A navigation device emulation board based on STM32 microcontroller series is designed which can easily achieve functions that radar navigation interface needs such as ARINC 429 bus data output, digital synchro converter output ( to emu-late head signal output) , DA output ( to emulate deviation distance output) , DO output( to emulate master warn and devia-tion distance flag output) . The board communicates with host computer by using USB bus interface. The architecture of the emulation board is introduced in details. The detailed design of hardare architecture for the board, the USB driver and the STM32 microcontroller series frameware program for the board are discussed. Hardware debugging and real environment tests show that the designed emulation board can fully meet the design requirements.
