本程序的目的是产生SPWM波形，利用单片机技术，采用VC++语言，生产SPWM波形，经LC滤波后即可输出交流信号-The purpose of this program is to generate SPWM waveform, using chip technology, using VC++ language, production SPWM waveform, can be filtered by the LC output AC signal

单文档实现VC绘图，从单片机不断接收并处理十位二进制数据，用VC绘图方式将波形显示在电脑上-Dialog box realize VC drawing, receive and deal with the serial datas from the MCU, displays on the computer by drawing
