PWM problem in delfino 28335

Other Parts Discussed in Thread: CONTROLSUITE

Hello all

i want to ask about few things regarding epwm channels of delfino..

 

1. How much low frequenc can we achieved by using epwm modules as TBCRD is a 16 bit counter but when i load 65530 in it, i dont get any response on pwm lines...

similarly when i load values greater then 10000 i dont get any response... what is the problem in it??

 

regards

salman

    Salman,

    If the SYSCLK frequency of your F28335 device is 150MHz, the slowest possible clock frequency is:

    150MHz / 65535 / 2 = 1.144kHz (the divide-by-2 factor exist if you have configured your PWM to be in up-down count mode)

    Without more information I am unsure what your exact problem is.  I would recommend continuing to experiment and, if you haven't already, take a look at some of the PWM examples in controlSUITE.


    Thank you,
    Brett
