**** BEGIN LOGGING AT Sat Feb 08 02:59:58 2020 Feb 08 03:11:56 zmatt reminds me I need to finish my SPI code ... Feb 08 03:15:02 I know I am a bit weird when I just realized I wrote 1200 lines of code just to test the SPI port... Feb 08 03:15:17 seems a bit much Feb 08 03:17:18 I once did a test of spi on the bbx15, using pru as a trivial spi slave for verifying data integrity: https://github.com/mvduin/py-uio/blob/master/pru-examples/fw/bbx15-spi-test.pasm Feb 08 03:18:21 It all does something but ... it's too much JUST to test the SPI port. I tend to go over board. Huh ... now that is something I didn't think of. Feb 08 03:19:57 nothing goes to waste... maybe to waist though. Feb 08 03:22:21 thanks that might work... I am so use to BFI that having to set pins up with config-pin seemed weird. (BFI Brute Force and Ignorant) Feb 08 03:22:47 iirc this test was wrong though, and it looks like I never committed a fix. iirc, at the 24 MHz bitrate I used the roundtrip signal delay caused the received data to be 1 bit delayed compared to what it should be, and my test actually expects this, hence it breaks at lower speeds Feb 08 03:22:57 I should verify and fix that Feb 08 03:28:55 heh :D Feb 08 03:37:11 it should either just use lower speeds, or have pru update its output immediately after sampling its input after the rising clock edge, which is technically wrong/non-standard but works fine in practice since the sck in -> miso out delay would stlil be way bigger than McSPI's hold time requirement Feb 08 03:42:43 Otay! Feb 08 03:44:41 I got to "segmentation fault" again as an error. Feb 08 03:44:45 Well, that is something. Feb 08 03:44:58 congrats, you did something wrong Feb 08 03:45:05 Right. Feb 08 04:12:51 no ... nevermind Feb 08 04:17:55 GenTooMan: ? Feb 08 13:24:44 hi there channel :-) Feb 08 13:31:46 got rev a5c. and c. Is there a way to build a more powerful computer. Putting or connecting both boards together? Feb 08 13:32:51 and make one whole system!! Feb 08 13:32:52 by using both boards, at the very least you'll get more power consumption... is that what you meant? :) Feb 08 13:38:28 zmatt, of course it will consume more power but , I mean using both boards as a one system.. is it clear? Feb 08 13:39:08 mmmm... I don't how to explain.... Feb 08 13:39:35 I don't know how to explain... sorry Feb 08 13:39:49 mmm... Feb 08 13:40:08 be back in a while lunch time Feb 08 13:40:14 I was just being silly. the answer is no, except in very application-specific situations Feb 08 13:40:43 like what ? Feb 08 13:40:59 as in, you could have two beaglebones be part of one product/device, each doing its own specific sub-task Feb 08 13:41:39 but it would still be two separate linux systems working together in some way, not one system Feb 08 13:42:04 right I see znatt Feb 08 14:57:18 hi guys Feb 08 15:33:53 zmatt, are you there? Feb 08 15:41:46 any interesting new capes for bbb? Feb 08 15:45:43 any project that have two beaglebones be part of one product/device, each doing its own specific sub-task? Feb 08 15:48:57 hi there Kejau, how's things with you? hope pretty well though Feb 08 21:01:31 cisco Feb 08 21:01:38 er Feb 09 01:34:16 Well, the gripper is in "motion." Feb 09 01:35:32 The item is not working yet b/c: a: The servo needs to be put at a particular degree with the gripper and b: I do not know the angle in which this gripper needs to have the servo at what degree. Feb 09 01:35:33 ... Feb 09 01:35:45 So, yea. A lot of work w/ more trial and error. Feb 09 01:40:45 I guess 180 degrees fully opened is the first trial. Feb 09 02:05:58 GenTooMan: Are you here? Feb 09 02:06:27 What would be some reasons why my servo would be getting hot? Feb 09 02:16:11 I read every idea already. Here is my source to test: https://pastebin.com/EziBKSZJ. This is to bring my motor to angle 10 and 170. Feb 09 02:17:29 I took the Gripper off to just test the servo to see if the Gripper was at fault. It is not the Gripper. Feb 09 02:36:00 NEvermind. The servo is on backwards and things got iffy. Feb 09 02:46:46 0 = 180 and vice versa. Sorry. Feb 09 02:51:12 Your servo would get hot if it was stopped while rotating or could not rotate any further mechanically speaking. You should read the servo's specs carefully to know the maximum angle range it can rotate. Feb 09 02:51:29 Okay. Feb 09 02:52:35 If there is a lot of mechanical resistance the servo won't move well. If it CAN'T move it will constantly be drawing power and start to warm up steadily. Feb 09 02:53:39 Right. That is probably what happened. Feb 09 02:53:53 I was using the USB connect instead of the 12v battery. Feb 09 02:54:03 But, I was just running the single servo. Feb 09 02:54:56 I think the Gripper is too heavy for this standard servo. Feb 09 02:55:41 It has all sorts of hardware on it, e.g. ABS, nuts and bolts, and more plastic plus gears. Feb 09 02:55:55 A waste so far. Feb 09 02:58:55 Depending on how the device is set up will depend on what you need to do to analyse what you gripper is or is not doing correctly. **** ENDING LOGGING AT Sun Feb 09 02:59:57 2020
