HRPWM

您好:

    我在使用ti提供的hrpwm_duty_sfo_v8.c的例程时,在ccs中编译能通过,就是下载不到板子上,我不知道什么原因,程序都对着。我还想问一下它可以实现调占空比精度为150ps吗?

  • 你好,请问一下具体是哪款芯片?例程的路径是哪里?
  • 您好, 

        我的板子是F28377,我其实想用hrpwm实现调相150ps的精度,可以实现吗?在示波器上可以看出那么高的精度要求吗?谢谢您!

  • 可以实现,参考计数手册15.14.1.7 Scale Factor Optimizing Software (SFO):
    The micro edge positioner (MEP) logic is capable of placing an edge in one of 255 discrete time steps. As
    previously mentioned, the size of these steps is on the order of 150 ps (see device-specific data sheet for
    typical MEP step size on your device).
