How does CAN differ from I2C?

Most MCUs with i2c buses can only go upto 400 kHz. CAN is differential, and is more immune to noise. CAN only allows 8 bytes to be sent at a time, i2c is essentially unlimited (this can be good or bad depending on how you look at it). You can broadcast with i2c, although i2c uses node addresses for most messages.

What is similarity between I2C and SPI protocol?

About the SPI Like I2C, it is also has a master-slave architecture but it is a 4+ wire bus. SPI requires a clock line (SCK), two data lines for transmitting data bidirectionally known as the MOSI and MISO lines. Additionally, there must be a slave select (SS) line for each slave on the bus.

What is I2C and protocols?

I2C stands for Inter-Integrated Circuit. It is a bus interface connection protocol incorporated into devices for serial communication. It was originally designed by Philips Semiconductor in 1982. Recently, it is a widely used protocol for short-distance communication. It is also known as Two Wired Interface(TWI).

What is the difference between I2C and SPI communication protocol?

The important difference between I2C and SPI ( I2C vs SPI ) communication protocol. I2C can be multi-master and multi-slave, which means there can be more than one master and slave attached to the I2C bus. SPI can be multi-save but does not a multi-master serial protocol, which means there can be only one master attached to the SPI bus.

What are the limitations of the I2C protocol?

I2C protocol has some limitation for the number of slaves, the number of the slave depends on the capacitance of the I2C bus. It only provides a few limited communication speed like 100 kbit/s,400 kbit/s, etc. In I2c, devices can set their communication speed, slower operational devices can delay the operation of faster speed devices.

What is the SPI protocol?

SPI was developed in the 1980s by Motorola as a way to communicate between their early microcontrollers and onboard peripherals, such as EEPROM. Motorola, nor any other organization, maintains any sort of standardization of the SPI protocol. As a result of this “de facto” standard, implementations can vary from manufacturer to manufacturer.

What is the iri2c protocol?

I2C is a two-wire serial protocol for connecting low-speed devices such as microcontrollers, EEPROMs, Analog to Digital (A/D) and Digital to Analog (D/A) converters, Input/Output (I/O) interfaces and other similar peripherals in an embedded system.
