摘要
为阐明用单片机控制单色显示屏的方法,对LED显示模块单元如何进行行列信号控制及信号传输中的驱动问题进行了研究。讨论了单片机控制系统中关键的数据发送问题,结果表明采用并行数据输入、串行数据及同步时钟榆出的专用电路可大大减少CPU的辅助时间,提高数据的发送速度。
It researches the matrix signals control of LED screen, information transmission and driving. In order to control black and white screen with SCM, it describes the data sending in SCM system. This system uses the parallel data input and series data output in- phase. The results show this can reduce the assistant process of CPU and increase the send speed.
