How CAN communication works

Each CAN Bus system needs to have the capacity to link to a PC. This is so that you can debug more easily. The ideal way of doing this is to use a CAN Bus USB interface. It couples the bus to the PC’s USB. The CANUSB gadget we supply accomplishes this with ease for a low cost.

An increasing amount of manufacturers are using CAN Bus. Many are doing so for controlling the electrical inputs on contemporary vehicles. Due to the array of luxurious, high-spec models, CAN is becoming more common. Nonetheless, there are still systems out there that interpret the signals belonging to the CAN Bus. This is to guarantee that the auxiliary light installation operates flawlessly.

Peer-to-peer

For those who don’t know how CAN communication works, it is a peer-to-peer network. There isn’t a master that directs when separate nodes can read and write data on your CAN Bus. At some point, a CAN node shall be in a position to transmit data. When it is, it will inspect the bus to see whether it is busy. Following this, it merely writes a CAN ‘frame’ onto the network. Essentially, the frame that is written is a signal for the CAN as well as every other ECUs existing on the network for it to interpret.

Not every frame shall be relevant

Naturally, the particular frame being conveyed from a single ECU isn’t going to be relevant for every other one. Therefore, every ECU acknowledges whether to reject or accept the transmitted frame. The CAN prioritises ECUs to ensure that you don’t transmit a myriad of frames at once.
