Zephyr and Nordic nRF Connect SDK - 03 Reading a sensor over I²C and a driver (MCP9808)

nRF Connect SDK is the new SDK from Nordic Semiconductor and replaces the old nRF5 SDK. It is based on the Zephyr real-time operating system. Zephyr supports multithreading. The hardware is configured via a device tree and components are activated or deactivated via a configuration file. Internal and external resources such as I²C-bus or sensors can be controlled via drivers. The nRF connect SDK supports the network technologies OpenThread, ZigBee, BLE and Matter. Visual Studio Code can be used as a development environment. In this video we read out the temperature from a Microchip MCP9808 I²C-temperature sensor with Zephyr. We will do this on two ways. First we send direct I²C commands and second we using the devicetree and a sensor driver.
