The Design of CAN/USB Embedded Adapter

Yong Gang Luo

Abstract

In order to realize high-speed and real-time communications between canbus and usb bus, a can/usb embedded adapter is designed in this paper. The hardware of the system consists mainly of AT89S51 as the local processor and PDIUSBD12 as the USB interface device, the sja1000 as the canbus interface device. Data communication is operated by the firmware and drivers. Adapter completely satisfies the needs of the CAN bus with its highest speed of 1Mps and it will be widely used in future for its high efficiency and low cost.
