Abstract

A designed method of USB-CAN converter with PIC18F4580 is proposed in this paper. A CH372 is used to communicate computer and microcontroller as a bridge. The CAN interface controller is realized by the ECAN module embedded in PIC18F4580. PCA82C50, one chip of CAN bus driver, is used as interface between the CAN protocol controller and the physical bus. A dynamic link library is designed with Visual Studio 2003 platform. With the converter and the DLL, a computer could work with a CAN network as one CAN node.
