ADC DEMO

Overview

After starting this application, perform the following actions:

  1. Initialize the ADC

  2. Start a thread to read the internal temperature, chip voltage, and data from channel 0 of the chip within

Environmental Requirements

Please note that there is a corresponding relationship between ADC channels and IO. When configuring, please refer to the definition in wm_adc_channel_t
