利用avr atmega128芯片编写的spwm程序，通过PB0、PB1两个IO口数出相位相差180度的SPWM波形。-spwm program for avr atmega128 microprocessor,the wave output from PB0 and PB1 I/o.

avr单片机产生的spwm波形程序，测试过，可以实现功能，不过波形有失真-waveform generated spwm avr microcontroller program, tested, can function, but there is distortion of the waveform

SPWM程序，用AVR编写的，程序简单易懂，很实用，我是初学者。-SPWM procedures, the use of AVR preparation, and program simple and understandable, is very practical, I am a beginner
