基于STM32的RA8806控制器LCD设计

摘要

RA8806点矩阵液晶显示控制器内置字库、触摸屏和键盘接口,具有功能强、移植性强、性价比高的特点,比其他同类产品更受设计人员欢迎.采用RA8806控制器的LCD可以充分满足STM32嵌入式系统的各种液晶显示需求,为了实现这一目的,给出了在STM32上驱动该控制器的方法、触摸屏校准的思路及部分程序,并在实验中得以实现.%RA8806 LCD controller with built-in dot matrix font, touch screen and keyboard interface has features of strong function, easy transplantation, high performance-to-price rate. RA8806 LCD controller can be used to fully meet the requirement on liquid crystal display of STM32 embedded system. The drive method of the controller based on STM32, the calibration ideas of touch screen and part program are given in the paper, and realized in experiment.
