H-bridge motor driver support #105

Open ghost opened 9 years ago

ghost commented 9 years ago

I would like to use this firmware for my custom 3D printer, however I was looking at using H-bridge motor drivers instead of the traditional direction/step motor drivers to drive bipolar stepper motors. Would this be a feature you are willing to implement and support?

jgrjgr commented 9 years ago

you would only be dealing with full or half steps, and you would need to be running a chip with enough pins for it,

i do believe the desired effect is possible using a 4bit counter eg somthing like the 74ls93 chip or one of the many many similar ones,

It's a feature we'd be willing to accept a patch for. Actually, there is already some support, long time ago somebody brought in "Greycode". Not sure about its status.
