There are 1 incomplete or pending task to finish installation of Semantic MediaWiki. An administrator or user with sufficient rights can complete it. This should be done before adding new data to avoid inconsistencies.This article explains what is the I2C and how to use it through examples
Target description
Following this tutorial, you will:
- Get familiar with the STM32L476RG Nucleo board,
- Learn how to program and use a I2C
Hardware
The hardware requirements to start the application are the following:
- 2 boards STM32L476RG [1] board
1. I2C
I²C (Inter-Integrated Circuit) is a two-wire serial communication system used between integrated circuits which was originally created by Philips Semiconductors back in 1982.
The I2C is a multi-master, multi-slave, synchronous, bidirectional, half-duplex serial communication bus.
1.1. I2C Overview
- SDA (Serial Data) is the line where master and slave send or receive the information (sequence of bit).
- SCL (Serial Clock) is the line dedicated to the clock to synchronize the data flow.
2. Create the project in STM32CubeMX
