摘要
介绍了基于飞思卡尔S12系列单片机的微型热敏打印机的组成,详细分析了其工作原理,给出了热敏头过热保护以及步进电机驱动模块的设计与实现方式。热敏打印头采用同步串行外设接口实现数据加载。
The constitution of micro-thermal printer based on Freescale S12 family of single-chip microcomputer is introduced. The operation principle of micro-thermal printer is described in detail. For the thermal head, the design of the protection and step motor drive module are implemented. The data are loaded through serial peripheral interface.
