Design of data acquisition system based on FPGA

A set of data acquisition system which combined characteristics of high speeding FPGA was developed. The internal logic of FPGA was used to control time sequence. It took FPGA as the core to read the acquisition data, show and transmit data by USB interface. The system has a simple circuit structure, low power consumption and so on. It can be used as the acquisition system of pressure voltage, temperature parameters, voltage and current.
