ARINC 429 Receiver

This project receives differential ARINC 429 and converts it to asynchronous RS-232. The hardware is pretty simple, as all the magic happens inside the FPGA. Power is derived from the serial cable, allowing a conventional USB converter to be used. Label filtering and parity are software selectable, and all received data is timestamped with a 1ms accuracy. The PCB was sealed with clear heatshrink, ensuring the status LEDs were visible. The JTAG header is also accessible allowing firmware upgrades.
