S32K312 PWM Generation issue

NITHYANANTHVS — Wed, 27 Mar 2024 03:13:30 GMT

Hi Team,

@Senlent

I've loaded PWM generation example code for s32k312 and tested. It was working as expected.

The example code versions are below and also please find the attached screen shots

Version 3.5
SDK 2.0.0

I Created a new application project using below configuration.
Version 3.5
SDK 3.0.0

Here, it is not working as expected.

If I configure one channel it was working and we could able to see the correct frequency & duty cycles in the scope, but if I configure more than one channel, the last one only working as expected. The first two channels are not working.

Emios_Pwm_Ip_SetDutyCycle is disabled in generated code.

Please guide here if someone is aware of it.

Thank you

Hi @Senlent

Thank you for your continuous support!

We were tested your example code. We are using this configuration, but we can't be able to achieve the result.

It is not working as expected. If I configure one channel it was working and we could able to see the correct frequency & duty cycles in the scope, but if I configure more than one channel, the last one only working as expected. The first two channels are not working. Please guide here if someone is aware of it.

IDE Version - 3.5

SDK version - 3.0.0

If I call continuously in IDE version 2.0.0, it is working as expected.

Thank you

Hi @Senlent

Here we were configuring PWM output for three channels. For Duty cycle they are configuring with channel id. Eg: Emios_Pwm_Ip_SetDutyCycle(INSTANCE_0, 0U, 6750);

But for period they didn't configure for each channel. Could you explain the following queries.

Hi @Senlent

Thank you for your support!

I couldn't be able to provide you a project. Because it causes violation for me.

I'm configuring in 2.0.0 SDK version it was working fine as expected, but one problem in 2.0.0 SDK version, we couldn't be able to generate ADC pins. It is not reflecting in board -> Siul2_Port_Ip_Cfg.c file. (Pin list only generated, array of pin configuration structure not generated)

Is there any other solution for this problem or i need to install any other packages for 2.0.0 SDK version for ADC pin generation.

Awaiting for your response.
