Button Example


The Button Example demonstrates how to get the USER button state with the BSP module.

In this example, there are three actions that can be performed on the USER button:


When the button action is detected, this callback function will be called to notify the button state.


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: pitaya-go/examples/peripheral/button.

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

cd ./pitaya-go/examples/peripheral/button/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.

While pushing the USER button, press the RESET button to enter the DFU mode. Then program the firmware using the nRF Connect for Desktop tool.


See Programming section for details about how to program your Pitaya Go.


Test the example by performing the following steps:

Run a terminal application like PuTTY or screen:

screen /dev/cu.usbmodemD2E39D222D781 115200

Press the USER button and observe the LEDs and output of the terminal.
