**** BEGIN LOGGING AT Tue Aug 23 02:59:56 2022 Aug 23 11:41:14 Good morning... Aug 23 11:42:21 Early bird gets the MOSFETs. Aug 23 11:43:51 If the power goes out, it is b/c of this darn early morning storm. Aug 23 11:44:57 Anyway, GenTooMan: I finally think the video is up and ready. It is no cannon at mach one but it works... Aug 23 11:46:02 This is my good mower. So, no. It is not a bot yet. Aug 23 11:48:57 about 32 minutes of mow and music! : https://youtu.be/74nnIaNUFHk Aug 23 11:49:37 I even have the background noise from the mower making loudness reality. Aug 23 11:51:56 Dang it. It is private. Blah. Too many options. Aug 23 11:52:39 Has anyone used the Brookwood Designs from Tindie to allow the BBB to manage a CNC? Aug 23 11:58:45 GenTooMan: Okay, I think (think) this is it: https://youtu.be/74nnIaNUFHk is the link to try now. Nothing special except mowing. Aug 23 12:04:06 * set_ goes back to randomville. Aug 23 16:07:06 zmatt: gift from ti.. ;) https://www.ti.com/lit/ug/spruj61/spruj61.pdf Aug 23 16:23:13 ooooh Aug 23 17:30:16 rcn-ee: nice! now all they have to do is eventually reintegrate it into the TRM and they'll have repeated all the steps they did with the AM335x PRUSS documentation ;-) Aug 23 17:44:22 rcn-ee: any chance you could get me ssh access to an ai64 so I can work on improving py-uio support? Aug 23 17:49:48 jkridner: btw, mouser is still showing the ai-64 as shipping-restricted ("Mouser does not sell this product in your region.") here in the Netherlands Aug 23 17:52:22 The part is obsolete says the datasheet in th ebegining, lke a retired part is it ? Aug 23 17:53:12 @zmatt same in the UK but I got it overnight from RS instead Aug 23 17:53:42 jfsimon1981: nah they just mean "we don't want to have to provide support to developers" Aug 23 17:55:06 mayab: good call, they're not linked from the ai-64 page... maybe that's why they still have stock ;) Aug 23 17:55:40 could be. price was higher than I remembered it being when I first saw it on Farnell Aug 23 17:56:13 but no UK farnell, so couldn't get it from them either Aug 23 17:58:02 yeah, farnell lists €163.80 versus rs €190.35 (both ex VAT) Aug 23 19:25:54 Ok maybe yes Aug 23 19:36:34 zmatt: i'm working on getting more boards too, i'll see what i can do.. **** BEGIN LOGGING AT Wed Aug 24 01:00:24 2022 Aug 24 01:28:03 What does, "16 Software Events generated by 2 PRUs," mean in the ideas around 'Software Events?' Aug 24 01:29:00 I saw what rcn-ee posted earlier about the BBAI-64 quarduped of PRUs and I looked. Aug 24 01:29:03 I am still looking. Aug 24 01:29:36 Um, software events means GPIO rising, falling, or both? Aug 24 01:32:04 Sorry. I just ought to not be funny but it is really difficult for me to NOT pretend to be funny for some reason. So, quarduped is quadruped b/c of the number of available PRUs on the BBAI-64. Aug 24 01:33:02 I just learned about delta-sigma and "Software Events" is giving me chills. What does it mean? Aug 24 01:39:02 And then...they just say EnDAT w/out explanation. Aug 24 01:41:43 @zmatt: You say I make no sense. Have you read what rcn-ee posted earlier today, i.e. not the entire 1076 pages but on page 9 at Figure 3.1 there is a sentence. Fog Hat? Aug 24 01:42:22 ... Aug 24 01:42:37 Anyway...make sense out of this one. Aug 24 01:42:57 Figure 3-1. The PRU_ICSSG wrapper multiplexing is described with the device-level signals in . <<< Aug 24 01:45:24 Hence the space and then the period. It is typed up exactly that way. Aug 24 02:00:22 The space fooled me. Aug 24 02:00:43 So, in that figure, the signals are in the middle of the diagram? Aug 24 02:03:10 Silly, I know but I am me. So, I am sure everyone knows. Aug 24 02:04:38 The registers in question for GPI/O (or others depending on things) for the PRU(n) make one want to look in CTRL_MMR0! Aug 24 02:04:56 Phew and I thought space was difficult. Aug 24 02:06:23 You got PWMs out the wazzoo! Aug 24 02:07:21 Eight! Aug 24 02:08:15 The IEP are out on certain ones. Aug 24 02:08:37 Sorry. Chattin' to myself here. Aug 24 02:15:14 That was just 0. Aug 24 02:15:34 You got a new set of the PWMs w/ 1 and then the UART one. Aug 24 02:15:45 You got an entire car here. Aug 24 02:19:51 And...then there is the IEP but some are disqualified for use w/ specifics. These specifics are, and I quote, IEP1 is not muxed. Aug 24 02:20:13 It could have been a data trolley! Aug 24 02:29:28 GenTooMan: I am learning again! HiZ. High Impedance! Aug 24 02:30:19 Dang it. Everyone leaves. Aug 24 02:37:03 What does NEG mean when in relation to PWM under the PRU SS? Aug 24 02:37:41 I think POS means Position or Positive. Oh. It probably means negative. Aug 24 02:37:43 Okay. Aug 24 02:39:44 Yep. Aug 24 02:42:49 GenTooMan: Did you see my video of the mower doing things? Aug 24 02:43:08 Side discharge! Aug 24 02:45:29 Marvel engines doing things! Not a bot. There was a human behind the handle bars. I know...boring. Aug 24 02:45:47 Ut oh! Aug 24 02:45:59 * set_ goes hide in the waters. Aug 24 02:57:29 Okay, back from waterland. What speed can the EDIO from the PRU function? Aug 24 02:58:20 So, it seems that the CTRL_MMR0 is slow and I was mistaken on its use. I should have skipped. Aug 24 02:58:40 I could have skipped to the register section to learn more. **** ENDING LOGGING AT Wed Aug 24 02:59:57 2022
