| Abstract: | A fingerprint acquisition system based on TMS320VC5402 is proposed.With 16-bit fixed-point TMS320VC5402 of high-speed processing ability and MBF200 fingerprint gathering card as the core,the fingerprint collection module is designed,in which the USB2.0 peripheral device is adopted for connecting the PC machine.This system could quickly realize fingerprint acquisition,data storage and USB serial communication.Now the hardware and software design of the fingerprint acquisition system is completed,including the debugging of software for USB-and-PC communications.The experiment shows that this design is feasible and relibale. |
