单片机ＩＯ口不足，用此电路做的键盘电路和程序，就可以了 8条口线24按键的C51源程序 .rar-SCM IO insufficient use of this circuit keyboard circuit and procedures on the eight lines mouth of the 24 keys C51 source. rar

* 功能：使用PWM6输出PWM信号，通过滤波电实现DAC转换。由KEY1控制PWM的占空比， * 每按一次按键将会改变一次PWM的占空比。 * 说明：使用示波器观察测试点PWM和PWMDAC。-* Function: Use PWM6 output PWM signal, by filtering electrical realize DAC conversion. Key1 controlled by the PWM duty cycle,* every time a button will change the PWM duty cycle.* Note: Use the oscilloscope to observe test points PWM and PWMDAC.
