10:14 <Duality> @zmat yea 9-bits both read and write but I think it'll be to difficult to achieve, we don't have pru's atleast we use a variant without them.

10:29 <Duality> i think you are correct if I want to properly implement the protocol then i'd have to write a driver that plays with the parity while sending out bytes

10:34 <Duality> either low level or with direct access from user space? but it needs to be semi real-time

12:36 <set_> I am messing w/ a PWM lib. from @zmatt...

12:36 <set_> Does anyone know about connections that should be made for the TB6600?

12:37 <set_> I have the datasheet and they are not correct...of course I am using 3.3v instead of sys_5v.

12:37 <set_> Maybe pathlib holds no use in Python3 on kernel 5.10.x?

13:15 <set_> I had it working and broke something. Blah.

13:51 <set_> Does this funny schematic make any sense: https://wiki.dfrobot.com/TB6600_Stepper_Motor_Driver_SKU__DRI0043 ?

13:51 <set_> It is an Arduino but I am using a BBB.

13:51 <set_> It is making me ______ and I have trouble being _______.

13:52 <set_> It has two PWM connections, a "GPIO" (I guess), and no GND?

14:10 <set_> Okay! New set up!

14:10 <set_> Their ideas are not what I can grasp. off to try set_ ideas now!

14:24 <set_> maybe the dip switch...

14:24 <set_> hmm

14:30 <set_> It would help if I knew something! Off to try GPIO60 as P9.12 and not P9.10. Oops.

14:32 <set_> Hmm. That is not it either. The code runs and my source does run too but no movement...

14:34 <set_> @zmatt: This is the source I am trying right now: https://pastebin.com/R70P1wAn

14:34 <set_> Is it b/c of GPIOD and no use for pathlib w/ gpio?

14:37 <set_> Also...where is the Compatibility Layer for handling /dev/bone/?

20:10 <set_> Maybe using a separate chip is a better idea, i.e. like a L298 for stepper functions...

20:10 <zmatt> Duality: if you're doing half-duplex rx+tx then you'll have real-time requirements for switching direction, if you're using full-duplex rx+tx you'll need to use separate uarts per direction since you can't (safely) be receiving while changing the parity for transmit

20:10 <set_> Working w/ GPIO and PWM is creating an issue...might just be.

20:21 <set_> I mean...I do not even know what is in this box so far. Too bad there are not ideas circulating. Oh well.

20:21 <set_> Back to the ole, drawing board.

20:24 <set_> @zmatt: Can I post your older model source on the forums to see if someone can help me w/ the build of this TB6600?

21:30 <set_> The motor is excited. I repeat, the motor is excited.

21:36 <set_> Luckily, it was moving slow. It almost broke itself!

21:41 <set_> Man. That was exciting! Thank you, @zmatt.

21:41 <set_> For some reason, this driver expects no ground or something...

21:42 <set_> Just a bunch of wires being fed into themselves via headers... 1. for GND and I guess it is like a switch and not a driver.

21:42 <set_> 2. This is the first time I have used a driver w/out GND.

21:43 <set_> I feel good.

21:50 <set_> opto!

21:55 <set_> GenTooMan: I am making makin' moves again!

21:56 <set_> You missed it as I cried for mercy...

21:56 <set_> Gooey OOey!

21:58 <set_> I can only be so smart or it is back to the ole farm w/ me...

21:58 <set_> Thank you!
