Adc_Sar_Ip

Is a Adc_Sar_Ip-example available with a simple one-shot conversion on one channel?

I have S32DS3.5 and RTD S32K3XX 2.0.3.

There is no actually example for Adc for these versions.

Hi @Micha4566465

RTD versions come with 2 examples for ADC:

Adc_Sar_Bctu_Ip_example: The purpose of this demo application is to present basic usage of the ADC_SAR and BCTU IP Driver for the S32K3xx MCU.
The example uses the software trigger to trigger ADC normal and injected conversions, also software trigger from BCTU. The used ADC channel is bandgap (~1.2V corresponding to 7864 with 15 bits resolution at 5v reference). The raw read ADC data will be compared with the provided value.

Adc_example: This application demonstrates the usage of the Adc Driver by Interrupt and DMA Transfer.
The example is divided into 3 parts:

Part 1: Example with SW Triggered One-Shot Conversion Mode, data conversion is updated by Interrupt.
Part 2: Example with BCTU controlled mode conversion by Interrupt.
Part 3: Example with SW Triggered One-Shot Conversion Mode, data conversion is updated by DMA.

Important: S32 RTD is delivered as an Update Site for S32 Design Studio "S32 Design Studio IDE v3.4 Update 3"

Sorry, I am a newbie.

I don't have S32DS 3.4 installed.

The examples of the SW32K3_RTD_4.4_2.0.3 are incompatible with S32DS3.5 as shown in the picture:

Could you create a simple example in S32DS3.5 for ADC for me, so that I can see how to config and use the ADC?

Thanks for your help.

B.R.

Hi @Micha4566465

Could you help me download version 3.4 of S32DS? This will be more useful for you since most of the software developed for S32K3 is for this version of the IDE

Sorry for the inconvenience.
