Hi all,
I've seen that many used PRUSS in order to generate the PWM signal needed
to drive DC motors...
Given that on the sitara already has there are the controllers that do it
in HW, I was wondering if it is feasible to program the PWMSS subsystem of
the Sitara, driving it from within the
talk to the PWM
hardware with the PRU.
