摘　　要：在基于32位微处理器MC68331的剑杆织机监控系统中,完成了控制板QPY ENH6255,液晶模块LM64P83L和微处理器MC68331之间的接口设计,介绍了控制板和微处理器接口间一种时序转换方法的软硬件实现。介绍了系统初始化程序的设计方法及汉字菜单显示程序的设计流程。For Real- time operation to the working loom, the display system is essential. By applying with LM64P83L, QPY- ENH6255 and MC68331,the paper realized a design method of the hardware and software of LCD display system, which is a subsystem of the rapier loom supervisory system. In the design,we validated a timing conversion method of interface between QPY - ENH6255 and MC68331, which solved the redundant logic circuit for the timing conversion between Intel8080 and M6800.
