Controlling the motors is done through [Guy Carpenter]’s Switec X25 library for the Arduino, allowing an Arduino Uno to control up to three stepper motor gauges simultaneously.

Microchip’s stepper motor control library enables the development of high-speed stepper motor control applications with variable micro-stepping down to 1/64 of a step.

Leveraging the Trinamic TMC2208 stepper motor driver gives Ethersweep silky smooth and quiet motor control, which could be very important for some applications.

AMI Semiconductor, a manufacturer of integrated mixed-signal and structured digital products, has introduced two single-chip stepper motor controller ICs.
