Research of method for testing ARINC429 bus

This paper first makes a brief overview of testing air bus. Then it mainly discusses the ARINC429 bus analyzer's hardware design and software programs. On hardware, the C8051F064 MCU and HS3282 are used in this analyzer to design the 429 bus interface circuit. On software design, this paper mainly introduces the 429 signal's receiving and sending subroutines, and various electrical characteristic parameters' measurement algorithms of 429 signals. The innovative point of this 429 bus analyzer is that it can not only test the data content of 429 bus signals, but also can measure various electrical characteristic parameters in order to monitor the ARINC429 bus much more better.
