EMIOS PWM configuration in S32K312

SasiKumar_Vengam — Mon, 18 Nov 2024 16:26:24 GMT

i Team,

We are using S32k312 MCU and we tried to configure Emios PWM using S32 Design Studio 3.5. We were not able to generate PWM signals. Please find the configuration in the below attachment and kindly correct if necessary. We are working on Non-Autosar Mode and we are using 6 PWM channels and the channels are given below.

Emios_Pwm_Ip_InitChannel(EMIOS_0,&Emios_Pwm_Ip_I0_Ch4);

// Emios_Pwm_Ip_InitChannel(EMIOS_1,&Emios_Pwm_Ip_I1_Ch0);

Note :- Emios_Pwm_Ip_I1_Ch0 channel can't be able to init successfully. In below function code is getting terminate due to Base->CH.UC[Channel].C value is zero but we have initalized

Emios_Mcl_Ip_Init() fn below and find the config attached image MCL_IP;

}

If we have missed anything, Let us know.

If it is convenient, please send me the simple test project for a quick test.

Hi @robin,
We have configured the PWM correctly using an example uploaded in the Community. We need to configure a GPIO pin as an Interrupt, could you please share any examples on this along with the ISR function implementation.
For your reference, we are using PTB1, PTC8 and PTC9 as GPIO input of the S32K312 MCU.
Thanks.
