Interfacing the MPC17C724 Stepper Motor Driver with an 8-bit HCS08 Microcontroller
Technical guide for interfacing the NXP MPC17C724 dual H-bridge motor driver with HCS08 microcontrollers to control bipolar stepper motors in portable electronic applications.
Overview
This application note (AN3302) describes the integration of the NXP MPC17C724 dual H-bridge motor driver with 8-bit HCS08 series microcontrollers, including the MC9S08QG8 and MC9S08QG4. The document provides a detailed hardware and software overview for controlling stepper motors, illustrated through a 3-axis plotter design. It covers the MPC17C724's 0.4 A continuous current capability, four driving modes (Forward, Reverse, Brake, and Tri-state), and internal protection circuits. Additionally, it outlines the software setup using CStep and the MCU's parallel port interface to translate instructions into motor control signals.
Use Cases
- Portable electronic applications
- Camera lenses and shutters
- 3-axis plotter mechanisms
