Design of multi-functional serial communication card of PC104 bus based-on DSP

Xing Quan Shen

Abstract

In view of the project need, this paper represents the design and test result of the hardware and basic software on a multi-functional serial communication card based on digital signal processor (DSP) . The experiment showed that the system can accomplish serial port data receiving and transmission according to three protocol modes-serial communications interface (SCI), serial peripheral interface (SPI), controller area network (CAN). The circuit is embedded in the host computer conveniently, using the PC104 bus to drive dual port RAM and therefore to realize multi-form serial communication.
