system_adc1_read not available ?

[jumjum123]

Following ESP32_RTOS_SDK_API reference, system_adc11_read is the way to read analog values from GPIO pins.
What do I need to to, to get it running. Right now I cannot find a header file or something else.

We are all waiting eagerly for documentation and drivers for ADC/RTC systems.

Hi,

I am working on ESP32 Demo V2 Board and I connected one temperature sensor on ADC2_CH4 Pin. I have also looked into User manual of ESP32 to check how to read ADC2 readings but not found any informations for that.

Does anyone has any idea or informations to read ADC2 CH4 reading from ESP32?

I am using ESP-idf RTOS 0.9 SDK for my development purpose.

Please let me know if anyone has idea or clue for that.

Regards,

Hi,

We have connected one Temperature Sensor on ADC_CH4 pi as ADC Input Pin and i want to read ADC Readings from that pin.

So, Does anyone has any idea or API to read that value?

Sorry, the API is not in esp-idf yet. We are working to get all hardware supported, but that is not something that will happen in a few days.
