Nordic Semiconductor already provides reference designs for Altium Designer (R), but if you prefer EAGLE here is a quick guide on how to use the EAGLE reference design. This quick guide assumes you are familiar with doing PCB designs in EAGLE, other...

In a previous blog post, RK has shown us how to use Segger SystemView to monitor a bare-metal application as well as the Softdevice. Based on his work, we will see how to go further and add FreeRTOS to SystemView in order to monitor the RTOS tasks an...

It is exciting to see that in the release of Android Nougat, in addition to 72 new emojis, support for Bluetooth pairing with NFC using the out-of-band (OOB) method is included. By utilizing NFC pairing on Android Nougat, you can avoid the need to ty...

Hey! Wanted to tell you about this free J-Link upgrade for the BBC micro:bit. With the firmware upgrade your micro:bit DAPLink will be transformed into a J-Link OB (on board), while still maintaining the Drag and Drop capabilities that developers c...

Hey! We received 20pcs of a developer edition of the Arduino Primo from Arduino SRL, and we would like to share those with the best and most committed developers on Devzone, before they go on sale! Have you heard about the Arduino Primo board? It i...

The nRF52 Quadcopter is a small miniquad that utilizes the nRF52 as both flight controller and for radio communication. The quadcopter uses the Physical Web and Web Bluetooth to make it as easy as possible for anyone to fly it. This is an open sourc...

A few weeks ago I was experimenting with the nRF52's radio performance and found myself stuck in a routine that consisted of: Tweaking some parameters in a small piece of firmware Recompiling Downloading Running Documenting the result GOTO 1 ...

There are many reasons why you may want to modify the Makefiles that are included in the SDK examples. For instance, if you are invoking Make from the command line then you will probably also want the ability to have Make ensure that everything is up...
