What are the major differences between I2C and SPI busses list some components that use each of them?

I2C is a two wire protocol and SPI is a four wire protocol. I2C supports clock stretching and SPI does not have clock stretching. I2C is slower than SPI. I2C has extra overhead start and stop bits and SPI does not have any start and stop bits.

What is UART I2C and SPI?

Communication protocols such as UART, SPI, and I2C provide an essential function in embedded systems. They function as an interface between a microcontroller and a peripheral to allow the devices to communicate with each other and the external world.

Which one is better I2C or SPI?

Overall, SPI is better for high speed and low power applications, while I2C is better suited for communication with a large number of peripherals, as well as in situations involving dynamic changing of the primary device role among peripherals on the I2C bus.

What are the advantages of SPI over I2C?

SPI is better for high speed, low power applications. I2C is better suited for communication with a large number of peripherals. Both SPI and I2C are robust, stable communication protocols for embedded applications that are well suited for the embedded world.

What is UART What is the difference between UART and I2C?

UART is typically for a point to point connection, I2C is a bus protocol. UART is not a protocol (see also remark of Justme below), I2C is a protocol. UART does not have a master/slave principle (no protocol), I2C has. UART can be used for transmission over distance, I2C is not meant for that.

What is SPI in embedded system?

The Serial Peripheral Interface (SPI) is a synchronous serial communication interface specification used for short-distance communication, primarily in embedded systems. The interface was developed by Motorola in the mid-1980s and has become a de facto standard.

What is difference between CAN and I2C?

CAN is a message based protocol, designed specifically for automotive applications for the communication between the main host controller and other devices (also now in industrial automation ). It can be transferred to long distances. I2C is a short distance communication used between the ICs in a same circuit.
