DeviceTree Overlays on Zephyr RTOS: Adding I2C or SPI

January 14, 2023 Craig Peacock 0

After 18 months developing with the Zephyr RTOS, I’m starting to become a strong proponent. In my opinion, one of the key advantages of the Zephyr RTOS is the hardware abstraction. It allows applications to be written for Zephyr that are platform independent and can be moved between different boards including different manufacturers of microcontrollers. In a world still suffering from chip shortages, it has been a breath of fresh air. The Zephyr application (project) contains the application source code while the board files detail the hardware and GPIO assignment, or essentially, how the printed circuit board is wired. This …
