S32K312 PWM OUTPUT

NITHYANANTHVS — Tue, 09 Apr 2024 10:01:47 GMT

Thank you for your continuous support.

I'm using the API Emios_Pwm_Ip_SetPeriod for setting the period for instance 0 and 1 with the following configurations.

In autogenerated code it mentioned as Set period is only working in OPWFMB mode. For instance 0 OPWFMB mode is supporting, and it is working as per we expected.

But for instance 1, OPWFMB mode is not supporting, and we tried with the following configurations for instance 1.

Using with this configuration, all EMIOS 1 instance channels are not working as expected.

Could you please give the guidance to resolve this.

Awaiting for your response.

Thank you

Hi@NITHYANANTHVS

Emios_Pwm_Ip_SetPeriod->Set PWM using internal counter to a new period. Only DAOC and OPWFMB support.

Please call Emios_Mcl_Ip_SetCounterBusPeriod() for those PWM using master timer bus.

Hi @Senlent

If I use this API Emios_Mcl_Ip_SetCounterBusPeriod(), it will work for first pin only. If i configure more than one pin then the last pin only working remaining pin was not working as expected.

Hi@NITHYANANTHVS

Isn't this the expected result? Because several of your channels use the same Counter bus.
