以高性能数字信号处理芯片TMS320F2812为核心,设计生成了基于不对称规则采样算法的SPWM波形,键盘输入参数设定调制波频率。本文首先分析了不对称规则算法的原理,接着设计了基于TMS320F2812芯片的软件设计流程,最后在数字示波器上显示了实验波形-To high-performance TMS320F2812 digital signal processing chip as the core design is generated based on asymmetric rule sampling SPWM waveform, keyboard input parameter modulation wave frequency. This paper analyzes the principle of asymmetric rules algorithm, and then design the software based on TMS320F2812 chip design process, the last in the digital oscilloscope shows the experimental waveforms
