MCU:89C51,89S51,89C2051等
晶振:12MHz
电路驱动(LED连接):
P1.0连接蓝色LED
P1.1连接红色LED
P1.2连接绿色LED (必须使用纯绿色高亮LED,不可使用普通草绿管)
全为低电平驱动(低电平点亮),可以加三极管驱动,红、蓝、绿LED也可以交换位置
控制方式:PWM
频率:约300-700Hz(我没有计算或测量过,只是试验显示效果足够好)
调节级数:共600级,相当平滑

入无法下载HEX,大家可以用KEIL自己编译,或者使用记事本保存HEX代码(重命名为.HEX文件)都可以
再把.hex文件写入单片机,接好电路即可工作
自己做的LED渐变灯(使用三极管8550驱动)及部分效果图:
