摘要
介绍了基于DSP-TMS320F2812控制的点阵式液晶显示模块LCD-HS12232的实现方法及其应用接口,给出了硬件接口和软件设计方案。采用模块化的程序设计,实现了LCD-HS12232在设备状态监测系统上的应用,并针对实际设计过程中出现的多任务操作效率问题给出了解决方案。模块化设计的系统有方便的用户接口,可以在多种DSP控制系统或数据处理系统上移植。
Design of LCD-HS12232 dot-matrix LCM based on DSP-TMS320F2812 and it＇s application interface are introduced. The design method of hardware interface and software program are provided. Modular program design of showing section is proposed, and its application in device monitoring sys- tem is discussed. Specific issues of multi-task operating efficiency in the design process are solved. Structured design system has convenient user interfaces and can be transplanted to many DSP control and data handling system.
