Raspberry Pi to run both software + steppers

Hi,

Has any thought been put to using a Raspberry Pi for the controlling hardware, with a dual stepper driver running from its GPIO pins? Could bypass the need for any arduino at all if all its there for is to drive the steppers.

With a custom PCB, you can include the 5v/12v regulation and power through the GPIO pins.

Not sure on the processing power needed, but the new A+ layout/design is only £20.

hmm I think it would be better for timing to do this on a blackberry as you can put the time critical code in the DMA …

Hey @PA7T do you mean a Beaglebone Black maybe?
