S32K118 EVB SDK 4.0.2 Change pin function during runtime

[JakubPyznar]

Hi,

I am currently working on a S32DS project for S32K118 EVB with SDK 4.0.2 included. I cannot find in mex configuration or in drivers files how to change pin mode in runtime. I need to change pin mode from default GPIO output to ADC input and back.

Best regards

Hi 

Have a look at the PINS_DRV_SetMuxModeSel (hello_world_s32k118_SDK402/SDK/platform/drivers/src/pins/pins_driver.c)

Best Regards,
Robin

So I have to initialize ADC pheriperal and desired pin as an GPIO output, and then I can change its function at any time?
Now I see that in S32K118_features.h there is a macro FEATURE_PINS_HAS_ADC_INTERLEAVE_EN which is defined as (0), so I am not sure it would work. It seems like it is not available on this chip. Any other ideas?

You need to initialize ADC peripheral and GPIO output. But before ADC sample that channel, please change the pin from GPIO output to ADC input.
Since S32K11x does not support ADC interleave channel, the macro FEATURE_PINS_HAS_ADC_INTERLEAVE_EN defined as (0).
