| Abstract: | Space camera controller requires more interfaces and higher processing speed. In order to meet these requirements and realize safe and reliable communication with upper computer, this paper introduces a design method of camera controller based on DSP+FPGA architecture, and choose CAN bus to communicate with upper computer. The realization method of CAN bus communication systems is detailed. The USB bus is used to communicate with computer in order to complete ground testing. Results show that this system ha... |
