S3C2440A下彩色液晶显示系统的设计,以三星公司的嵌入式微处理器S3C2440A和夏普公司3.5inLCD屏LQ035Q7DH01为基础,设计了显示硬件电路,介绍了帧缓冲设备的处理机制及底层驱动的接口函数,针对本显示系统给出了如何开发其Linux帧缓冲设备驱动程序。不论是显示硬件电路还是软件驱动程序,都有很强的可移植性,可以方便地移植到不同的平台。-S3C2440A under the color LCD display system designed to Samsung' s S3C2440A Embedded Microprocessor and Sharp 3.5inLCD screen LQ035Q7DH01 based on the design of display hardware circuit, introduced a frame buffer device handling mechanism and the low-level driver interface functions for The display system shows how to develop the Linux frame buffer device driver. Both the display hardware circuitry or software drivers, there is a strong portability, can be easily ported to different platforms.
