**** BEGIN LOGGING AT Sat Jan 30 02:59:57 2021 Jan 30 03:01:51 For some reason, the frequency was too high in the source. Scratch everything I stated. Oops. Jan 30 03:02:20 * set_ goes back to corner Jan 30 03:22:45 My elevator goes to 12" and back to zero w/ buzzers! Jan 30 03:22:59 Yea boy! Jan 30 03:24:00 sorry. I was wrong. Jan 30 03:24:04 Python made me a liar. Jan 30 03:28:22 Well...something is wrong. Jan 30 03:28:39 "Ain't it me chattin' to maself he?" Jan 30 03:28:47 Pobably. Jan 30 03:36:47 Anyway...enough spoofs for one night. Back to the grind. Jan 30 03:37:20 Two work, two do not. Help! Jan 30 03:37:34 Oh! Jan 30 03:38:33 Do I need to use the Cape Compatibility Layer for the MotorCape and BBBW? Jan 30 03:44:52 EERPOM changed? Jan 30 03:45:00 Dang it. EEPROM? Jan 30 03:47:04 Off to check! Jan 30 03:54:32 Well dang. Jan 30 03:54:59 It seems only one of my L298 onboard the MotorCape are working. Jan 30 03:56:10 Come on, guys? It is me! Send rations! Jan 30 03:58:03 10:00! Jan 30 03:58:04 No! Jan 30 04:46:26 maybe! Jan 30 04:47:23 perhaps you should replace the L298 or see if the control signals are Otay. Jan 30 04:50:58 GenTooMan: You made it! Jan 30 04:51:09 Otay! Jan 30 04:51:11 Trying now. Jan 30 04:54:46 Okay. So, my power is lit up. Good. Check. Whatever. Jan 30 04:54:59 The source does not require errors to tell me that it is faulty. Jan 30 04:55:01 Check. Jan 30 04:55:10 It works. Jan 30 04:55:36 Now, my LEDs are out on the right side of the board and I get no motor movement on Motor 3 && 4. Jan 30 04:55:42 So, it is testing time. Jan 30 04:55:46 Please be patient. Jan 30 04:58:00 hook the output of the device to your multi meter, set it to say 20VDC and watch to see if the voltage changes when going one direction. When reversing the direction the polarity of the voltage should switch as well. Jan 30 04:58:26 Thank you. Okay. Jan 30 05:00:41 0v Jan 30 05:01:03 WHen I run the source and go high, the reading is 0v. Jan 30 05:01:12 No led, no motor movement. Jan 30 05:02:13 are there any fuses on the board? Jan 30 05:02:47 MotorCape. No, I am not aware of one. Jan 30 05:03:11 At least, not from my perspective. Let me check the schematic. Jan 30 05:05:18 I see nothing in the form of a fuse. Jan 30 05:05:43 diodes, resistors, and a cap. Jan 30 05:06:14 and then something that states U1 - Uxx. Jan 30 05:06:57 and you have power going to the board I assume? Jan 30 05:07:33 Yes sir. I have a 12v to the Cape, a Barrel jack to the board and USB networking too. Jan 30 05:08:15 BBBW. Jan 30 05:10:41 It is weird. Jan 30 05:10:45 Let me explain. Jan 30 05:12:05 One L298 handles a criss-cross of actuators. So, the U3 (L298) handles the M2 and M3 GPIO pins. Jan 30 05:12:36 But...the board has the M1 and M2 closest to one another. That is all. Jan 30 05:13:15 That same U3 handles PWM1A and PWM2B too. Jan 30 05:17:47 GenTooMan: Have you noticed if anything has changed on the BBBW side of things? Jan 30 05:18:01 I assume the other actuator works? Does the L298 have an enable signal and is it enabled? Jan 30 05:18:49 The actuator works yes and LEDs show for motor1 and motor2. Jan 30 05:19:07 I thought it did. Jan 30 05:19:10 I can try again. Jan 30 05:19:32 I usually set up a server to test things for fun. Jan 30 05:19:55 I mean, if the dang server works, historically, my motors turn. Jan 30 05:19:59 I will keep checking. Jan 30 05:21:56 hmm can you manually test the motor drivers? Jan 30 05:22:11 I did...sort of. No. Jan 30 05:22:29 I tested the output terminals where the drivers lead to... Jan 30 05:23:01 It could be the source. Let me just make sure. Jan 30 05:28:46 Dang it! Jan 30 05:29:10 Now...Internal Server Error when the page/server online has me pushin' the radio button to turn things on. Jan 30 05:29:11 Blah. Jan 30 05:36:45 bleah or blah? Jan 30 05:36:47 Okay sir, please forgive me. I will leave you be for now. I messed up the server somehow. Not sure right now but I will be here. Jan 30 05:37:08 I will be here but in and out trying to fix this dang server! Jan 30 05:37:30 I think I know how. Patience young Fortune Master! Jan 30 05:37:36 perhaps you should go to sleep and do so with full cognition? Jan 30 05:41:17 Nope! Jan 30 05:41:21 Nighthawk Time! Jan 30 05:41:39 cognition/smognition. Jan 30 05:43:18 well night sleep seems something I need Jan 30 05:46:04 No. Jan 30 05:46:17 YOu just missed this enormous bug that hit me, came close though. Jan 30 05:46:31 TX Mosquitto! Jan 30 05:48:31 Big 'un! Jan 30 05:58:39 Yep. My fault. Jan 30 05:58:51 I had some bad source in my TX Mosquitto. Jan 30 05:58:58 Oh well. Olay! Jan 30 05:59:08 "He was a man of many faces." Jan 30 05:59:13 Geaux BBB! Jan 30 05:59:27 Now to put everything back. Jan 30 05:59:29 Yikes. Jan 30 06:02:19 Quadruped on the way, homey! Jan 30 06:02:33 Over a 2 instead of a 3. How silly. Jan 30 06:02:35 Aw! Jan 30 06:02:56 Blah. Jan 30 06:10:16 10:00! Time for sleep. Jan 30 06:10:54 * set_ keys banjo music! Jan 30 06:11:48 For when anyone wakes, is is possible to stack two MotorCapes on each other? Jan 30 18:09:05 Hello...is it possible to stack two MotorCapes on one BBBW and have access to the eight DC motors? Jan 30 18:39:26 which interfaces do they use? Jan 30 20:14:54 is there way to force a clock provider to enable an output without having an actual consumer requesting it? device-tree only solution Jan 30 20:15:40 for example to make a clock available on a pin header for a cape or something? Jan 30 20:23:48 mru: I use gpio and pwm. Jan 30 20:56:58 bbl... Jan 30 22:24:47 GenTooMan: Are you around? Jan 30 22:25:30 I am asking b/c i am trying to understand something about joints on machinery. I was thinking you may have a good resource for joint making for bots. Jan 30 22:26:00 I know it may not be your field but I figured this stuff was interesting to you. Jan 30 22:30:18 You and everyone else already did the heavy lifting by making the BBBW, the MotorCape, and the image (plus tons of other stuff). Jan 30 22:30:35 I figured some light banter would be nice? Jan 30 22:59:00 Okay. So, I have two dirs, four files, and more on the way for this bot. Wait! Jan 30 23:22:15 Okay. Forget mechanical. Jan 30 23:22:20 Not fun. Got it. Jan 30 23:23:41 I was looking up how to install five python files in a bash script...done. Now, I need to understand how to make that server available from those five files in a systemd setting, i.e. service or whatever. Jan 30 23:24:45 Does this sound like the BBBW can handle concurrentcy in this way? Jan 30 23:51:25 Yippee! Jan 31 00:22:37 Nope. Jan 31 00:51:26 You may wish to study threading. Jan 31 01:56:14 Thank you. Jan 31 02:13:23 threading! **** ENDING LOGGING AT Sun Jan 31 02:59:57 2021
