| Abstract: | The paper introduces a design of data acquisition and control card based on USB interface. The entire system is mostly composed of six parts: USB interface chip ,MCU,A/D,D/A,counter and DIO. The host computer can control the read or write of the USB interface,data acquisition, D/A and data transmission, et al. In this paper, the principle and application of USB interface chip CH371, ADS7825 and LTC1450 are presented in detail. The host computer software is designed in MFC. |
