Blinky Example


The Blinky Example demonstrates how to configure the GPIO pins to drive the LEDs.


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

Building the example

The source code and the project file of the example are located in the following folder: examples/nrf5-sdk/blinky.

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

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

Run make to build the example:


Programming the firmware

After compiled, the firmware is located in blinky/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 blinky/armgcc to program the board:

make flash_all


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


After programmed, the application will run automatically. Observe that the LEDs will start to blink as shown in this figure:
