用CH451芯片驱动LED点阵屏的电路设计
The Circuit Design of LED Lattice Screen Driven by CH451
摘要
CH451芯片可以动态驱动64位LED点阵或者8位数码管，具有速度快、功耗小、操作简单等特点，并可以很方便地通过1线或者可以级联的4线串行接口与单片机等交换数据。文章介绍了这种芯片的特点和使用方法, 并给出软硬件的设计实例。
Abstract
64-bit LED lattice or 8-bit digital tube can be driven dynamically by CH451. The chip can easily be adopted by 1 line or cascade of 4-wire serial interface to exchange data with the SCM. It has the characteristic of fast speed, small power consumption and simple operation. The characteristic and the using method of CH451 were introduced, and the examples of hardware and software design were given.
