我是在protues中仿真led左移的情况，用51单片机进行控制，成功的实现了8*8点阵的移动-I was left protues the simulation led to the situation, 51 MCU control, successful implementation of the 8* 8 matrix of mobile

基于BHL2000实现字符灰度显示，本项目主要由三个模块构成：51单片机控制模块、BHL2000灰度调制模块、LED点阵显示模块。用AT89S51单片机产生16*16LED点阵的行扫描信号，并且由单片机控制BHL2000灰度调制芯片，输出调制后的驱动电流控制LED，实现LED点阵256级灰度显示。(Based on BHL2000, the character gray display is realized. This project is mainly composed of three m
