**** BEGIN LOGGING AT Wed May 14 03:00:00 2014 May 14 05:01:23 so one of your guys here figured out how to do the new cregister ABI with the linker file? May 14 05:01:41 the README.txt is so so vague :) May 14 05:03:00 what are you doing that is so loose in timing htat you can use C? May 14 05:04:38 ah found it in the log May 14 05:04:41 ds2, not everything needs nanosecond accuracy May 14 05:04:52 usec accuracy is some timers enough May 14 05:09:03 only part i need nanoseconds is the bitbanging out the LED data May 14 05:09:08 hmm no side May 14 05:09:10 *sid May 14 05:18:43 shouldn't that be better done on the ARM? May 14 05:19:06 ds2: ah no May 14 05:29:17 mranostay: what's the reason in your case? May 14 05:31:27 ds2: 90 fps that needs to be 1.25 microsecond exactly May 14 05:38:27 Oh you need timing accuracy but not timing resolution? May 14 05:45:09 ds2: well i have pure assembly for that core May 14 05:45:26 getting data for next frame doesn't need to be nanosecond accurate May 14 05:46:43 jkridner: btw you'll want to pull my 2.0.0 fixe May 14 05:46:46 hi karki May 14 05:47:24 will now build with the 2.0.0 toolchain with the correct PRU_C_DIR variable May 14 05:47:48 i want to cluebat the person than changed the delimiter from : to ; May 14 05:48:03 does the 2.0.0. toolchain support _asm_ or equiv? May 14 05:49:30 yes May 14 05:51:44 hmm pru0 code fails May 14 06:00:01 remoteproc needs updates May 14 06:01:03 mranostay: to which repo? May 14 06:01:12 pruduino? May 14 06:02:30 hold off need to find a remoteproc issue May 14 06:30:23 morning May 14 06:36:18 mranostay : Hi! May 14 06:36:54 fixed the "bug" kinda May 14 06:36:59 need to sleep for day job May 14 06:37:12 * karki has his last theory exam tomorrow....... and it's data mining ;) May 14 06:40:00 not the issue :/ May 14 06:42:41 * karki is checking out mranostay 's patch, he may fail his data mining exam if he gets to distracted ;) May 14 06:43:59 panto : I'll have my video ready by today. will start working from tomorrow! Sorry I have been a bit caught up with my exams :/ May 14 11:04:34 * Abhishek_ likes the noise reduction capabilities of Audacity May 14 13:49:01 jkridner, we are assuming that all images will be available in just one Flickr account? May 14 13:49:57 * Abhishek_ is recording the presentation now May 14 15:53:30 hey guys.. May 14 15:53:38 no disdi yet I guess May 14 15:57:06 Hello all, video going to be uploaded shortly May 14 16:00:49 Hello joel_ May 14 16:01:21 Hello all! May 14 16:01:59 hello all May 14 16:02:11 Greetings May 14 16:02:17 Hello everyone! May 14 16:02:43 ahoy May 14 16:03:17 <_av500_> Hello May 14 16:03:42 hi May 14 16:03:44 hey there, all May 14 16:03:52 Hi @_av500_ May 14 16:04:47 *splat* May 14 16:05:00 disdi_, answering that question- you can boot from emmc (mmc1) when testing mmc0 so that should be fine May 14 16:06:43 provided that the board I get hass eMMC May 14 16:06:55 beaglebone black right? it does. May 14 16:07:16 I am not sure I get beaglebone black May 14 16:07:38 suppose I dont have....then what were the options May 14 16:07:48 <_av500_> I think all students will get a BBB May 14 16:08:27 That's what was asked in the hw docs sheet, so I expect it to be May 14 16:08:51 ok.....then thats ok May 14 16:10:37 Cathy has begun shipping hardware, but the process is always a bit convoluted and slow. May 14 16:10:41 not sure what happened there with my net connection to freenode. May 14 16:10:45 DiegoTc: no, the tutorial developer's Flickr account. May 14 16:12:01 hi disdi_, DiegoTc, praveendath92, Abhishek_, karki, rseethamraju, vmayoral May 14 16:12:09 hey May 14 16:12:13 Hey May 14 16:12:23 thanks for showing up and hopefully you aren't completely idle right now. :-) May 14 16:12:27 Hi May 14 16:12:39 Nope. Following. May 14 16:12:52 Hi Abhishek_ May 14 16:13:15 first order of business is to review the agenda... anyone got agenda items? May 14 16:13:23 How is the video going? May 14 16:13:40 Agenda: Only that I have to leave early again May 14 16:13:53 * jkridner wants confirmation again that students are getting time with mentors and feel ready to start coding next week. May 14 16:14:08 * jkridner also wants to confirm that mentors feel their hardware requests have been taken. May 14 16:14:17 <_av500_> praveendath92: you have HW? May 14 16:14:18 (and that there is a plan to fulfill them) May 14 16:14:55 yes I’m getting time with mentors . And I kind of started already. May 14 16:15:10 Yeah. I have a borrowed one but I may have to return. May 14 16:15:25 joel an I have also started....just waiting for the HW May 14 16:15:52 However i can currently test with linux on my pc and mobile. May 14 16:15:58 jkridner: all good on my side. I'm really pleased with the mentoring. May 14 16:16:02 rseethamraju, VoltVisionSteve: I talked with Cathy about the hardware we were looking at yesterday and that's all set May 14 16:16:13 ok cool! May 14 16:16:15 <_av500_> praveendath92: your BBB is on its way May 14 16:16:19 I'm in communication with you(jkridner) and VoltiVision. Steve told me this week was a difficult week for him. But we always talk about the project. May 14 16:16:39 @_av500_ hope it doesnt give any problems when running on BBB May 14 16:16:47 alexanderhiam: thanks. May 14 16:16:57 Sorry No Steve but David May 14 16:17:22 Cathy sent 7 boards to India and had addresses for 3 of them. (not all were for students). I think 2 needed addresses on the last e-mail exchange I saw. May 14 16:17:39 boards should have started arriving or arriving soon to students in India. May 14 16:17:55 I believe one student was trying to make arrangements to pick up a board in Bangalore? May 14 16:17:59 I'm in touch with cdsteinkuehler, ds2 and mranostay via mail too and we have discussed a few points regarding latencies and PRU firmware, May 14 16:18:00 I hope to run a PRU test firmware tomorrow. May 14 16:18:11 DiegoTc: this week is crazy for me too thanks to Maker Faire. May 14 16:18:34 ok. May 14 16:18:41 jkridner: is a board shipped to Indonesia too? May 14 16:18:46 praveendath92: cool to make the Android a display for a PC too! May 14 16:18:56 * DiegoTc wonders which was the status for the hardware request for bone101 May 14 16:19:49 Abhishek_: I think there was a delay in shipping yours because you had hardware initially to start development and just wanted a new board at some point during the project, no? May 14 16:19:50 @jkridner: yeah. My work is more kernel specific. May 14 16:19:51 jkridner, yes I feel good about hw May 14 16:20:02 I sent some cards from my side, and they should also be cleared now. May 14 16:20:06 DiegoTc, did you share the working hardware list with jkridner ? May 14 16:20:13 yes May 14 16:20:35 VoltVisionSteve, DiegoTc: is next week good for me to review the list and prepare to send out a care package? May 14 16:20:35 jkridner : All positive from my end. In good contact with both panto and alexanderhiam ! video will be out by tomorrow, sorry for the delay. Extremely busy with tomorrows exam! May 14 16:20:46 * jkridner is happy he at least sent a BBB to DiegoTc early. May 14 16:21:09 yes May 14 16:21:18 praveendath92: checked your plan, all looking good. Looking forward to see how it shapes ;). May 14 16:21:19 karki: no worries. videos aren't "due" until next week anyway. May 14 16:21:33 jkridner : what BBB pickup were you talking about at bangalore? May 14 16:21:41 jkridner, yes that sounds great. I am curious to discuss with you your opinions of the hardware...especially bluetooth and if we should do something with the TI sensor tag. May 14 16:21:41 has anyone published the video since last week? May 14 16:21:46 Cause I'm the only one from bangalore! May 14 16:21:49 * praveendath92 can wait for his board. May 14 16:21:59 karki: not sure, just saw an e-mail that someone was traveling and happened to be *visiting* Bangalore. May 14 16:22:08 vmayoral: Ya I put up my video. praveendath92 did too May 14 16:22:12 That's not me! May 14 16:22:18 can i get links? May 14 16:22:26 karki: if you live there, then you should be able to get a board pretty quick if you don't already have it. May 14 16:22:34 yeah that was disdi_ he was briefly at BLR, hehe May 14 16:22:44 * jkridner checks the latest videos on http://elinux.org/BeagleBoard/GSoC/2014_Projects May 14 16:22:46 rseethamraju: I saw yours today. It was good :) May 14 16:22:48 jkridner : I have my board! May 14 16:22:56 VoltVisionSteve: what are you thinking of with the sensortag? May 14 16:23:00 karki: ah, good. May 14 16:23:06 praveendath92: thanks! yours was good too! May 14 16:23:12 rseethamraju: a very good video! May 14 16:23:20 jkridner : Have you held my BBB for revision C ? May 14 16:23:44 * jkridner has already watched the videos from vmayoral, rseethamraju and praveendath92 May 14 16:23:50 karki: yes May 14 16:23:54 vmayoral: yeah. I'm excited. Mostly because of the target space of the project May 14 16:24:01 DiegoTc: thanks =) May 14 16:24:19 jkridner : Great! one more thing - would you be sending a couple of BB stickers along with the board? ;) May 14 16:24:19 rseethamraju: Thanks:) May 14 16:24:20 ds2: It is a low cost & portable Bluetooth sensor device which could be great to get people interested in Bluetooth projects of all kinds (even accelerometers on dancers!) May 14 16:24:40 * praveendath92 hates typing from mobile. May 14 16:24:49 praveendath92: indeed May 14 16:24:59 :) May 14 16:25:17 ds2: I think we could make some great tutorials using it and the BBB. May 14 16:25:26 VoltVisionSteve: thought you had something more concrete May 14 16:25:46 * jkridner double-checks on karki's question and isn't sure any longer May 14 16:26:39 I will be sending my video by the end of week......i was waiting for the HW so that it atleast shows up in the video May 14 16:27:09 * praveendath92 is afraid of running out of power May 14 16:27:17 is panto around? May 14 16:28:00 karki: I don't see an entry in the spreadsheet from panto May 14 16:28:53 disdi_ May 14 16:29:08 oops, was trying to search to make sure I heard from all of the students May 14 16:29:22 ds2: I would be glad to come up with 2-3 concrete examples if you guys like the concept of using the TI Sensor Tag to get people interested in Bluetooth. May 14 16:29:31 disdi_: at least joel_ is happy the hardware is on the way. May 14 16:29:53 jkridner : wait.... what does that mean ? no spreadsheet entry! now what? May 14 16:29:53 jkridner: yes May 14 16:30:03 VoltVisionSteve: ds2 is certainly a Bluetooth hacker May 14 16:30:19 <_av500_> oops, back May 14 16:30:23 <_av500_> internet cut out May 14 16:30:34 jkridner: I am almost dying to have my hands over it.....has been a lot of wait May 14 16:30:39 karki: it means I don't have your address and list of hardware needs. May 14 16:31:04 karki: get panto to provide. he should have the write permissions. May 14 16:31:25 Signing off. May 14 16:31:41 jkridner : okay! May 14 16:31:43 bye cdse... May 14 16:31:56 also, missing it for vmayoral May 14 16:32:16 so tridge hasn't provided an entry for hardware needs. May 14 16:32:47 * karki leaves the meeting. runs away to read data mining. May 14 16:33:01 bye cdsteinkuehler, will give you a link to the video later May 14 16:33:09 ok, I think that wraps up all the logistics headaches for now. let the technical fun discussions continue. May 14 16:33:18 * jkridner slams gavel May 14 16:33:26 wow...short mtg ;) May 14 16:33:33 jkridner: when are you traveling? May 14 16:33:38 tomorrow AM. May 14 16:35:12 * jkridner got a crapload of LED displays to try to make a big LED wall today (I know, last-last minute, so what can I expect), but I got the wrong screws. :( (silly me for ordering from a parts list without some personal verification.) May 14 16:35:24 what kind of screws do you need? May 14 16:35:38 I think M3. May 14 16:35:41 there is a place around here that can get you pretty much any screw you can think of May 14 16:35:48 getting a car? May 14 16:35:59 not getting a car I don't think. May 14 16:36:08 I'm staying at the Crowne Plaza. May 14 16:36:10 M3... OSH might have that May 14 16:36:19 trying to remember how far that is. May 14 16:36:28 Crowne has a shuttle during Sat/Sun May 14 16:36:42 I need the oval nuts for them too. https://www.adafruit.com/product/1158 May 14 16:37:22 this looks a little different... May 14 16:37:34 I was looking at https://learn.adafruit.com/adafruit-diy-led-video-wall/led-panel-prep and the M4 screws don't fit! May 14 16:37:38 Olanders is the place that has all sorts of fasteners you can think of May 14 16:37:47 they will sell in 1's or 100's May 14 16:38:14 jkridner: can you get someone from old National to give you a ride? that place is about 1-2 blocks down from NSC May 14 16:38:52 jkridner, VoltVisionSteve this is a small presention I did for the video: https://docs.google.com/presentation/d/1mqS1oaS3QBciLvLxTGhCsCb9fIClfpUENFpicchVEiA/edit?usp=sharing May 14 16:39:46 still trying to get things to work otherwise, I would be more helpful May 14 16:41:40 DiegoTc: do you have anything more visual to share to help people get the idea of what you'll be creating? May 14 16:41:53 yes, I will show an example running May 14 16:41:54 live May 14 16:41:57 on the video May 14 16:42:01 ds2: mechanical stuff is the bane of my exisitance. May 14 16:42:30 two leds will be running on the current mockup html. May 14 16:42:50 * vvu|Log nobody pinged me so far, so did not miss anything major :) May 14 16:42:54 DiegoTc: I think the idea of what the "tutorial platform" is is kinda lost. May 14 16:43:07 alexanderhiam: I changed sysfs.py to call _kernelFileIO should I make a new pull request? May 14 16:43:10 vvu|Log: go back to sleep. ;-p May 14 16:43:21 jkridner: that my run around yesterday - all mechanical May 14 16:43:23 just finished an exam...does not really work May 14 16:43:57 rseethamraju: sure May 14 16:44:02 jkridner what do you mean? May 14 16:44:59 I mean, it isn't clear that you plan to create an authoring tool, not just a way to pull in tutorials from gist.github.com. At least I thought that was the plan. May 14 16:46:50 I get you. I will change that. I will work with that and video today May 14 16:59:38 jkridner: the meeting is over? May 14 16:59:43 yes... May 14 16:59:49 meeting ends when I sound the gavel. May 14 16:59:56 tradition carried over from last year. May 14 17:03:50 jkridner: question, For next meeting we have to send the email to the GSOC list or its until the 28 of May? May 14 17:05:49 alexanderhiam: I made a pull request May 14 17:06:09 status report would be for 1 week in, so the next meeting after next week. May 14 17:06:24 rseethamraju: cool, I'll try to merge it later today May 14 17:06:39 but, you might have done something useful in the first 2 days of coding you'd like to share. May 14 17:06:55 DiegoTc: wouldn't hurt to send one next week. May 14 17:07:53 alexanderhiam: so agwatic’s stepper library with an example I can test that I have a H- bridge motor driver May 14 17:08:44 and a stepper motor I can get in clg I think so? May 14 17:08:56 ds2: did any work with BusPirate ? May 14 17:08:58 oh that would be great! It needs a bit of work, and I haven't had a chance to think about it May 14 17:09:05 clg? May 14 17:11:34 college May 14 17:11:47 oh ok May 14 17:12:26 I’ll borrow the stepper motor from them and I have a H bridge so May 14 17:12:39 awesome May 14 17:12:48 rseethamraju should stop saying so so many times May 14 17:13:18 wow epic fail how do you do that 3rd person thing? May 14 17:13:23 =) May 14 17:13:25 * alexanderhiam so hadn't noticed May 14 17:13:42 start with /me May 14 17:15:39 ok May 14 17:15:42 alexanderhiam : Doesn't PyBBIO already have a LCD display API? May 14 17:15:43 thanks May 14 17:16:13 karki_: it has an example for bitbanging a 2x10 character lcd May 14 17:16:34 whats bitbanging? May 14 17:17:05 * karki_ really hasn't looked into the various libraries supported by PyBBIO May 14 17:17:34 bitbanging = sotware implementation of serial protocols May 14 17:18:20 bitbanging => emulating various protocols on your everyday GPIO thru code May 14 17:18:51 ok May 14 17:18:54 karki_: https://github.com/alexanderhiam/PyBBIO/blob/master/examples/charLCD.py May 14 17:19:13 panto : jkridner was talking about some student hardware requirement form the mentors had to fill! May 14 17:19:56 actually, that probably doesn't work too well now that PyBBIO doesn't use mmap... May 14 17:20:34 :p May 14 17:21:12 I said I’d write one in the VIDEO. Didn’t notice. Thanks karki_ May 14 17:21:26 :O May 14 17:22:45 rseethamraju: that's just an example, a library would be nice May 14 17:22:53 karki_, link? May 14 17:23:13 vvu|Log: nope May 14 17:23:30 alexanderhiam: good =) May 14 17:23:47 panto : I'm afraid I don't have it with me right now! It's with cathy, jkridner May 14 17:24:07 jkridner : link please :) May 14 17:24:08 so I’m going through the code to see if I can use kernelFilmenameIO May 14 17:24:53 panto: it's the 'GSoC Hardware' doc jkridner shared on google drive May 14 17:24:57 and I’ll try the stepper library next May 14 17:25:10 alexanderhiam : why does python file IO work slowly? Is it not itself a C implementation internally? May 14 17:25:24 rseethamraju: sounds good May 14 17:25:54 karki-: becasue Python likes everything to be big objects May 14 17:26:43 when it opens the file it creates a fancy File object May 14 17:27:24 which adds a lot of overhead to provide functionality we don't care about when just writing a single line to a file then closing it May 14 17:27:34 makes sense! May 14 17:29:26 no work on bbio-server this time? May 14 17:30:38 Ya the plan is to make it work with the camera May 14 17:31:13 like a Page.addVideoStream() method May 14 17:31:49 ds2: my dad has some broken samsung LCDs who have their edid hex screwed up and wants to use bus pirate to fix them. May 14 17:37:50 vvu|Log: oh...that should be easy... it is I2C @ 5V May 14 17:38:28 vvu|Log: you could use an arduino instead May 14 17:38:45 you can probally hack up the BB with a level converter May 14 17:38:52 indeed May 14 17:38:57 EDID is just I2C rom at an odd address May 14 17:39:10 oh yeah...that works too :D May 14 17:45:38 rendering May 14 18:27:37 Abhishek_: my dad needs smth really plain easy to use, i'm not home to help him May 14 18:42:14 vvu|Log: if your dad uses Windows, you might give him this link to try: http://blog.komeil.com/2008/06/fixing-edid-dvi-monitors-no-signal.html May 14 18:44:59 oh, it won't work as it needs a license, never mind May 14 18:46:06 Abhishek_: he knows a bit how to do it with buspirate May 14 21:32:07 mranostay: What was the remoteproc bug you were talking about yesterday with PRU0? May 15 02:12:44 hi VoltVisionSteve May 15 02:12:48 hi vmayoral May 15 02:13:27 hello DiegoTc ! May 15 02:13:54 VoltVisionSteve, could you do me a favor? May 15 02:15:23 DiegoTc, can I do it on a phone? May 15 02:15:34 mmm, I think May 15 02:15:41 could you search for Honduras in google May 15 02:15:48 and send me a screenshot May 15 02:16:12 DiegoTc, of the entire country in google maps? May 15 02:16:19 nop in google search May 15 02:16:45 is that illegal? May 15 02:16:53 haha nop May 15 02:17:19 just need to know the results in another country May 15 02:17:31 ok, just did it, should I email you a jpg? May 15 02:17:37 yeap May 15 02:17:40 thanks :) May 15 02:17:54 no problem! Talk soon... May 15 02:18:57 DiegoTc, I pasted it into the email...lemme know if that works... May 15 02:19:58 got it May 15 02:20:00 thanks May 15 02:21:38 Does it look different? May 15 02:22:28 the results nop, Just in english May 15 02:24:04 DiegoTc, good night. Lemme know if you want to talk tomorrow. I'll be here @ the office Thu but not Fri. Talk soon! **** ENDING LOGGING AT Thu May 15 02:59:59 2014
