I2c vs spi different between

Question

Accepted Answer

I2C and SPI are two different communication protocols used in embedded systems.

I2C (Inter-Integrated Circuit) is a multi-master, multi-slave protocol with a slower data rate compared to SPI.
SPI (Serial Peripheral Interface) is a full-duplex, synchronous protocol with higher data rates but limited to one master device.
I2C uses two wires (SDA and SCL) for communication, while SPI typically uses four wires (MISO, MOSI, SCK, and SS).
I2C is more suitable for applications requiring multiple devices to communicate on the same bus, while SPI is better for high-speed communication with a single device.
I2C devices have unique addresses assigned to them, while SPI devices are selected using a chip select (CS) line.
