Temperature Example

The Temperature Example shows how to use the temperature sensor inside the nRF52840 chip and print the measurement.

The application starts with configuring the temperature module and logging module. The main loop reads the temperature sensor and prints measurement every 500 milliseconds.

Tip

Before you start building, remember to set up the nRF5 SDK development environment first. See Setup the nRF5 SDK for details.

Building the example

You can find the source code and the project file of the example in the following folder: examples/nrf5-sdk/temperature.

Open terminal and navigate to the directory with the example Makefile:

cd ./examples/nrf5-sdk/temperature/armgcc

Run make to build the example:

make

Programming the firmware

If compiled successfully, the firmware is located in temperature/armgcc/_build with the name nrf52840_xxaa.hex.

Connect the debugger USB port to your PC using the provided USB-C Cable. A disk drive called M2-DOCK will be automatically detected by the computer.

Run the following command in temperature/armgcc to program the board:

make flash_all

Tip

See Programming section for details about how to program the nRF52840 M.2 Module.

Testing

Test the example by performing the following steps:

  1. Connect the debugger USB port and run a terminal application like PuTTY or screen:

    screen /dev/cu.usbmodem14102 115200

  2. In the terminal window, observe that a temperature value is printed every 500 milliseconds.
