Power Profiler Example

Description

The Power Profiler Example demonstrates how to place the board into a minimum power consumption state and measure the power consumed.

This example application starts up, sends the Deep Power-down (DP) instruction to the QSPI flash memory, disables the Wi-Fi module, and enters the System OFF mode. The power consumed can be measured by using a digital multimeter.

Tip

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

Hardware Prerequisites

  • 1x Pitaya Go board
  • 1x Digital Multimeter
  • 1x DC Power Supply
  • 1x 2-pin JST cable

Building the example

You can find the source code and the project file of the example in the following folder: pitaya-go/examples/peripheral/power_profile.

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

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

Run make to build the example:

make

Programming the firmware

If compiled successfully, the firmware is located in power_profile/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

Measure the power consumed by performing the following steps:

  1. Follow the figure below to setup the hardware for current measurements:

  2. The current measurements can be done over Digital Multimeter once the current remains constant.
