C51单片机LED点阵显示数字

说明 通过P0 P1 P2 作为点阵接口　　　　　　　　　　

要求学员掌握 LED点阵的工作原理和 各点阵脚的定义及接法，具体接线请参考接线说明　　　　 *

*我们采用的LED点阵式是低功耗，在做实验时可以用单片机脚直接驱动　　-C51 microcontroller LED dot matrix display digital

Descr iption as a dot-matrix interface via the P0 P1 P2

Require students to master the definitions and connection of the working principle of the LED dot matrix and point position of the specific wiring refer to wiring instructions

LED dot matrix we used is a low power MCU pin can directly drive when doing the experiment
