AN2197 - Stepper Motor Driver for Smart Gauges

Last Updated: 
May 04, 2017

AN2197 shows how to use the PSoC® (Programmable System-on-Chip) to drive a low-power stepper motor for smart pointer gauges. This application note 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.


The world is digital today, and most of the information is represented in numbers. However, human nature is more ’analog’ and better represented in the old-fashioned way, using pointer gauges and bar graphs.

Pointer gauges are present in many industrial applications. Automobiles, trains, and even modern aircraft dashboards emulate analog gauge functionality on control flat-panel plasma or TFT screens.
