基于FPGA的429总线编码的发送

Design of ARINC429 bus transformer based on FPGA

ARINC429是定义航空电子设备和系统彼此之间相互通信的一种规范,本文介绍了基于FPGA的429总线编码发送电路,该电路利用XILINX公司的SpartanⅡ系列大规模现场可编程阵列芯片(FPGA) XC2S100实现与429计算机的通信,采用特殊电路完成符合429编码格式转换后发送,文章说明了电路各部分的设计和工作原理。

ARINC429 is a principle of communication between aerial electronic equipments and systems.This paper introduced a 429 bus coded transmitting circuit based on FPGA.By applying the large scale Field Programmable Gate Array (FPGA) XC2SIO0 of the SpartanⅡSeries produced by the XILINX Co,the circuit communicated with 429 computer and send serial codes in a way that meet the necessity of 429 coded mode after voltage transition,the operating and designing principles of each parts was explained.
