The PRU's I think are meant to be flexible communication chips.
Instead of installing a chip for every communication protocol,
RS232, Ethernet, USB, I2C, CAN, Firewire, etc, etc, etc.
They put in these programmable chips, which you can basically program to act like a controller for any communication protocol.
Stepper drivers aren't communicated with via a protocol. It's just 3-boolean signals, Enable/Step/Direction.
So these PRU's aren't going to help in that aspect. You won't be able to just hand off the stepper instructions.
