#83489 - Rs485 vs CAN Responding to: ???'s previous message |
Firstly, You need a micro with CAN in order to do CAN. With RS485 you just need a micro with a uart (much more common & cheaper), in fact you can bit-bash the uart if REALLY pressed. The payload size of CAN was 8 bytes - this maybe larger in CAN 2.0 - this maybe an issue. You need CAN interfaces for your PC (if that is required). Personally, I've never used CAN as I have not had a need to. RS485 addresses most of the requirements I need and is simple to implement with standard micros. Horses for courses, it is said! If I was doing a automotive project, one would most likely use CAN or LIN as these are standards in this field. I would say that CAN is best suited to applications that have a number of devices that transfer small amounts of data regularly. |
