I2C is a common communication protocol that is used in a variety of devices from many different product families produced by TI. This application note begins with a basic overview of the I2C protocol, describing the history of the protocol, different I2C speed modes, the physical layer of the digital communication, and the structure of the data.
13 lut 2016 · The I2C communication protocol combines the best features of SPI and UART. This guide will show you how it works in an easy to understand format.
Today, at the low end of the communication protocols, we find I²C (for ‘Inter-Integrated Circuit’, protocol) and SPI (for ‘Serial Peripheral Interface’). Both protocols are well-suited for communications between integrated circuits, for slow communication with on-board peripherals.
The I2C bus is a very popular and powerful bus used for communication between a master (or multiple masters) and a single or multiple slave devices. Figure 1 illustrates how many different peripherals may share a bus which is connected to a processor through only 2 wires, which is one of the largest benefits
By definition, Inter-Integrated Circuit (I 2 C)—also known as Inter IC—is a hardware communication protocol that uses synchronous communication with a multi-main, multi-node, and serial communication bus. Synchronous communication means two (or more) devices exchanging data share a common clock line.
Integrated circuits are the little black "chips", found all over embedded electronics. An IC is a collection of electronic components -- resistors, transistors, capacitors, etc. -- all stuffed into a tiny chip, and connected together to achieve a common goal.
Different goals between analog and digital communication systems: • Analog communication systems: to reproduce the transmitted waveform accurately. ⇒ Use signal to noise ratio to assess the quality of the system. • Digital communication systems: the transmitted symbol to be identified correctly by the receiver.
