求助：按键控制led小灯的亮度变化由于板子没有PWM模块，自己写了一个程序。要求是用8个独立按键（从矩阵分离而来）控制8个led小灯的从灭到亮的过程，按一个键显示一个灯的状态。现在的问题是按第一个键没问题，按下一个键的时候上一个灯的状态不会消失，结果就是按完8个键8个灯都亮了，请问怎么回事啊？求解！

求助：按键控制8个led灯的亮度变化过程想要的结果是按一个键显示1个灯，但是现在的结果显示是按了下一个键后上一次灯的状态不会消失，按了8个键8个灯都亮了。请问大家怎么回事啊？ #include <reg52.h> sbit D1=P1^0; sbit D2=P1^1; sbit D3=P1^2; sbit D4=P1^3; sbit D5=P1^4; sbit D6=P1^5; sbit D7=P1^6;
