How To Write A Driver (STM32, I2C, Datasheet) - Phil's Lab #30

⏵Hardware and PCB design course: 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.
