There are two roles in the operation of I2C, one is “Master”, the other is “Slave”. Only one Master is allowed, and can be connected to many Slaves. Each Slave has its unique address, which is used in the communication between Master and the Slave. I2C uses two pins, one is fo...
This article has compared all three communication interfaces, including their advantages, disadvantages, and uses.
Data transmission between digital devices can mainly occur in two ways, parallel or serial through a wired medium. Microcontrollers use many serial protocols to communicate with external devices such as sensors and displays and I2C communication is one of them. A language in which a mode of commun...
The exercise of I2C COMMUNICATION is divided by the following two demos 实验一 Demo 1 两块板子连接的端口需要为SCL与SDA对应连接 SDA 负责数据传输 SCL 负责时钟控制 Uno与Nano的SCL与SDA端口如图所示 The port of connection between these two boards is the respectively corresponding connection of SCL and...
I2C Arduino I2C communication can also be used between two Arduino boards or other devices. I2C makes connecting sensors and displays together with the Arduino simple as it only involves two wires and it can reduce pin counts too even with numerous devices on the bus ...
The Arduino sketches associated with these projects had the I2C setup built in by using Arduino sketches from sensor developers, so the user doesn't really get into details on the I2C operation. But I2C can also be used to communicate between the Arduino and the EV3 Intelligent Brick, passing...
Arduino I2C Raspberry Pi Communication example between arduino and RPi with JSON, avoiding the 32 byte limitation of I2C. RPi acts as master, arduino as slave, and the communication is made through several request: RPi asks for data length to arduino. Arduino answers with the JSON length. RPi...

I2C总线的Arduino库函数 I2C即Inter-Integrated Circuit串行总线的缩写,是PHILIPS公司推出的芯片间串行传输总线。它以1根串行数据线(SDA)和1根串行时钟线(SCL)实现了双工的同步数据传输。具有接口线少,控制方式简化,器件封装形式小,通信速率较高等优点。在主
2 Arduino or Genuino Boards hook-up wires Circuit Connect pin 4 (the data, or SDA, pin) and pin 5 (the clock, or SCL, pin) on the master board to their counterparts on the slave board. Make sure that both boards share a common ground. In order to enable serial communication, the...
