The design of interface circuit based on the
TMS320C5410 DSP
Abstract: The lesson adopt a HD7279A chip as the main control apparatus of the exterior interface circuit , then use TMS320C5410 DSP controlling exterior interface circuit inderectly by controlling HD7279A . Exterior interface circuit including keyboard and manifest interface circuit . first , the lesson showed the development and the application field of DSP in our country , analysised the main researching duty of the lesson , and also the prupose and the meaning of this graduate disign . then showed the basic concept , interrupt system , serial interface , Function characteristics of TMS320C5410 DSP , then according to the content of this lesson , showed a kind of new keyboard and manifest interface circuit chip , HD7279A . finally, make the hardware and software design of the whole needed system based on the basic mission of this design , additionally introduced the visual compositive exploitation tool CCS of DSP.
The thesis completed the basic hardware and software programme design and PCB theory design.
In hardware design aspect , set up a serial communication mode by utilizing MCBSP interface circuit of DSP and HD7279A , control keyboard and display of the system by controlling HD7279A.
In software design aspect , translate,debug and run the programme by using compositive exploitation tool CCS .
