**** BEGIN LOGGING AT Sun Dec 23 03:00:00 2018 Dec 23 03:21:05 i have a 64 gb sd card and the bbb just rand out of spac how is that possibel? Dec 23 03:21:09 possible? Dec 23 03:22:41 ant__: Look here on how to manage your space ----> https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Expanding_File_System_Partition_On_A_microSD. Dec 23 03:23:33 brb Dec 23 10:23:02 ah rcn has a script for it, didn't know that but makes sense Dec 23 20:33:33 Is anyone here that wants to view some software for the LoadCape and comment on it? Dec 23 20:34:20 I have been beating myself up, back issues, trying to get two motors working simultaneously. Dec 23 20:35:07 It is just GPIO and a library in Python. I still cannot get it cracked. Dec 23 20:36:39 https://beagleboard.org/discuss#board_forum_embed?place=msg%2Fbeagleboard%2F2b2rDQMqVbw%2FJ-wuy5neAgAJ if you get bored. Dec 23 20:39:17 Oh and I know. It is messed up. Dec 23 20:46:04 https://github.com/silver2row/loadcape is the changes from that earlier post. Please send guidance/rations. Dec 23 20:46:21 I will make a pastebin paste soon. Dec 23 20:53:04 https://pastebin.com/a6sGYDad is the library for this software ---> https://pastebin.com/Ub49eEAg Dec 23 21:15:47 Quick question about connecting ESCs for brushless motors to the beaglebone blue. Do I connect the ESCs to one of the eight servomotor conectors? From the ESCs to the bbone are just two wires, white and black. Dec 23 21:20:34 I have no clue. I tried to figure that out a while ago. You might want to wait around for someone to show up. Dec 23 21:21:24 Hi set_. I've been offline for a while. Weren't you working with using the beaglebone blue to do some drone thing? How'd that go? Dec 23 21:21:53 Not well. I figured I could set up the ESCs easily. Dec 23 21:22:35 Plus the idea behind what I was working on erupted into nothingness. I guess the people working on the project left me in the dust. Dec 23 21:23:15 Well, if I figure it out - I'll let you know. Dec 23 21:23:30 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. I'm not familiar with the software stack though, so I have no idea what capabilities are currently provided by librobotcontrol and its pru firmware Dec 23 21:24:19 Thank you. That would be nice. Dec 23 21:25:38 Zmatt: thanks. Dec 23 21:37:07 set_: I'm guessing black on the ESC is ground and goes to the ground pin of the servo pins (closest to center). The white is signal and goes to (-) pin (closest to edge) of the servo pins. So I'll start working from that. Dec 23 21:37:54 the esc has no documentation? guessing the purpose of wires based on color sounds iffy to me Dec 23 21:39:51 Usually in ESCs, I am guessing now, the Black lead is not GND but you can test that. Dec 23 21:39:56 Do you have a multi-meter? Dec 23 21:40:26 set_: yes Dec 23 21:40:54 Usually wiring w/ only black and white has the BLACK as LIVE. Dec 23 21:41:26 Well. Add power and test that mother. Did sound enthusiastic enough? Dec 23 21:41:41 Did sound = did that sound. Dec 23 21:41:43 Sorry. Dec 23 21:45:56 That is actually something I did not do w/ the ESCs. I should have tested their leads. I had four leads outside of the black and white wires on my ESCs. Dec 23 21:47:24 brb Dec 23 21:47:44 zmatt: Yep the ESCs came without documentation and I can't find anything online for them, but the white wire has a "S" and the black wire has a "-" Dec 23 21:48:18 rar_rar: I guess makes sense to be "signal" and "ground" then Dec 23 21:48:40 and hopefully there's some kind of signal standard that everyone implicitly follows (I really don't know anything about RC) Dec 23 21:53:34 bbl. I am glad you two figured it out. I am off to the store. Dec 23 21:55:27 White=signal and black=ground seems to be a standard for ESCs in the various things I've read about them. Dec 23 21:56:00 rar_rar: it makes sense for ESC to skip the +6V wire since they use their own power source anyway Dec 23 22:10:33 Humpelst1lzchen: Yep - For each ESC I've got two wires for power from the 2S LiPo, 3 wires going to the motor. So we'll see what happens. Pretty nervous since this is my first beaglebone build. Dec 23 22:11:17 rar_rar: the three wires to the motor are a completely different story Dec 23 22:11:36 rar_rar: did you solder the adapter cable yet? Dec 23 22:16:55 I soldered 3 (m) bullet connectors to the three ESC motor wires and soldered 3 (f) bullet connectors to the three motors wires and then connected them. I don't know what you mean by an "adaper cable" Dec 23 22:19:13 rar_rar: from the 3 pin on the blue to the 2 pin of your ESC Dec 23 22:20:56 The 2 pin? The only pins I have on the ESC are A,B,C (motor), +,- (Power) and (S,-) which I'm assuming are signal and ground. Dec 23 22:22:16 rar_rar: If your ESC is really signal | gnd then you obviously need an adapter to the blue which is signal | +6V | gnd Dec 23 22:26:04 If you are talking about the servo motor connectors on the blue I have a soldered connection to the ESC and a black push-style J-connector to the blue Dec 23 22:33:09 Well I fired it up. Nothing's smoking. Motors went "beep" Dec 23 22:35:00 That is as far as I got. Dec 23 22:35:09 "beep" Dec 23 22:35:45 I thought it was the receiver. Dec 23 22:37:15 Are you using librotbotcontrol? Dec 23 22:37:30 rc_test_servos -c 1 -e .5 gives "ERROR: PRU servo Controller not initialized" ... so I guess I'll do some more reading Dec 23 22:37:58 rar_rar: Are you using the latest image? Dec 23 22:38:19 from that bbb.io/latest-images site? Dec 23 22:38:45 There is a prompt that comes up when booting for initial set up of librobotcontrol. Dec 23 22:43:34 set_: Apparently not using the latest image. Was using the 9.3-iot from 2018-03-05. I'll download the one from Oct and see. Dec 23 22:43:57 Yea. There is some updated items that may be useful. Dec 23 22:44:25 I think that blue link is the "flagship" of images so far. At least...that is the buzz. Dec 23 22:50:42 downloaded and reflashing soon Dec 23 22:53:42 Okay. When that link for the librobotcontrol pops up on the terminal, think about it and read it. Dec 23 22:53:44 Serious. Dec 23 22:53:55 There are some various options for it. Dec 23 23:51:48 Ah back in the saddle - yes there are more options for testing. Found a typo in rc_test_escs Dec 23 23:59:25 Oh. Dec 23 23:59:38 Dang, that took a lifetime. Welcome back. Dec 24 01:11:42 Thanks - the first imaging failed so I had to re-image the SD card. I got the "ERROR: pru-rproc driver not loaded" error am now just waiting for the leds to stop flashing in the "Flashing the Built-In eMMC Storage" process. Does it usually take long to flash? Dec 24 01:17:00 No...not that long. 15 to 25 mins. Dec 24 01:17:07 You have what board? Dec 24 01:17:09 BBBlue? Dec 24 01:20:30 Oh...zmatt once told me something about the eMMC and how burning an image to it would benefit the user b/c the bootloader may be out of date. Dec 24 01:20:44 It takes longer than his work around but it is done and done. Dec 24 01:21:51 Sometimes, the bootloader is not updated on the eMMC and the eMMC bootloader takes charge of the process, e.g. even if you are using an SD Card. Dec 24 01:22:07 Zoinks. Dec 24 01:22:38 Finally! I have the BBBlue. Dec 24 01:23:18 Oh. Dec 24 01:23:20 Okay. Dec 24 01:23:35 Oh, I got you. BBBlue! Dec 24 01:23:47 Hey. did you read what I typed out? Dec 24 01:24:56 Yes - when I ran rc_test_drivers it gave me the error that indicated I also had to flash the boot loader even if booting from SD card. Dec 24 01:25:49 Now that the boot loader flash is done, I've booted again from the SD card and all checks have passed. Dec 24 01:27:33 Yea! Dec 24 01:27:43 Coolness. Dec 24 01:28:45 But, please remember! The eMMC issue overrides the SD Card image w/ respects to the bootloader, e.g. if you still have an image on your eMMC. Dec 24 01:32:50 Understood. That's why I suppose I had to update both SD card and bootloader. Well, rc_test_escs seems generate no errors with no power to motors. I guess I'll try with the motor powered up too. Dec 24 01:33:29 Yea! Dec 24 01:33:47 Oops. Dang. Dec 24 01:34:09 No power, no fun. Dec 24 01:38:27 Well - with power I get no errors, but no spinning motors either. I guess I'll have to look into what rc_test_escs actually does. Got to go for the evening though. I'll hopefully have more news later. Dec 24 01:39:43 Okay. Dec 24 01:39:59 rar_rar: Maybe I will get my BBBlue out too. Two heads are better than one. Dec 24 01:40:08 I have been using the LoadCape lately and trying things. Dec 24 01:40:17 Sorry for today. Dec 24 02:00:35 did anyone see those instructions for my LoadCape in the paste? **** ENDING LOGGING AT Mon Dec 24 02:59:59 2018
