For most programmers, a C or C++ program’s life begins at the main function. They are blissfully unaware of the hidden steps that happen between invoking a program and executing main. Depending on the program and the compiler, there are all kinds of interesting functions that get run before main, automatically inserted by the compiler …

Nordic has released a nRF52840 Preview Development Kit (PDK) to support their new nRF52840 chip. Unlike the Thingy:52 and nRF52 DK, the Preview DK supports the new long-range LE Coded PHY, making it fully Bluetooth 5 capable. The Preview DK also supports 802.15.4 for the Thread communication protocol. This kit is similar to the nRF52 …

The Thingy:52 development kit is a a fully-loaded sensor platform that is ready for web and app connections. Like the nRF52 DK, the Thingy:52 platform is built on the nRF52832. The nRF52832 is Bluetooth 5 ready, although it does not support the new long-range LE Coded PHY. The Thingy:52 development kit is designed for developing …

This is a great platform for learning more about BLE and the ARM Cortex-M4 architecture. It seems as if every company I've worked with in the past 6 months is using the Nordic nRF5x. The nRF52 is an "ultra-low power" SoC consisting of a Cortex-M4F MCU with an integrated 2.4GHz transceiver. Nordic also supplies software …

This is a great platform for learning more about BLE and the ARM Cortex-M0 architecture. It seems as if every company I've worked with in the past 6 months is using the Nordic nRF5x. The nRF51 is an "ultra-low power" SoC consisting of a Cortex-M0 MCU with an integrated 2.4GHz transceiver. Nordic also supplies software …

The Crazyflie is much more fun than your typical development kit, as it involves a small flying drone! This is a great example of a complex system with multiple processors that interact. The Crazyflie2 utilizes BLE and a custom Nordic radio protocol (Enhanced Shockburst) for communicating with a phone or host PC. The Crazyflie has …
