**** BEGIN LOGGING AT Fri Dec 28 02:59:58 2018 Dec 28 03:05:04 Oh. You have nice handwriting, no offense. Dec 28 03:05:27 w... why would I take offense to a compliment on my handwriting? Dec 28 03:05:32 I got you. Dec 28 03:05:38 Why? I will tell you. Dec 28 03:05:57 B/c, handwriting is so 20th century. Dec 28 03:05:58 ... Dec 28 03:06:00 Just kidding. Dec 28 03:06:25 zmatt: I was just goofing w/ you. Dec 28 03:06:42 I saw what you were describing. i will review it again. Dec 28 03:07:58 I did put some effort into attempting to write legibly Dec 28 03:09:50 I saw that. Dec 28 03:12:57 So, the LiPo actually powers the motor drivers (H-bridges). Dec 28 03:13:03 Just like you said. **** BEGIN LOGGING AT Fri Dec 28 03:14:53 2018 Dec 28 03:15:22 you mean the big box that says "charger" that takes power from the 12V and sticks it into the lipo? :P Dec 28 03:15:32 Yep! Dec 28 03:15:57 That old box, charger, keeps the LiPo charged on "long" trips. Dec 28 03:16:21 That is actually nice, esp. if there is actual AC around. Dec 28 03:17:27 The thing, ideas, that caused me to believe this was a fact was all related to working w/ the BBBlue and seeing those LEDs for the first time. Dec 28 03:17:28 ... Dec 28 03:17:34 tip: make sure the motor drivers and servo supply aren't used when you're charging the lipo, otherwise the charger will undoubtedly get confused as fuck Dec 28 03:17:47 I had been used to using it for other purposes. Dec 28 03:17:49 Okay. Dec 28 03:18:06 I saw that earlier, too. Dec 28 03:18:30 It was only charging at times. Dec 28 03:18:43 I considered drawing the green led that's connected to the charger Dec 28 03:18:57 I saw that chrg LED too. Dec 28 03:19:34 Oh and I did see the breakdown of the +, -, and (0) on the servo rail. Dec 28 03:19:50 like I said earlier, the battery level indicator leds are software-controlled, so you can use them as a (probably very inaccurate) battery level indication, or you can use the leds for other things if you want Dec 28 03:20:07 It got by me at first. Dec 28 03:20:14 + - and a pulse-shaped line Dec 28 03:20:19 Okay. That it cool. I will check that out. Dec 28 03:20:46 (and iirc there was a testpoint sitting in between being visually distracting) Dec 28 03:21:16 zmatt: Is that pulse-shaped line a connector of some sort for soldering? Dec 28 03:22:00 it just to label the "signal" pin of the servo line (since servos are controlled by a pwm signal of sorts) Dec 28 03:22:10 of the servo connector Dec 28 03:22:10 Oh. Okay. Dec 28 03:22:58 I figured it was a "easter egg," i.e. so to say. Dec 28 03:23:47 ?? Dec 28 03:23:59 I am actually glad now that I invested in some connectors for the BBBlue. Dec 28 03:24:03 I got them about a year back. Dec 28 03:24:14 Oh nothing. Forget the "easter egg" idea. Dec 28 03:25:04 Now, I just need to solder them to some old motors and go, go, go. Dec 28 03:26:01 zmatt: Do you know about this idea --> https://markayoder.github.io/PRUCookbook/01case/case.html#_robotics_control_library? Dec 28 03:26:42 There are some missing header files that I have been unable to find. I was going to try out some PRU stuff for that library to learn PRU stuff. Dec 28 03:27:05 what "idea" are you referring to? Dec 28 03:27:12 I got the TRM out and started but dang it. Dec 28 03:27:14 Oh... Dec 28 03:27:22 PWM! Dec 28 03:27:26 for motors. Dec 28 03:27:28 that the servo outputs are pru pins? I mentioned that often enough Dec 28 03:27:41 Oh. I will look back. Dec 28 03:28:00 Do not fret. I have look back tech. via mIRC. Dec 28 03:28:34 or wait until it happens again. Dec 28 03:28:39 e.g. Dec 28 03:28:41 2018-12-23.log.bz2:22:23:30 < zmatt> rar_rar: the "servo" outputs are 3.3v digital outputs that can produce pretty much any kind of control signal given the appropriate pru firmware. Dec 28 03:29:00 Oh. Dec 28 03:30:31 Okay. So, the pru stuff is already done. Got it. Dec 28 03:30:31 that webpage is a nice overview of pru applications though Dec 28 03:30:50 I saw that stuff for the BBB and I thought good idea. Dec 28 03:31:05 well, librobotcontrol includes simple pru firmware to use those pins as servo outputs Dec 28 03:31:15 Oh. I got why it was so easy. Dec 28 03:31:29 the pru firmware was already typed up. Dec 28 03:31:38 if you want to create custom signals, custom pru firmware would be required Dec 28 03:32:08 Oh and the TI site is not able to be commented on any longer. Is the pru part of their site old news? Dec 28 03:32:25 which part of their site are you referring to? Dec 28 03:32:31 Please hold. Dec 28 03:32:34 I will get the link. Dec 28 03:33:09 http://processors.wiki.ti.com/index.php/PRU_Projects is like an old dust bin or something. Dec 28 03:33:24 Trying to keep things current is very difficult. Dec 28 03:33:52 yeah for some reason they killed their wiki... I mean, it's still up but more or less read-only Dec 28 03:34:52 Right. I am not sure why. Too many people, too many projects. Most likely. Dec 28 03:40:36 jkridner[m]: do you happen to know why TI killed the processors wiki? **** BEGIN LOGGING AT Fri Dec 28 05:26:53 2018 **** BEGIN LOGGING AT Fri Dec 28 05:34:10 2018 Dec 28 06:47:15 i'd like to set gpio 1_27 to high in an overlay if possible. Any idea how to do this? Dec 28 06:47:30 I'd also be happy just to test doing it from the command line Dec 28 06:47:40 I want to enable the crystal Dec 28 07:31:52 JOIN Dec 28 07:32:06 I want to contribute to the organisation.My skills set include HTML,CSS,PHP,Mysql,Ruby,JAVASCRIPT,BOOTSTRAP,JQUERY,ANGULAR JS and C++,C, node js, python, java, and experience in android development Created my own messenger like whatsapp and fb mixed completed codefundo Microsoft challange and many more please help how can i contribute am interested in contributing to this Organization, so I reached out to you! I'm participating in Dec 28 07:43:36 patience, that's missing Dec 28 10:15:02 man i love the BBB Dec 28 10:15:14 it's such a great board for so many purposes Dec 28 10:15:19 https://pbs.twimg.com/media/Dvc9TuKV4AAZjwa.jpg Dec 28 10:15:37 i haev the GPIOs hooked up to logic lvl translators + shift registers for reading parallel dial output Dec 28 10:15:39 works like a charm Dec 28 16:34:03 kremlin: why a shift register? not enough gpios? Dec 28 18:18:02 zmatt: exactly Dec 28 18:52:11 that's a lot of gpios Dec 28 18:53:20 the killers are the dials that have like 14 input options each Dec 28 18:55:21 also i'm through farting around with these bush league breadboard mess Dec 28 18:55:25 https://imgur.com/a/ezitGKZ Dec 28 18:55:31 i bet you can imagine what this does Dec 28 18:59:12 you said you had gpios hooked up to level shifters, so maybe they are level shifters? I certainly wouldn't be able to imagine what it does based on the images alone Dec 28 18:59:18 :P Dec 28 19:00:25 level shifters + shift register Dec 28 19:00:35 pulldowns for the inputs too Dec 29 00:59:50 Fri. fun day!
