ADCs Configuration/usage on the Radxa Zero V1.5

I am reaching out to seek information regarding the configuration and usage of Analog-to-Digital Converters (ADCs) on the Radxa Zero V1.5 board.

I have been unable to locate detailed documentation or resources specific to ADC configuration on the Radxa Zero V1.5. I have thoroughly searched through the available documentation and forums, but the information seems to be limited.

Could anyone provide guidance or point me in the right direction on how to set up, read, and use the ADCs on the Radxa Zero? Any details regarding ADC pin configurations, necessary kernel modules, device paths, or sample code snippets would be immensely helpful.

I appreciate your time and assistance in advance.

Thank you for your support,

Best regards

I am trying to use the pin 15 SARADC_CH1 but it is not working.
