Design of multi-channel data acquisition system based on FPGA

Based on the multi-channel data acquisition system with FPGA as the core, The article introduces the control circuit of A/D conversion chip containing FIFO memory in detail. Based on general data acquisition system, this system coordinate FPGA to have a good control of the A/D sampling timing, frequency conversion of multi-channel switch and the programming logic of FLASH memory. With single-chip computer cy7c68013 to realize USB communication, send data to PC for waveform display.
