摘　　要：在基于32位微处理器MC68331的剑杆织机监控系统中,设计实现了其液晶显示系统。完成了液晶显示控制板QPY ENH6255、液晶模块LM64P83L和MC68331之间的接口设计,并提出了控制板和微处理器接口的一种新的时序转换方法。最后介绍了本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 new timing conversion method of interface between QPY - ENH6255 and MC68331, which solved the redundant logic circuit for the timing conversion between Intel8080 and M6800.
