摘要
液晶显示屏在工业领域应用广泛,工业控制系统的工作环境比较复杂,一般情况下都存在自然因素或者人为因素产生的电磁干扰。对目前常用液晶控制器设计的方案进行对比分析,提出基于STM32的液晶控制器设计,采用单片机+显示控制芯片的设计方法。单片机采用STM32F407作为主控芯片,配以SSD1963显示控制芯片,并配置128M*8bit的片外Flash用于图片储存。软件系统设计移植嵌入式操作系统μC/OS-II,进行多任务处理,成功设计一款液晶控制器。
Liquid crystal display is widely used in the industrial field since the working environment, the industrial control system is complex with electromagnetic interference generated by natural or human factors in general. Based on comparative analysis of the current commonly used liquid crystal controller design scheme, puts forward the design of LCD controller based on STM32, uses SCM + display control chip design method. MCU STM32F407 is used as main control chip, with SSDl963 display control chip, and the configuration of the 128M*Sbit chip Flash is used for image storage. The design of software system transplants the embedded operating system ~C/OS-II for multitasking to make a LCD controller successfully design.
