Abstract

The design of a communication module between USB and CAN bus based on CAN controller of DSP and USB chip is presented.A scheme that implements the connection between CAN bus network and the computer by USB interface is proposed..With the help of USB100,it can update the RS232 serial port of a computer to USB interface in the situation of unknowing anything about USB protocol.The hardware of system is extremely simple as a result of using CAN controller on DSP chip.Under the control of DSP,PC and CAN node can communicate with the baud rate of 1 Mb/s.The data transmission is stable and reliable.The experimental results show that the system of CAN bus communication made up of eCAN module which is on the chip of TMS320F2812 is simple and much more practical.
