| Abstract: | A design method of protocol conversion unit that is based on AVR AT90S8515 chip micro controller, CAN bus controller SJA1000 and dual RS 232 receiver/transmitter MAX232 is described. A communication bridge between RS 232 and CAN bus is constructed, which makes it possible to communicate between PC and terminals on the CAN bus. The hardware circuits, software design, design flow chart and the initialization program are given. |
