AN2197: Stepper Motor Driver Application Circuit for Smart Gauges

AN2197 Application Circuit shows how to use the PSoC (Programmable System-on-Chip) to drive a low-power stepper motor for smart pointer gauges. This application demonstrates how to perform micro stepping in the stepper motor using PSoC 1. In addition, this application demonstrates using a PC-based utility to control the pointer position in the stepper motor
