I2c explanation
I2C combines the best features of SPI and UARTs. With I2C, you can connect multiple slaves to a single master (like SPI) and you can have multiple masters controlling single, or multiple slaves. This is really useful when you want to have more than one microcontroller logging data to a single memory card or displaying … Visa mer With I2C, data is transferred in messages. Messages are broken up into framesof data. Each message has an address frame that contains … Visa mer 1. The master sends the start condition to every connected slave by switching the SDA line from a high voltage level to a low voltage … Visa mer Multiple masters can be connected to a single slave or multiple slaves. The problem with multiple masters in the same system comes when two masters try to send or receive data at the same time over the SDA line. To … Visa mer Because I2C uses addressing, multiple slaves can be controlled from a single master. With a 7 bit address, 128 (27) unique address are … Visa mer WebbI2C 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 number of masters can be connected to these 2 signals.

I C (Inter-Integrated Circuit; pronounced as “eye-squared-C”), alternatively known as I2C or IIC, is a synchronous, multi-master/multi-slave (controller/target), packet switched, single-ended, serial communication bus invented in 1982 by Philips Semiconductors. It is widely used for attaching lower-speed peripheral ICs to processors and microcontrollers in short-distance, intra-…
