S32K312 ADC Channel mapping

[sungjun]

hello? NXP Team
I am currently using S32 Design Studio for S32 Platform 3.4.
The MCU is S32K312, and I am curious about how to set up the ADC channel.

To set up the ADC in S32 Design Studio for ARM Version 2.2,
Just set the Input Channel according to the Name in the Configuration list as shown below.

What screens can I refer to in S32 Design Studio for S32 Platform 3.4?

And what information in S32K3xx_RM should ext_in refer to in the ADC setting signal?

Lastly, I would like to know the meaning of ADC0_X[0] and ADC0_MA[2:0] = 3'h0 in the picture below.

It's a hassle, but please explain in detail.

Thank u!

Hi @sungjun 

What screens can I refer to in S32 Design Studio for S32 Platform 3.4?

We recommend using the newest S32DS version (3.5) with the latest S32K3 software (RTD 4.0.0) releases. To understand how the ADC can be configured with ConfigTools please use the examples provided with the RTDs. 

And what information in S32K3xx_RM should ext_in refer to in the ADC setting signal?

This pin corresponds to the ADC1_X[1]. You can consult the assignment in the S32K312_IOMUX attached to the S32Ke reference manual. 

Meaning of ADC0_X[0] and ADC0_MA[2:0] = 3'h0. 

Check the following community thread. It has information related to the topic.
