ADC Example
=====================

Overview
--------------------

This is an example of SARADC. SARADC convert analog signal to digital.

It use defalut configuration to demonstrate the function of ADC.

If you make all-app.bin based on this project,it will execute an ADC sampling task according to the configuration set in adc_main.c


Hardware Requirements
-------------------------------

This project is able to run on any commonly available Beken development board.
You should add an analog signal,such as voltage,to GPIO25.
Then read the average ADC value from log. 



Build
***************************

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

Flash
***************************

See the Getting Started Guide:ref:`project_get-started:` for full steps to configure and use Armino to build projects.
