I wonder about the following:
For some time, I have my stepper motor controller (A4988) connected to the Raspberry Pi‘s GPIOs and leverage on the great astroberry-diy library (astroberry focuser).
Alternatively, one could use an Arduino, connected via usb, to connect to the driver, e.g. Pololu A4988. See for instance:
hansastro.github.io/Focuser/
But why putting an Arduino in-between? I have seen, that on the Pololu website there is also a stepper controller that can be connected directly to USB, see www.pololu.com/docs/0J71/all
So, in theory (unfortunately I am lacking of the programming skill), wouldn’t it be possible to address the stepper controller via usb?
www.pololu.com/docs/0J71/12.1
Just thinking it would need a driver like the Astroberry drivers that enables to connect the the stepper driver via usb.
Why of interest - it would allow using mini pc‘s with usb 3.0 instead of the Raspberry Pi - and without the need of an Arduino.
Any views?
