Getting Started with Zephyr: Devicetree Bindings

Overview In the previous article, “Getting Started with Zephyr: Devicetrees”, we learned how the devicetree describes the hardware on the device in embedded software applications based on the Zephyr project. We illustrated how to describe four LEDs on the nRF52840 development kit (https://www.nordicsemi.com/Products/Development-hardware/nrf52840-dk) in a devicetree. We also learned how to combine multiple devicetree files … Read more
