摘要
描述了目前嵌入式系统中人机界面的现实与要求,以Samsung公司的32位嵌入式微处理器S3C2440为例,详细说明了液晶显示控制器的功能及软件配置方法。结合Sharp公司640×480点阵的薄膜晶体管液晶(TFT型)与处理器的接口设计,给出了可方便移植的程序代码、具体的配置参数以及相关函数。实验结果表明了该接口软件设计的正确性和实用性。
The reality and requirements of human-machine interfaces isdescribed in the current embedded system.Taken the Samsung’s 32-bit embedded microprocessor S3C2440 as example,the function of liquid crystal display controller and software configuration is illustrated.It is also combined with Sharp Corporation of 640× 480 dot-matrix thin-film transistor（TFT-type） liquid crystal screen.On S3C2440 processor LCD controller interface,a convenient transplant program code and the specific parameters of the configuration is given.The experimental results show that practicality and correctness of the design of interface software.
