现有基于MAX7219芯片的数码管驱动电路只适用于小尺寸LED,为扩展其使用范围,在介绍动态显示芯片MAX7219功能的基础上,提出了一个基于该芯片的8位高亮度8英寸数码管驱动电路。电路保留了MAX7219芯片的功能强大、编程简单等优点,通过74LS273锁存器和ULN2803达林顿驱动器,实现了对任意大尺寸数码管提供较高电压和电流驱动的静态显示,并亮度可调。 Abstract: The existing display-driving circuit based on MAX7219 was only applicable to small-size LED. To expand its use, based on the function introduction of dynamic display chip MAX7219, a display-driving circuit for high-brightness 8-bit LED with the size of 8-inch was proposed. The advantages of MAX7219 were retained, such as powerful function and simple programming. Static display with adjustable brightness for large-size LED with higher voltage and current was achieved with the help of 74LS273 and ULN2803.
