7i95T convert all step/dir to PWM?

7i95T convert all step/dir to PWM? was created by heathmanc
I’ve got an issue. I have a 7i95T board and Pico Systems brushless DC drivers that take PWM input. I assume I need a new firmware to convert all step/dir to PWM? Can anyone help me? Additionally, I assume this won’t interfere with the 2 serial ports?

7I95T firmware with all step/dir replaced with PWM/Dir

Thanks! Greatly appreciated! I assume I can use a SPINx1 on one of those PWM/dir channels?

Sorry to bother you some more. I happen to have a ton of cards I bought years ago lying around. Do you think a better solution might be a 7i80hd-25, use a 7i52s configured for 6x PWM output and 6 encoder inputs (only using 3 of each for now). I have a 7i44 and multiple input/output card options.

It would be about the same, but you would likely need to add
some additional I/O cards for general purpose inputs and outputs.
(that are built in on the the 7I95T)

Thanks for the feedback. Any tips on creating a pin file for the 7i95t firmware you sent to use in mesaCT?

I'm not sure how MesaCT determines card resources.
Is this PWM setup for interfacing with PWM motor drives
and using encoder feedback?
If so, a 7I97T configuration would be close
(with perhaps some PWM frequency/mode changes)
