Embodiment Construction
[0034] The invention provides a general interface controller for spacecraft, which uses ARINC659 bus and UART interface as the standard bus interface, wherein the ARINC659 bus is used as the "time trigger" standard backplane bus, which has extremely high reliability and fault tolerance, and the UART interface is used as the The "event trigger" interface is simple and easy to use. The universal interface controller of the present invention can realize communication with the processor through any one of the ARINC659 bus or the UART interface. The configuration of the communication interface of the device, specifically as figure 1 shown.
[0035] The universal interface controller of the present invention uses the ARINC659 bus as the communication interface, or uses the UART interface as the communication interface, and is controlled by the interface selection control signal. When the interface selection control signal is high level, the ARINC659 bus is selected as the communica...
