TMS570LS1224: HET Timer issue

Part Number: TMS570LS1224

Hello,

I am receiving PWM signal on one of the HET Pin. I need to generate similar PWM signal from some other HET Pin parallaly.

Is there any such feature available in HET to implement this?

Best Regards,

Padmrish.

    Padmrish,

    HET allows you to configure any of the timer channels for input or output timer functions. The HET program can be written to perform these operations. What specific functions are you trying to implement?

    Hi Sunil, I want to output PWM signal similar to an input PWM signal. I am receiving input PWM signal on HET 4th Pin and i have to output same PWM signal on HET 2nd Pin. If duty and period of input PWM signal changes , i should change output signal too . Can you please suggest me any way to implement this. I am really stuck now and don't know much about HET instructions.

    Best Regards,
    Padmrish

    Hi Padmrish,

    The easiest way would be to generate an interrupt to the host CPU whenever a signal is captured, which can then update the required PWM period / duty cycle instructions. However, this method includes latencies related to interrupts and also updates to the HET memory.

    There could be a possible way to do this with just HET programming, but I don't have an algorithm that you can easily use for this.
