I2C is a simple and efficient protocol that requires only two wires for communication: a clock line and a data line. It is often used in applications where low-cost, low-power communication is required, such as in sensors, displays, and other peripherals. Any number of slaves and any numbe...
So far, we’ve talked about the basics ofSPI communicationandUART communication, so now let’s go into the final protocol of this series, the Inter-Integrated Circuit, or I2C. You’ll probably find yourself using I2C if you ever build projects that useOLED displays,barometric pressure sensors...

I2C Communication The I2C bus protocol is most commonly used in master and slave communication wherein the master is called “microcontroller”, and the slave is called other devices such as ADC, EEPROM, DAC and similar devices in the embedded system. The number of slave devices is connected ...
Today, through this blog, you will learn all about I2C, its basics and how it works. What will be covered: Interface Characteristics Communication protocol Advantages and disadvantages I2C examples and implementation Without further ado, let us jump right into what is an I²C?

In this tutorial, I’ll show you everything you need to set up an LCD using I2C, but if you want to learn more about I2C and the details of how it works, check out our articleBasics of the I2C Communication Protocol. BONUS: I made a quick start guide for this tutorial that you ca...
Protocol Communication via I2C is more complex than with a UART or SPI solution. The signalling must adhere to a certain protocol for the devices on the bus to recognize it as valid I2C communications. Fortunately, most devices take care of all the fiddly details for you, allowing you to co...
(35ms maximum). The SMBus timeout period dictates a minimum speed of 19kHz for the clock. SMBCLK must be set between 10kHz and 100kHz for proper communication. Either a master or a slave connected to an I2C bus, however, can hold the clock low as long as necessary to process data....
