ADC Example

This example shows the use of the espp::OneshotAdc and the espp::ContinuousAdc components.

It uses the following components:

• adc
• logger
• task

These adc components can be used to read analog values using the ESP's built-in ADC hardware, supporting DMA and filtering as well.

How to use example

You can build and run this example on any esp dev board, such as the QtPy ESP32 series, the TinyPICO / TinyS3 boards, the WROVER-DevKit, and the ESP32-S3-BOX. Make sure to set the idf target when building the example.

Build and Flash

Build the project and flash it to the board, then run monitor tool to view serial output:

idf.py -p PORT flash monitor

(Replace PORT with the name of the serial port to use.)

(To exit the serial monitor, type Ctrl-].)
