Abstract

To implement quick and reliable communication between CAN bus network and computer, we propose a sort of design method of CAN bus network adapter based on CH372, and mainly introduce the concrete implementations of hardware circuit and software program in this article. This system adopts the modularization design, and a new USB interface chip CH372 is adopted in the USB communication module, which can simplify the design of software program. SJA1000 bus controller is adopted in the CAN bus module. The system can effectively implement the data transfer between CAN bus and computer with high speed.
