TM4C129ENCPDT: PWM clock configuration

Kurian Thomas P

Part Number: TM4C129ENCPDT
Other Parts Discussed in Thread: EK-TM4C129EXL

Hi,

I am using the launch pad EK-TM4C129EXL and IDE : Code Composer Studio (Version: 7.2.0.00013)

Recently start working with PWM firmware, have configured the system clock successfully to 120MHz and now am trying to configure the same clock to PWM; then found certain issues with PWM clock configuration, that the code halts at FaultISR. Please find attached images for clarification. Some help would be greatly appreciated.

Thanks

    Have you not made your call to, "PWMClockSet()" (of PWM0) prior to (before) "ENABLING that PWM0 Peripheral?"

    Writing to any MCU peripheral - prior to it's being enabled (i.e. clocked) - is a "sure route" to the (always dreaded) "FaultISR."

    Test ... (this is a test of the forum's "Reply Increment" function.)    Kindly disregard...

    Note: - Reply Field (instantly & correctly) incremented.     Viewed Field - in stark contrast - remained (impossibly) at ZERO!

    Glad to have assisted - and thank you too - Kurian.     Continue to read/review the "Peripheral Driver Library User Guide" - this proves (almost) as, "Valuable as gold" - and will "ease, speed & enhance" your programming efforts!

    Might you, "Click upon my earlier post," (the one arriving @ 03:28, Nov 28) which properly, "Resolved your Issue."     Best of luck to you & continue to "Make Progress..."
