How Does the I2C Interface Work in PCF8514T?
Basics of I2C Communication
The I2C protocol uses two lines,
SDA (Serial Data)
SCL (Serial Clock)
to send data between devices. Each device on the I2C bus has a unique address, allowing communication between multiple devices with minimal wiring.
Data and Clocklines in Action
SDA carries the actual data, while SCL provides the clock signal. This makes I2C a synchronous communication protocol, meaning data transfer is in sync with the clock pulse, reducing errors.
