Design of SPI bus communication in the multi-channel data acquisition systems

摘要：

　　the system structure of a multi-channel data acquirement system is introduced in this paper.The communication interaction circuit between the main control system and signal conditioning circuit is described.The SPI bus communication type is adopted between C8051F320 and FPGA.The speed and accuracy of datum transfer must be considered in the communication design,so the CRC calibration is used.

关键词： signal acquirement SPI communication CRC calibration FPGA.
