关于HRPWM输出高精度占空比使用问题

Other Parts Discussed in Thread: C2000WARE

DSP型号是28377D。

求助:怎么判断高精度功能是否生效?

通过CPMA和和CMPAHR位来控制PWM波的下降沿,由于CMPAHR影响很小,该如何确定CMPAHR有没有生效的呢?给支个招吧?

  • 这个要观测我觉得很难啊,你可以用官方提供的HRPWM例程:C:\ti\c2000\C2000Ware_3_01_00_00\device_support\f2837xd\examples\cpu1\hrpwm_prdupdown_sfo_v8
    修改里面的变量UpdateFine的值观测启用和未启用HRPWM的波形
