I’m using a BBB with LinuxCNC to retrofit an old CNC mill. I have all of the stepper motors working, but I would like to add programmatic control of the spindle. The motor drive uses an analog signal, so I bought a digital pot so the speed can be controlled digitally. How do I add support for this with the existing HAL code? I want to retain the extruder control so I can use the mill for a 3d printer. I have a link to the digital pot’s datasheet below. Thanks for the help.
