⏵Hardware and PCB design course: https://www.phils-lab.net/courses
How to write an I2C driver from scratch in C for an STM32F4 microcontroller interfacing with an accelerometer (Analog Devices ADXL355) using the datasheet and ST's HAL (hardware abstraction layer).
Going through schematic, STM32CubeIDE setup, low-level functions, initialisation, setting registers, reading registers, configuring the sensor, reading data, and finally testing the driver.
