Rust Embedded for STM32 Microcontrollers: I2C protocol
The sixth video of the Rust Embedded course.
In this video you will learn:
What is I2C protocol.
The order of operations in I2C protocol.
The most important features of I2C protocol.
How to read data from the LSM303 magnetometer located on the F3Discovery board.
How to make sure that you I2C communication is functional.
What is open-drain and pull-up resistor, and how to find them on electrical schematics.
How to use reference manuals of external sensors.
