5i25, 6i25, 7i92, firmware request. was created by tommylight
PCW, i am really sorry to bother you, and this is absolutely not critical in any way shape or form, it is just for testing and experimenting, and maybe, just maybe to be used in a 4 axis wire EDM in the near future, like next month, if we survive this cr@p with viruses.
Request:
PWM with dir on pins 2 to 9 and encoders on pins 10 to 17, pin 1 as IO as it would be used for enable. On both headers. For the cards listed in the title.
Thank you very much for your continued support.
Regards,
Tom.
EDIT:
Attached two versions of firmware:
>lotsofenc.zip is for Mesa 7i92 with the "normal" 7i92_5abob pinout but each of the encoder inputs are A only, meaning it can count 6 encoders, used for plasma cutters with THCAD leaving two pins free on each header.
>7i98_sv8d.zip Is for Mesa 7i98, see below
>sv8d.zip is for Mesa 5i25/6i25 and 7i92, having 4 PWM/DIR and 4 encoder A/B inputs on each header, pin 1 used for enable. Example for this is below with configs included.

After some testing today (with Mesa 6i25) and yesterday (with parallel port), i can confirm that those litle cheap BTS7960 drives are quite usable and plenty powerful.
There is however a minor issue of me ordering the wrong firmware for them, they require UP/DOWN PWM, not the PWM/DIR type, i did change that in hal and they do work very nicely in one direction while in the oposite direction the motor is noisy and vibrates a lot while turning, and that is confirmed by the ferror plot on the scope. Since i did not get all my stuff back in the shop i i had no way of checking if the signals on both outputs are the same, so here is a question, might that be due to the dir pin not being same as the pwm pin in reaction time, i.e. in firmware is there a difference ?
Sorry to bother, my bad.
I will do some more testing in the mean time.
Thank you.
Forgot the video link where it can be heard while the motor is turning.

Got the scope out, dir pin is still a dir pin, so that will not do, unfortunately, for this type of drives.
I have others that use pwm and dir, so no big deal.
Again thank you very much for your support.

Hmm.. up/down PWM is just a mode:
setp hm2_xxxx.0.pwmgen.00.output-type 2
is it possible you have a:
setp hm2_xxxx.0.pwmgen.00.output-type 1
somewhere else in the hal file?
setp hm2_xxxx.0.pwmgen.00.output-type 2
is it possible you have a:
setp hm2_xxxx.0.pwmgen.00.output-type 1
somewhere else in the hal file?

Hold on just a sec, i have that set in hal as mode 2, but found some other error in the hal file, namely the same pwmgen being set to mode 2 and then to mode 1 lower in the hal.
I found it making sure i did set it.....
Sorry for all the trouble, back in a jiffy with more results and a new video.

PCW, thank you.
That was it, it was set to 2 and then 1 later on in hal.
Sorry for the mess.
It work perfectly.

On request from youtube user, attached is the config for this setup, both for parallel and Mesa 5i25/6i25. For Mesa 7i92 use the text editor and use the "search and replace" function to substitute the card name.

For some reason forgot to add the video of it working properly.
