rs232 vs can
there are no limit to rs485 speed , Maxim Max485 work at 2.5Mbps, my opinion is that Canbus is the effect of globalization, the electric layer is similar to rs485, only difference is the protocol. in rs485 i make multimaster without problem, i can control conflict on the bus,I'm free to implement my protocol in anytype of microcontroller and I'm free to make application in any PC language
jelydonut said the few company use it, but is false, the industrial world is full of the rs485 devices.
The CanBus ig Germany concept, and I speak for experience (my wife is germany), the germany's mind can make complicate the simple!!!
