In terms of ADC, it is known as ADC2_CH3, and ADC2 is said to be conflicting with wifi operation. Common wisdom on the Internet is to avoid attempting to use channel 2 ADC together with Wi-fi -- I couldn't even find any success reports. The battery examples in this repo are, ...

② When I configure reading the raw data of ADC_CHANNEL_2, ADC_CHANNEL_7, ADC_CHANNEL_8, ADC_CHANNEL_9, there is an initial value in the first ADC_CHANNEL of the configured channel array. If I input an analog signal on this channel's pin, the value of the analog signal will be ...
