ARINC429 bus communication assembly and method based on interrupt notification

The invention discloses an ARINC429 bus communication assembly and method based on interrupt notification, and belongs to the field of data communication. Comprising a CPU used for controlling the working mode of the ARINC429 protocol chip, performing LABEL filtering and parity check, sending data, obtaining a receiver ID of the ARINC429 protocol chip receiving data from an interrupt management module, and receiving and storing data read from the ARINC429 protocol chip corresponding to the receiver ID; the interrupt management module is used for outputting a GPIO (General Purpose Input/Output) interrupt to a CPU (Central Processing Unit) when the ARINC429 protocol chip receives data, recording a receiver ID (Identity) of the data receiving chip, and sending the receiver ID back to the CPU when the CPU reads information; and the ARINC429 protocol chip is used for working according to the configuration of the CPU, sending data needing to be transmitted by the CPU to external equipment, receiving the data sent b
