WebAug 16, 2024 · CAN is often used to provide communications between devices in vehicles, like engine management systems, active suspension, ABS, gear shift control, lighting control, air conditioning, airbags, central … 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.

WebAug 19, 2024 · Intra system protocol can be categorized into, I2C Protocol, SPI Protocol and CAN protocol. I2C and SPI are both bus protocol to allow the user for short-distance, serial data transfer. I2C is two wire communication which made by the Philips (Nowadays NXP) and SPI is made by the Motorola. WebNov 5, 2024 · You can see ethernet cable pairs as a current loop, driven by transformers on both ends. CAN is a single-line bus (1 pair) with packet collision handling. Ethernet is a multi-line bus, usually at least an RX and TX pair but it can be more depending on the CAT. CAN requires a termination resistor on both buses ends. popular beetle ポート番号 https://chiriclima.com
