Raspberry Pi Pico (RP2040) I2C Example with MicroPython and C/C++ | Digi-Key Electronics

Inter-Integrated Circuit (I2C) is a common communication protocol used by many microcontrollers and sensors to pass data back and forth. It relies on 2 pins for communication: - Clock (SCL) - Data (SDA) The pins to control these lines are required to be open drain in order to support more than 2 devices on the bus. As a result, external pull-up resistors are required on the lines. The sensor breakout board we use in the video already contains these resistors, so you do not need to provide your own. In this video, we show you how to use I2C from the Raspberry Pi Pico to communicate with an ADXL343 accelerometer. We give an example in MicroPython as well as C/C .
