Also to know is, what is the difference between i2c and SPI?

I2C is the basis of the CAN bus. SPI (Serial Peripheral Interface) is a 3-wire, full duplex, master-slave serial bus. The main difference from I2C is that the lines are actively driven, so it can operate at much higher speeds. SPI has no such overhead or clock limitations, so it can be 80 or 100 times faster than I2C.

Similarly, is i2c full duplex? The I2C protocol is inherently half-duplex, while the SPI protocol is inherently full-duplex. So with SPI, every read is also a write. This could in theory double the speed of the bus, however, when implementing the SPI protocol we noticed that most of the time we didn't have data to send one direction.

In this way, is i2c faster than serial?

I2C communication So based on this information I've concluded that the fastest common bit rate used for the serial communication is 115200 bits/s. This seems to be significantly lesser than the bit rates for I2C, which appear to start at 100 kbit/s which equates to 100000 bits/s.

CAN and SPI difference?

The biggest difference between CAN and SPI is that the CAN protocol defines packets. In SPI (and serial interfaces in general), only the transmission of a byte is fully defined. Given a mechanism for byte transfer, software can provide a packet layer, but no standard size or type exists for a serial packet.
