Design of data collection and transmission system based on AD7865

This paper introduces a high-speed multi-channel data collection system based on AD7865 which can transmit data to PC by USB interface chip CY7C68013. Not only focusing on the character of the AD7568, this design but also complete the work of interface circuit and the programming of the whole system centered on the FPGA EP1C6Q240C8. By controlling the variation of the signal from analog to digital, the system achieves the point of the high-speed multi-channel data collection and real-time monitoring, it can be primly used in photoelectric detection system.
