Battery Status Example

Description

The Battery Status Example shows how to get the status of the battery charger, including the battery level, charging state and power source.

The example initializes the SAADC driver and configures one channel to sample the voltage of the battery. Application Timer module is used to generate a timeout event. When the timer expires, the callback function will be called to print the measurement.

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: pitaya-go/examples/peripheral/battery_status.

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

cd ./pitaya-go/examples/peripheral/battery_status/armgcc

Run make to build the example:

make

Programming the firmware

If compiled successfully, the firmware is located in battery_status/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.

Tip

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

Testing

Test the example by performing the following steps:

  1. Connect a 3.7V Li-Po battery with 2-pin JST-PH connector to the Battery connector.

  2. Run a terminal application like PuTTY or screen:

screen /dev/cu.usbmodemD2E39D222D781 115200
  1. Observe that the battery status is printed every 2 seconds.
