SPI (Serial Peripheral Interface) is a serial transmission protocol used for communication between microcontrollers and peripheral devices such as sensors, memories or displays. It is easy to implement and offers high transmission speed, making it a common choice for many embedded systems. In diesem Video programmieren wir SPI mit Zephyr. Wir benutzen als Hardware das Nordic nRF52840-DK und den Sensor Bosch BME280.
