This code example shows how to use the ADC on tinyAVR® 2 Family microcontrollers to measure the internal temperature sensor. In Single mode, when the ADC conversion is triggered, the ADC result is available for a single sample. In this mode, ADC resolution can be selected to be 8-bit or 12-bit. In this example, the ADC is used in Single mode to measure the internal temeperature sensor with 12-bit resolution.

• Download the zip file or clone the example to get the source code
• Open the .X file with the MPLAB® X IDE
• Set the attiny1627-temperature-measure-single-12-bit-adc-mplab-mcc project as Main project by right-clicking on the project title

• Program the project to the ATtiny1627 Curiosity Nano:

  • First clean and build the project by pressing the Clean and Build Main Project button

- Then make and progam the project to the ATtiny1627 by clicking the *Make and Program Device Main Project* button

• To verify that the code is working:

  • Add a Watch to the temperature_in_degC variable found in main.c

- Select the *Watches* tab

- Run code in debugging mode by clicking the *Debug Main Project* button

- Pause the debug session by clicking the *Pause* button

- Now you can read out the latest measurement in the *Watches* tab. Notice that the readout value is in hex format, so remember to convert to decimal value (0x0018 = 24).

This example shows how to use the ADC in single mode to get a 12-bit resolution measurement of the internal temperature sensor on an tinyAVR® 2-series device.
