采用STC-51的STC12C5202AD芯片产生50HZ正弦波的SPWM调制发生器,50HZ generate sine wave of SPWM modulation generator

在MCS51上分别利用C和汇编编写了led红绿点阵、利用PWM通道产生方波和正弦波、利用RS232串口通讯和触摸屏配置组件。经验证，能成功运行-In which use the MCS51 C assembly compiled a red green dot matrix, use led PWM channels have sine wave, use of square wave and RS232 serial communication and touch screen configu
