than previously thought. Apr 19 00:03:52 So, I can use this AnyVoltMicro, additional circuitry, and a linear v. reg. or op-amp. Apr 19 00:05:40 um set_ do you use an op amp to hook a uart up to something? Apr 19 00:06:28 I do not think so but I can check the old book about that idea. recently, I have not used one to handle uart comm. or ever. Apr 19 00:07:08 oh. Apr 19 00:07:11 right the UART is a 3.3V signal that is high or low on the BBB ... so the answer is no. Apr 19 00:07:19 Op-amps are for analog. Apr 19 00:07:21 Okay. Apr 19 00:07:28 adc stuff. Got it. Apr 19 00:07:35 No. Apr 19 00:07:55 we are in the weirdly simple realm of digital (for the moment) Apr 19 00:08:16 I thought they could be used to prevent digital signals from reversing back into the uart channel/pin. Apr 19 00:08:28 <<< wrong! Apr 19 00:10:37 it's OK to be wrong just be sure to verify if you are or not. Apr 19 00:13:23 I did and I did not verify. I was thinking of past ideas w/out researching. Oops. I will make sure next time. Apr 19 00:14:26 GenTooMan: I found some ttl to uart converters. Sort of but I wanted to show you in case their circuitry is better than my home brewerd breadboard. Apr 19 00:16:26 https://www.newegg.com/p/2S7-007G-013G5 is something I found. I will need to further investigate this idea. Apr 19 00:18:54 Oops again. This is just the converter from "four pin" to "three pin" for UART communication (RS485 to TTL). Forget it. Apr 19 00:19:00 I will have to make the connection. Apr 19 00:21:29 set_ you have a bread board? Apr 19 00:21:44 Yes. Apr 19 00:22:04 I am looking at LM3281 right now. I am trying to find the correct buck converter for this project. Apr 19 00:23:37 get the equivalent DIP parts you saw in section 5.4.1 HC126 and HC04 they should be available from mouser or digikey. Wire them on the plug board. Then you just need a level shifter to shift 3.3V to 5V for the BBB Apr 19 00:24:10 bread board I mean you can jumper from the BBB to the bread board and from the bread board to the input of your servo. Apr 19 00:24:25 Right. Apr 19 00:24:26 Okay. Apr 19 00:24:52 I have the shifter w/ me, the BBB, and the breadboard. Apr 19 00:25:23 The issue to me is the power adaption from the battery. Apr 19 00:27:20 I can and will start w/ lower voltage if necessary. I know it stated that 11.2v is recommended but that is not doable right now. Apr 19 00:29:51 well set_ the communication is at 5V and they stated 9 to 12V for the power Apr 19 00:30:32 the only thing that needs level shifted is between the BBB RX TX and direction pins and the circuit you saw at 5.4.1 Apr 19 00:30:46 Okay, okay. Sorry. The HC126 and HC04 have active parts online which I found but... Apr 19 00:30:59 Which of those active parts should I get? Apr 19 00:31:09 Okay. Apr 19 00:31:34 I do not think I have it covered. I do not own a HC126 or HC04. Apr 19 00:33:41 I am finding the through-hole versions now. Apr 19 00:37:47 I noticed that HC126/HC04 only work w/ up to 6v. Would the TTL circuit guard against overvoltage? Apr 19 00:38:54 Or...Does the HC126/04 come into the circuit later, i.e. after I change logic? Apr 19 00:42:11 that circuit is from the manufacturer to interface into their servo correct? I don't believe you need anything more than that for the data line on the connector Apr 19 00:42:56 that connects to the servo directly. Apr 19 00:44:43 Oh. Okay. Apr 19 00:45:44 So, let me make sure i understand, the two chips referenced (HC126/HC04) are to be put in place of what they recommended. Apr 19 00:46:07 So, instead of their chip reference, I use the HC models. Apr 19 00:47:10 Okay. I got it now. Those are the HC chips we are discussing. Apr 19 00:47:12 Okay. Apr 19 00:47:14 Yikes. Apr 19 00:48:22 I need two HC126s and one HC04. Apr 19 00:48:37 No Apr 19 00:48:42 No? Apr 19 00:48:55 They are what they recommend. Apr 19 00:49:08 Right. Apr 19 00:49:13 It's straight from the manufacturer that's what they recommend. :D Apr 19 00:49:38 Okay. I thought you were making a transfer of ideas from one chip to another. Sorry. Apr 19 00:50:09 I thought they had listed xxx and you wanted to use a bxbx instead. My bad. Apr 19 00:50:37 Right go to here and see http://emanual.robotis.com/docs/en/dxl/ax/ax-12a/#communication-circuit Apr 19 00:50:43 I am there. Apr 19 00:50:57 I know. I just did not know you were referencing that exact part. Apr 19 00:51:26 So, I need two of the HC126s and one HC04. Okay. Apr 19 00:53:09 Um you do know how many parts are in one package don't you? an HC04 has 6 inverters and an HC126 has 4 of those circuits but you should get 5 ICs because you can blow them up easily. Apr 19 00:53:31 I get the mfg. websites labeling still goofed up. So, on TI.com, it states SN74HC126 and on another site or different mfg, it would state something different. Like w/ the schematic, it shows 74HC04. Apr 19 00:53:33 Okay. Apr 19 00:53:38 Oh. Apr 19 00:53:53 So, w/out the proper voltage, they go out easily. Good to know. Apr 19 00:54:07 Over 6v and poof. Apr 19 00:54:56 Okay. So, five of each. Okay. I will get five of each to be on the cautious side. Apr 19 00:55:16 they are cheap Apr 19 00:55:35 Nice. Apr 19 00:55:47 S & H is bogus. I might have to wait until I need more items. Apr 19 00:56:14 You know. BOM smarts. Apr 19 00:58:39 GenTooMan: I found them but they have tons of choices. I need to find what through-hole acroynms the mouser people use these days. Apr 19 01:00:27 I do not want to contact them but Off to look online. Google! Apr 19 01:01:07 package DIP try that Apr 19 01:01:29 What does DIP mean? Apr 19 01:01:42 I tried through-hole but the Internet busted. Apr 19 01:02:48 They have reel, mouse reel, and cut tape. Apr 19 01:04:31 Digikey has soic. No dip. Apr 19 01:05:55 DIP dual inline package mouser has the parts in DIP patching Apr 19 01:06:03 packaging Apr 19 01:06:03 I found through hole on DigiKey but it is not a TI chip. Does it matter? Apr 19 01:06:07 Okay. Apr 19 01:06:43 https://www.digikey.com/products/en/integrated-circuits-ics/32?k=dip%20package%20HC04&newproducts=1 Apr 19 01:06:44 through hole is DIP if they idiots entering data and digikey are that stupid Digikey deserves them (LOL) Apr 19 01:06:53 Okay. Apr 19 01:06:55 Okay. Apr 19 01:07:01 Look at the link, mr. lol. Apr 19 01:07:02 Ha. Apr 19 01:07:17 DIP! Apr 19 01:07:26 it says DIP right after 32?k=dip <--- look at the URL Apr 19 01:08:29 I know. I saw it. I typed it in like you described. Apr 19 01:08:34 DIP! Apr 19 01:09:02 well new stuff doesn't come in it because through hole isn't used much anymore. Apr 19 01:09:16 Oh. Okay. Apr 19 01:09:18 Hmm. Apr 19 01:09:49 For testing and tests, it works for me if they would figure out to universalize the breadboard. Apr 19 01:14:09 I remember one day I harassed @zmatt for weeks about wiring something when the breadboard was faulty and not like the other breadbaords I have used. Apr 19 01:17:58 yeah faulty bread boards can be troublesome Apr 19 01:19:04 Yeppers. Apr 19 01:19:27 Well, I am going to order these buggers and see how long it takes for them to get 'em to me. Apr 19 01:20:08 Just for reference, I need non-inverted right? Apr 19 01:26:03 Hi guys. Apr 19 01:27:16 set_ If your running a BBAI can type in cat /proc/device-tree/model and give me the results? Apr 19 01:28:48 set_ Will the relay for the BBB work on the BBAI? Apr 19 01:28:59 set_ Will the relay cape for the BBB work on the BBAI? Apr 19 01:29:52 Hello! Apr 19 01:30:07 set_ If your running a BBAI can type in cat /proc/device-tree/model and give me the results? Apr 19 01:30:10 set_ Will the relay cape for the BBB work on the BBAI? Apr 19 01:30:36 KenUnix: I think the RelayCape only works for the BBB and not the BBAI b/c of the pin change from the chip. Apr 19 01:30:49 So. Apr 19 01:31:15 So there is no relay cape for the BBAI? Apr 19 01:31:27 Not yet. Apr 19 01:31:32 But...if you are trying. Apr 19 01:31:48 Let me make you understand the issue from what I gather. Apr 19 01:32:37 The EEPROM onboard this RelayCape is set to make sure that, for instance, P9.41 on the BBB is set to GPIO. RIght? So... Apr 19 01:33:35 If the BBAI is having complications w/ pin muxing, from what I have heard, then the EEPROM which is set already onboard the Cape has conflicts in two ways: Apr 19 01:33:53 1. Pinmux faisl Apr 19 01:33:58 fiasl = fails Apr 19 01:34:30 2. EEPROM is meant for a different chip and different board all together Apr 19 01:34:43 But. If you can do it, do it! Apr 19 01:34:59 Let me plug in the AI real quickly. Apr 19 01:35:15 I also note there are no cases for the BBAI. Apr 19 01:35:48 You mean, the muxing of the pins? Apr 19 01:35:54 Well cat /proc/device-tree/model and give me the results anyway Apr 19 01:36:04 Okay. I just plugged in. Please hold. Apr 19 01:36:28 Ut oh. Apr 19 01:36:38 I haven' t found any cases for the BBAI. Apr 19 01:36:48 Utoh??? Apr 19 01:36:51 I forgot. I put the new image on the board. I never booted. It may be 15 minutes. Please hold. Apr 19 01:37:10 I haven' t found any cases for the BBAI. Apr 19 01:37:37 Okay. Apr 19 01:37:38 I did. Apr 19 01:37:43 It booted rather quickly. Apr 19 01:37:48 Yikes. Apr 19 01:37:54 Do you think many people with BBB use the relay cape? Apr 19 01:38:15 Nope or they do not boast about it. Apr 19 01:38:27 Either way, it is better than the cheaper alternatives. Apr 19 01:38:49 Who are you going to chat w/ or call if your OOCOCXX relay board dies? YOu know? Apr 19 01:39:17 Hey. Apr 19 01:39:20 So all that trouble I went to with that program relays.bas is for naught? Apr 19 01:39:29 No. Apr 19 01:39:35 It is for future consumption. Apr 19 01:39:53 People read the articles, hopefully. Then, they can learn from what they have read. Apr 19 01:40:24 Things change drastically. I like the board but I did not know of other people before you who liked it. Apr 19 01:40:32 I like it. Apr 19 01:40:36 Well since posting I added inline help and error detection and detection of which BB Apr 19 01:40:40 board = Cape Apr 19 01:40:49 Hmm. Apr 19 01:40:53 I will check it out again. Apr 19 01:40:59 Error! Apr 19 01:41:00 Ha. Apr 19 01:41:41 It's not up there yet it may be a waste of my time Apr 19 01:41:51 GenTooMan: The NJ co. that is producing these HC04s are trying to charge me $10.04 for S & H. Apr 19 01:42:04 KenUnix: No. It would not be. Apr 19 01:42:07 Well cat /proc/device-tree/model and give me the results anyway Apr 19 01:42:11 I did. Apr 19 01:42:14 Please hold. Apr 19 01:42:18 I will get you the info. Apr 19 01:42:32 BeagleBoard.org BeagleBone AI Apr 19 01:43:37 set_ LOL ok let me hit you with a brick, I mean help you with it. Apr 19 01:43:48 I've added code detection so now I can look fir "AI" also Apr 19 01:44:02 Okay. Apr 19 01:44:06 A brick? Apr 19 01:44:10 Man, that sounds painful. Apr 19 01:45:06 The ti chips were less expensive and have cheap shipping. NTE charges out the wazoo. Apr 19 01:45:56 KenUnix: Have you messed w/ the MotorCape or the ServoCape? Apr 19 01:45:58 set_ don't by NTE it's just the same manufacturer repackaged Apr 19 01:46:06 oh. Okay. Apr 19 01:46:11 I will get rid of those. Apr 19 01:46:14 I also added batch processing if you want to go interactive you reference a file with the commands you want to execute and the output is quiet. To check the results you cat the file relays-stdout.txt Apr 19 01:47:47 HC04. Apr 19 01:48:02 NTE is quite the wrangler in the US. Apr 19 01:48:04 Sheesh. Apr 19 01:48:39 You would say bwbasic --tape allon.inp relays.bas and that would turn on all the relays Apr 19 01:48:57 set_ https://pastebin.com/Lm1NkHKP basically 3.46 for 10 3.48 for 10 you can get other parts that would be useful at the same time Apr 19 01:49:07 You would say bwbasic --tape alloff.inp relays.bas and that would turn offf all the relays Apr 19 01:50:34 set_ truth be told I have come up with a 2 part circuit that's SMT that does the level shifting and direction switching in 2 gates. Apr 19 01:50:59 Nice. Apr 19 01:51:23 Hmm. I wonder why they are telling us about that many different chips w/ all sorts of gates in them. Apr 19 01:53:38 the packages are different and the ratings for the IC's are different they are similar in that they operate mostly the same Apr 19 01:56:21 Oh. Apr 19 01:56:23 Okay. Apr 19 01:56:42 THat tells me to ask questions. Aw. Apr 19 01:57:14 Batch processing, yea boy. Apr 19 01:57:57 gates. Bill Gates. HaHa Apr 19 02:01:23 GenTooMan: I am going to try to order from digikey. They have cheap, $4.99, S & H. Apr 19 02:01:33 Mouser is giving me the willies. Apr 19 02:02:32 What's this? Roll your own? Apr 19 02:04:29 Yea boy! Apr 19 02:04:35 Make a Cape day! Apr 19 02:05:13 I have seen some blank capes to roll your own Apr 19 02:05:34 now a friend of mine met Bill Gates when he was starting out. He was complaining about people stealing his BASIC. He was selling his basic at a computer meet up in the early 70's. Apr 19 02:05:36 GenTooMan: Okay. I found the through-hole items needed that were listed on their site, i.e. plus I got the digikey checkout w/ the S & H. Apr 19 02:05:52 Ha. Apr 19 02:06:12 "Where is my basic? Come on guys? WHo took it?" Apr 19 02:06:21 but .. do you know where Bill Gates got his basic? MIT he just changed the copyright information on the code. Apr 19 02:06:35 Zoinks! Apr 19 02:07:02 Tell me about it. I remember the first PC running CPM Apr 19 02:08:03 Didn't Dartmonth really write the first basic? Apr 19 02:08:08 You know why IBM went with CPM? Because the only person left to speak with IBM was the owners wife and she found something she didn't like and the deal was off. Apr 19 02:08:34 IBM didn't go with CPM (sigh). Likely but MIT license means anyone can use it so BG did. Apr 19 02:08:48 "I told you she hated the color blue!" Apr 19 02:09:15 set_ probably not too far off, it's hard to say what happened but the IBM lawyers were apparently ticked off. Apr 19 02:09:30 I confused tell me about wife? Apr 19 02:10:26 the owner of the company was out of town and IBM was "in a hurry" and the wife was at the negotiation table not the owner. So it's likely things didn't go great. Apr 19 02:11:06 Oh god the early days of networking, barf! Conner drives 2MB lans Apr 19 02:11:49 hey everyone knows getting ethernet to even be a standard took hell on earth and stamina from the great negotiator to happen. Apr 19 02:12:18 Now adays people arn't happy with 1000MB lans Apr 19 02:13:02 Yeah.. but going beyond 1G is 1 very expensive and 2 very difficult. Apr 19 02:13:08 Cabletron hubs Apr 19 02:14:03 the challenges of RF communication rears it's ugly head with > 1G Apr 19 02:14:07 Yea, I got Wifi so how fast is it I get asked Apr 19 02:14:44 WiFi well if it's all you have... I guess you will have to deal with it. Apr 19 02:15:06 Oh yea, special schelded patch cables cat 7 Apr 19 02:16:02 To add more joy WiFi repeaters Apr 19 02:16:25 More, more, more. Just like me and tonight. I got the AI to FTDI for testing in case I screw up something. Apr 19 02:17:00 Along w/ the correct chips. I never knew buying was so tedious. Apr 19 02:17:04 Where I live I can see the network of the car dealer asross the street Apr 19 02:18:13 'nmap' pickes it up. And connmanctl see it on the BBB Apr 19 02:19:06 Hmm. How do you know it is that dealership? Apr 19 02:19:06 I ip'd into one of their servers and had a look around Apr 19 02:19:13 Ha. Apr 19 02:19:45 The names like Kennedy Apr 19 02:19:52 '97 volvo on the 21st of March? Apr 19 02:20:37 Oh and no password protection Apr 19 02:21:13 Oh. Apr 19 02:21:53 Yea, the server was for the Penna. Dept. of transsporation Apr 19 02:22:26 a wifi repeater is a nuisance it just triples the amount of bandwidth usage even if it extends range. Apr 19 02:22:37 really PA can be so backwards at times. Apr 19 02:23:22 They have a server there because they do instactions nd licenseing Apr 19 02:23:54 Aw. PA = Pickle Advocate? Apr 19 02:24:03 Easy is better seems a motto. However they are more than willing to make sure you pay for their lack... literally in most cases. Apr 19 02:24:10 They have a server there because they inspections and licenseing Apr 19 02:24:23 Right - o Apr 19 02:25:14 Well GenTooMan, you talked me into it. I got the chips, a converter, and a PowerCape! Apr 19 02:25:15 Maybe I should put a hot dog on that server Apr 19 02:25:44 Ut oh, hot dog! Apr 19 02:25:59 rabbit... rabbit.. Apr 19 02:26:15 set_ if anything you can play with the chips :D Apr 19 02:26:38 I know. I need to figure out how to use them to make these darn servos move, move, move. Apr 19 02:27:34 Chip-a-holic and my senses tell me it may be another year before this venture takes place. Apr 19 02:28:04 But, I will try to keep that page up in google Chrome for reference. Apr 19 02:28:05 I suggest you study the circuit 5.4.1 and print a copy of it. Also get the data sheets for the IC's. Apr 19 02:28:17 I got the datasheets. Apr 19 02:28:34 I should print out the circuit. You are right. Apr 19 02:31:33 I thought there was a servo cape? Apr 19 02:32:15 There is! Apr 19 02:32:19 Are you using it? Apr 19 02:32:36 Me, no Apr 19 02:32:39 Dang. Apr 19 02:32:48 That chip is giving this brother some issues. Apr 19 02:33:06 PCA9685! Apr 19 02:36:47 Did you see https://www.element14.com/community/community/project14/visionthing/blog/2019/11/16/beagleboard-ai-brick-recovery-procedure There a section on servo Apr 19 02:38:15 Nope. Heh? Apr 19 02:38:19 Servo! Apr 19 02:38:23 Let me go and look. Apr 19 02:40:20 Oh. Apr 19 02:40:31 Yea. That fellow has done some nice things w/ his work for the AI. Apr 19 02:43:55 Ever look at the BBBlue? Apr 19 02:45:15 Well look here http://linuxgizmos.com/robotics-savvy-beaglebone-blue-turns-on-the-servos/ Apr 19 02:47:23 Yep. Apr 19 02:47:32 I have one of those bbblues. It flies! Apr 19 02:48:30 and w/out me being mad at it. Apr 19 02:49:09 Seems the BBBlue has a lot of expansion capability Apr 19 02:49:37 I think the only issue I have come across is finding people w/ the crimp tool to sell cheap versions of the cabling w/ crimps. Apr 19 02:50:07 roll your own Apr 19 02:50:08 But yes. I think so too. It has all sorts of connectors on it. Apr 19 02:50:15 I would but... Apr 19 02:50:39 The crimping tool is expensive and I do not think it comes as other crimping tools would arrive. Apr 19 02:50:46 There is the idea of the dies. Apr 19 02:50:55 the biggest issue with a servo cape is power for the servos I've found. Apr 19 02:51:21 You mean, they are all on or all off? Apr 19 02:51:41 Or...the 5v supply? Apr 19 02:51:48 servo's have a high peak current draw so you have to have a LOT of power on hand for them. Apr 19 02:53:24 The only servo's I knew were way back with syncro servers. Turn one and watch the other one move. Apr 19 02:54:05 never flew an RC plane? Apr 19 02:54:17 not me Apr 19 02:55:10 I was hiding behind the door when God gave out planes. I thought he said brains. Apr 19 02:56:59 oh night of the living dead flash back... Apr 19 02:58:44 set_ which uarts are normally available / used on the BBB headers? **** ENDING LOGGING AT Sun Apr 19 02:59:57 2020
