| Abstract: | Combined wireless communication with USB thchnique, a new design for wireless data acquisition system based USB is presented in this paper. The system which consists of converter AD7874, RF transceiver nRF401, MCU 89C51 and USB controller PDIUSBD12 can replace the present complicated wiring and improve the anti-jamming performance and flexibility in data acquisition. The whole project includes the design of A/D converter and wireless USB interface circuit, the firmware of 89C51 and the application program of USB device. |
