摘要
通过分析和研究嵌入式微处理器LPC2378和液晶模块OCM12864-1的功能特点,利用自主设计LPC2378系统板和OCM12864-1液晶模块构建了一个菜单显示系统。从软硬件两方面阐述了LPC2378与液晶模块之间的接口电路和程序的设计方法,解决了高速ARM处理器与慢速液晶模块之间时序匹配问题并给出了液晶模块的初始化程序。系统实际运行情况良好,验证了本设计的可行性。
By studying and analyzing the functional properties of Embedded Microprocessor Unit of LPC2378 and OCM12864-1 LCD module,a LCD menu display system based on LPC2378 system board has been constructed.Both the interface circuit and program design methods between the LPC2378 and the LCD module are discussed.The timing compatibility problem between high speed ARM processor and slow speed LCD model is solved and the initialization procedures are provided.This design has been proved feasible according to the actual operation.
