I2c long form

WebbI2C stands for Inter-Integrated-Circuit communications, it's meant for short distances on a PCB or subassembly. But, hey, we're engineers, and we like to push the limits of technology, right? So why not try to have I2C run over a meter long cable, or even longer? WebbI2C is a two-wire protocol for communicating between devices. At the physical level it consists of 2 wires: SCL and SDA, the clock and data lines respectively. I2C objects are created attached to a specific bus. They can be initialised when created, or initialised later on. Printing the I2C object gives you information about its configuration.

WebbOverview. I2C is a serial, synchronous, half-duplex communication protocol that allows co-existence of multiple masters and slaves on the same bus. The I2C bus consists of two lines: serial data line (SDA) and serial clock (SCL). Both lines require pull-up resistors. With such advantages as simplicity and low manufacturing cost, I2C is mostly ... Webb12. I have a project that requires to do I²C/I2C/TWI over a long distance (30 to 40 meters).
