Abstract :
Control System needs high data communication with PC, but transfer speed of traditional serial port protocol RS232, RS485 is slow. A communication system is proposed, which uses high speed digital signal processor TMS320F2812 of TI as control and process core, and uses CY7C68001 of CYPRESS as USB2.0 interface chip, and uses FPGA chip XC3S400 of XILINX as assistant control chip. Detailed hardware interface circuit principle graph and software design method, program flow chart of TMS320F2812 are given. Driver program and application program of PC are discussed, and high data communication is implemented.
