This code shows how to use SAADC to implement a simple voltmeter. It can mesure voltages in single ended and differential mode with 8 ranges.

Do not exceed the permissible voltage range (VSS <= Vin <= VDD) on any input because it may damage the microcontroller.

The user interface consists of small monochrome OLED display and the onboard button.

An additional function is a clock and simple oscilloscope.
