摘要
文章介绍了用串行方式来实现微处理器控制液晶显示驱动器的方案。该方案通过程序设计利用MCU的I/O端口去模拟串行总线,从而实现了控制LCD的目的,并介绍了液晶显示模块LCM128645ZK的性能特点,以AT89C2051为例给出了2线串行接口的硬件电路和控制程序。
A Scheme of MCU controlling LCD block by serial mode is introduced. The port of the MCU is used to simulate a serial bus through programming, so as to implement controlling the LCD.The characteristics and work mechanism of LCM128645ZK are explained together. Beside the circuit of 2-lining serial interface between AT89C2051 and LCM , the controlling program is presented.
