| Abstract: | In order to overcome the inherent defects of MCU and satisfy the demands of astronautic control, the paper puts forward how to realize CAN bus communication by utilizing FPGA to control the CAN controller SJA1000 which works in the inquiry mode. The hardware structure, chip selection, and composition principle of the device are discussed. The control process of FPGA is analyzed and designed. The test results show that the system satisfies all the requirements of CAN bus communication. The system which has decreased the volume,weight and power consumption has its own advantages compared with the conventional system based on MCU. The design has been applied to the ground test equipment of satellite - born electrical field mill successfully. |
