unipolar stepper driver - zero #11

Open VojislavM opened 7 years ago

VojislavM commented 7 years ago

Because the zero has the Linux OS, it is not suited for real-time GPIO operations like driving unipolar stepper motors. One solution is driver based on the i2c to PWM chip which drives MOSFET H-bridge drivers. There is a HAT for pi that supports this way of driving steppers, and it has a python library. https://www.adafruit.com/product/2348 This supports 5 wire unipolar steppers!
