提出一种基于R61581显示驱动芯片实现液晶显示屏驱动的方法。本方法以STM32为主控制, 采用可变静态存储控制器(FSMC)接口实现R61581显示驱动。文中具体给出STM32与R61581的硬件连接方式以及FSMC的软件配置方法, 并给出基本字符图形显示验证方法。实验证明: 该FSMC接口硬件连接简单, 液晶显示操作占用系统CPU资源少, 800×480分辨率屏幕刷新率达到42FPS, 可支持大部分液晶屏的驱动。

Based on R61581 display driver chip, a LCD drive method is proposed. It uses variable Static Memory Controller (FSMC) interface of STM32 to drive the LCD screen by R61581. paper proposes method about STM32 connected with R61581 and FSMC software configuration, and puts forward the basic character graphic display authentication methods. Experiment results of the method about FSMC is simple, LCD display costs less system CPU resources, 800×480 resolution screen refresh rate is 36FPS, can support most of the LCD screen driver.
