Hi there. I've been looking at motorised focusers and have decided that I'll probably just drive a stepper motor from the GPIOs of my Raspberry Pi [equivalent] using one of these:
My question is: how would I go about interfacing this into Indi? Would I write my own driver to meet a know focuser API, or is there a generic way of driving GPIOs I could adopt or what would you recommend?
Similar story! There is possibility to drive through GPIO in linguider (you just have to indicate the pins and export them) - would be very cool to see something similar in INDI
