Greetings all; There has been a discussion of the BeagleBone's 'PRU' (I think I got the acronym right) in terms of using it as a stepper driver. That does sound promising, but no one has said so far, how many of these PRU's can be programmed on one BeagleBone. As it appears to have more than enough GPIB pins to get the job done, the question I have is: How many of these PRU's can it actually maintain and service?
$125 for the devel kit is a price I'm not doing if its $125 per stepper being controlled. But if it can do a PRU per GPIB pin, its going to be a lot more appetizing. And even moreso when a breakout board has been built for a reasonable price that actually gives us the ability to use all of the GPIB pins, which will approximately double the number of pins available from a parport setup.
