WebOverview. 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 ... Web17 mrt. 2024 · Features. VHDL source code of a Inter-Integrated Circuit (I2C or IIC) master component.
