**** BEGIN LOGGING AT Sun Aug 13 03:00:00 2017 Aug 13 10:31:41 hello Aug 13 10:31:55 hi Aug 13 10:32:46 i have an ESC that i'm looking to supply power to: https://www.banggood.com/Racerstar-RS20Ax4-V2-20A-BB2-48MHz-Blheli_S-2-4S-Opto-Oneshot42-Multishot-4-in-1-ESC-for-FPV-Racer-p-1080541.html Aug 13 10:32:56 it's rated to have an input of 2-4S Aug 13 10:33:17 i can power it through an external power supply at 7.4V which is great Aug 13 10:33:27 now i'm looking to power it through the BBB Aug 13 10:34:12 as far as i can tell, my options are 1. Use the +/- servo pins, 2. Use the 5V power out, 3. Somehow connect directly to the LIPO Aug 13 10:34:46 #1 didn't work because the servo pins only go up to 6V per the schematic, and I've verified with my power supply that the ESC doesn't operate with that voltage Aug 13 10:35:17 (it's a 6V reg) Aug 13 10:35:26 #2 i assume won't work for the same reason. Aug 13 10:35:52 #3 seems to be my only option, but it's unclear how where I should make the connection closer to the battery Aug 13 10:36:21 i suppose there's a fourth option, which is getting another ESC altogether that operates at a different voltage (ideally 6V like the servo output pin) Aug 13 10:44:45 that sounds for me more like something you solve with a 2nd energysource and a mosfet Aug 13 10:45:24 you use the mosfet to activate and deactivate the 2nd energysource Aug 13 10:46:03 oh, interesting. that would make me sad to do though. i love how the BBB has a built-in LIPO charger. Aug 13 10:46:31 so i'd really prefer relying entirely on the single LIPO battery that can be charged through the BBB's barrel jack Aug 13 10:46:40 any other ideas? Aug 13 10:47:28 what's the power draw of this thing? Aug 13 10:48:45 i'm actually not too certain. i saw steady state of a couple amps going through the 4-in-1 ESC to power 4 motors. Aug 13 10:48:51 but, there are probably spikes that go much higher Aug 13 10:49:14 are you worried about the ESC competing with power to the main board? Aug 13 10:52:47 lol, that would instantly vaporise tracks on the BBB Aug 13 10:54:11 PRU - I've installed a new Debian - how do I install the PRU libraries? Aug 13 10:54:32 .. on BeagleBone Black Aug 13 11:05:31 tbr: so no hope? best take the suggestion to use a separate power source? Aug 13 11:06:41 braincore: if it needs 6V minimum, then you'll need something like 2 cells in series (or a serious step up converter) Aug 13 15:20:58 Peter_L: I think apt install pru-software-support-package Aug 13 15:21:03 maybe Aug 13 21:06:30 hello Aug 13 21:06:39 i cant get my wifi work on debian Aug 13 21:06:47 well, i can, but not automatically Aug 13 21:07:04 i put a very simple config in /network/interfaces Aug 13 21:07:26 and i figured out i need a /etc/wpa_suppliant.conf as well Aug 13 21:07:45 however, after reboot, i need to login through the console Aug 13 21:08:21 kill wpa_supplicant Aug 13 21:08:30 and invoke ifup wlan0 Aug 13 21:09:00 I could of course put these steps in a startup script or sth Aug 13 21:09:14 but I have the feeling this should work automatically Aug 13 21:09:20 any hints, anyone? Aug 13 21:11:24 ah wrong Aug 13 21:11:32 wpa_supplicant is not necessary Aug 13 21:11:38 i already removed it Aug 13 21:12:05 its only the simple config (ssid and psk) in /etc/network/interfaces Aug 13 21:18:28 !idle Aug 13 21:19:04 sweet! using a FET + servo output on BB Blue, i am able to drive neato lidar dc motor under software speed control Aug 13 21:20:41 inte: this maybe https://github.com/beagleboard/beaglebone-blue/wiki/Frequently-Asked-Questions-(FAQ) Aug 13 21:24:46 MrCurious: oh, does that mean i needn`t have to edit the config files manually? Aug 13 21:24:49 thats nice Aug 13 21:25:13 but this wiki is for the blue, while i have the black Aug 13 21:25:20 hope that doesnt matter Aug 13 21:26:12 .oO(testing...) Aug 13 21:28:39 mh Aug 13 21:28:45 cant find connmanctl Aug 13 21:28:56 wups sorry found Aug 13 21:32:06 did it work? Aug 13 21:32:23 root@beaglebone:/home/debian# connmanctl scan wifi Aug 13 21:32:24 Error /net/connman/technology/wifi: Not supported Aug 13 21:32:34 :( Aug 13 21:32:35 currently rebooting Aug 13 21:32:43 maybe i messed something up Aug 13 21:34:45 wow Aug 13 21:34:50 hell, yeah Aug 13 21:35:07 rebooting again to see if its still there Aug 13 21:36:24 mh, i just realized i invoke those commands as normal user Aug 13 21:38:55 ok it was gone after reboot Aug 13 21:40:36 great Aug 13 21:40:43 now its not working anymore Aug 13 21:40:47 on the blue, it persists across boots Aug 13 21:42:28 funny enough, i just unpluged the usb wifi stick Aug 13 21:42:31 replugged it Aug 13 21:42:35 and it worked again Aug 13 21:43:39 probably a network restart would also help Aug 13 21:43:56 so its more or less the same behavior as with my handwritten config Aug 13 21:44:00 damned Aug 13 21:44:36 oh, no, now it worked Aug 13 21:44:51 im totally confused now but anyways, thanks for the hint Aug 13 21:45:42 i missunderstood those instructions (they are also in /etc/networking/interfaces) and uncommented them there :) Aug 13 21:45:44 lol Aug 13 21:46:40 anyways, there is one more thing Aug 13 21:47:37 when i flash through uncommenting the last line in /boot/uEnv.txt Aug 13 21:47:51 how do I determine when flashing has finished? Aug 13 21:48:35 my beagle ends up in a flashing loop Aug 13 21:49:06 sorry, i am a noob, just had that wifi page open, thought i would share Aug 13 21:49:24 and of course, the leds sometimes change, but the last time i pulled out the sd card it was obviously the wrong moment and i had to try again Aug 13 21:49:28 and again... Aug 13 21:49:38 oh ok dont worry you helped me a lot! Aug 13 21:49:44 in either case:) Aug 13 22:08:39 Hello...what is a console image from http://elinux.org/Beagleboard:BeagleBoneBlack_Debian? Aug 13 22:09:01 I do get for what reasons we have a console image... Aug 13 22:43:11 For instance, is it so I can add what I chose instead of already having a GUI and Cloud9 and/or bonescript? Aug 13 22:52:21 Are there "cable kits" for the beaglebone Blue anywhere? I realized what I'm about to do here is order some stuff from digikey, some stuff from hobbyking, some stuff from pololu, and then try to kit it up into baggies of "one blue worth of crap" Aug 13 22:52:45 and then I thought: Maybe someone has already done that! But nothing shows up on Tindie and I'm not sure where else to look. Aug 13 22:53:28 i ordered cables off ebay from china Aug 13 23:11:10 Up, up, and OTAY! Aug 14 01:30:58 Yup, I can get 'em all from ebay. Just some I want 10 of so that consumes a whole pack, and others I only need 1 of so a pack of 10 is overkill. hmm. Aug 14 01:30:59 woo hoo. 3 sets of cables for neato lidars for BB Blue made Aug 14 01:31:17 you're playing with neatos too? Aug 14 01:31:50 yes. will run ROS on BB Blue and a bigger intel to do the slam Aug 14 01:32:22 kinda blows my mind that the OEM controller does competent SLAM on such a lightweight chip Aug 14 01:32:58 though having owned an XV-11 since it came out, perhaps "competent" is being a bit charitable ;) Aug 14 01:32:59 wont be able to do slam on BB for the other sensors i have Aug 14 02:39:59 anyone with experience running arducopter on the BBB? Aug 14 02:40:18 i'm getting an error "No INS backends" Aug 14 02:40:21 BBB is ambigous… Blue or Black Aug 14 02:40:32 oh it is?! funny, i thought the third B was Blue Aug 14 02:40:37 BBB Blue Aug 14 02:40:50 BB Blue :) Aug 14 02:41:04 OH silly omg Aug 14 02:41:09 haha Aug 14 02:41:42 you may have to edit the /boot/uEnv.txt and add Aug 14 02:41:42 dtb=am335x-boneblue.dtb Aug 14 02:41:58 i had to do that with mine to make all serial ports visible Aug 14 02:42:34 mine currently has "dtb=am335x-boneblue-ArduPilot.dtb" Aug 14 02:42:38 do you know if yours is correct, or mine? Aug 14 02:42:54 i got mine from: http://dronerai.de/2017/04/30/install-ardupilot-on-beaglebone-blue/#comment-14 Aug 14 02:43:43 i havent run arducopter Aug 14 02:44:31 I see, I just checked: ls /boot/dtbs/4.4.80-ti-rt-r116/ Aug 14 02:44:34 both exist Aug 14 02:44:36 what are dtb files? Aug 14 02:44:49 (i'll google it) Aug 14 02:45:52 i think they specify the mappings between pins and functions **** ENDING LOGGING AT Mon Aug 14 03:00:01 2017
