# Example: ADC1
This test code shows how to configure ADC1 and how to use ADC1 get the voltage.
This test code shows how to configure ADC1 and read the voltage connected to GPIO pin.
####ADC1 functions:
* ADC1,CHANNEL_4:GPIO32, voltage range [0v,3.1v],the Data range [0,4095]
####Test:
* Please connect the test voltage to GPIO32
### ADC1 functions:
ADC1_CHANNEL_6: GPIO34, voltage range [0V..3.1V], the data range [0..4095]
### Test:
Please connect the test voltage to GPIO34
