**** BEGIN LOGGING AT Sat Apr 23 02:59:56 2022 Apr 23 04:04:05 10:00! Apr 23 14:50:04 zmatt: If I am sending messages via a ring buffer from the PRU how much time do you think it takes to execute that Apr 23 14:50:39 I am looking at the time stamps of the messages and it is roughly 20ms gaps between each one Apr 23 15:03:23 not sure what you mean, it's sending one message per iteration of your loop, so the message rate will be exactly equal to the sample rate of the load cell Apr 23 15:05:07 and I'll see if I can do a little test later to see if I can figure out why you're having trouble with gpio, maybe there's a non-obvious mistake in my header or something Apr 23 15:18:27 ok Apr 23 15:18:38 so I turned off any filtering Apr 23 15:19:05 so that puts me at 1200 samples per second but I do not see a performance boost on the message stream Apr 23 15:19:42 I am wondering if i have a bottleneck somewhere... I just have a code that takes the message and dumps it to a file Apr 23 15:19:57 so this is like best case scenario Apr 24 02:16:10 I am not sure if you are here but I chatted w/ you about a metal bender about two years back. Anyway, it is for a part of bent metal for the electronic mower managed by the BBBW. Anyway, I got it working. Apr 24 02:16:34 So, I am one step forward and two steps back so far. Getting Closer? Apr 24 02:17:47 Now, if I can figure out PWM on the BBBW along w/ some drivers in C/C++, I can finally finalize the C/C++ program. Apr 24 02:18:39 Anyway, that is where I am at currently on this green machine. Apr 24 02:19:34 It would be cool to have a starter too but I think I am going green on the green machine. Apr 24 02:34:08 bent metal? Apr 24 02:34:43 that sounds like the name of a band. Apr 24 02:40:41 Yes. Apr 24 02:41:32 Bent metal for manufacturing the build of the mechanical aspects, i.e. tensioner, belt, and idler. Apr 24 02:41:45 Yep. Apr 24 02:42:05 The instructions on this metal bender is, well. Horrible. Apr 24 02:42:26 It is the pits. Now, i can move on and make this mower more functional. Apr 24 02:44:54 The only issue so far is the PWM on the BBBW, the tensioner clamp is too big (larger in diameter than 10mm), and I need to lengthen some wiring. Apr 24 02:46:16 I do a little bit of Fusion 360 3D modeling, and I know they have a "sheet metal" mode, but I don't know anything about it. I hope you find what you're looking for here. Apr 24 02:50:19 PWM! Apr 24 02:50:53 I am looking for chat only. I enjoy BBB based ideas, the education part to it all, and just building random things. Apr 24 02:51:40 i was trying to build around the repliCape recently but the mfg. of the Cape are no longer building the boards/Capes. Apr 24 02:52:38 Luckily, Seeed Studios produced a Cape a long time ago, the MotorCape is still around, and who knows? I may just build some more Earthly green machines. Apr 24 02:56:35 i was watching the replay of the Open Hardware Summit. Odd but intriguing. I liked the effort those people do to produce better filaments in Open Source/Hardware ideas. They were helping to produce pellet printing (not just filament) and also awkward sized chip/fragment printing. Apr 24 02:56:38 That is neat. Apr 24 02:57:24 I could just chip and chop a bunch of plastics and shove in down the extruder...Ha. Neat. Apr 24 02:58:04 And all their work is done in the light of day...Open Source and Open Hardware (for their type of extruder). **** ENDING LOGGING AT Sun Apr 24 02:59:56 2022
