The Design And Realization Of Multi-Protocol Serial Communication Card Based On DSP

Serial communication is widely used in civil airplane and warplane recently, including HDLC protocol, FTI protocol, Harvard Bi-phase protocol, etc. Serial communication, with multi-interface and multi-protocol for special use, is very important and will find an increasingly wide utilization in all fields. To meet application needs, serial communication card, based on DSP for special use, is designed in this paper.This plan is based on high-performance DSP chip TMS320C6711 as CPU. Combining DSP/BIOS operating system and LabWindows/CVI for test platform, serial communication, in view of the multi-protocol, is brought about.Two-level control is applied in structure. DSP is used for base level control unit, managing peripheral instruments and dealing with data in sending, receiving, storing, etc. Uppering application test software is used for control centre, governing the whole base level hardware indirectly through donimating DSP.Several aspects, involved in this thesis, are as follows. Feasible plan is designed after reading and comprehending related serial communication protocols and datasheets, such as DSP, USC. Driver program, based on CCS, is realized for DSP, which adopts DSP/BIOS and API. Plug&Play deriver program for VXI is achieved based on LabWindows/CVI. Packing for controlling hardware instrument function is completed and universal interface is supplied for the user's second development. According to the application needs, soft panel for PC is designed with the aid of LabWindos/CVI. It provides friendly man-machine interaction for users to control the instrument.
