That is pretty much just a raw H-Bridge driver. The PWM output from the PRU will not be nearly fast enough to provide smooth operation. I suggest you use one of the BBB's hardware PWM channels running at about 20 KHz (the PWM frequency recommended by Pololu). While the PWM pulses need to be generated quickly, updates to the PWM can happen slowly. I suggest you write a simple user-mode Python HAL component and use one of the available libraries to drive the hardware PWM logic. -- Charles Steinkuehler [email protected] -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
