ARINC429 BUS Interface Based on HS-3282 and CPLD

基于HS-3282和CPLD的航空总线ARINC429接口,HS-3282芯片由2接收器和1发送器组成。HS-3282和8位单片机间的接口逻辑全部在单片CPLD中实现。系统发送数据时,将数据存入发送缓冲区,由通信模块将数据发送出;接收数据时,将其存入接收缓冲区,并标识数据供上层模块处理。

The ARINC429 bus is based on CPLD and HS-3282. The HS-3382 consists of 2 receivers and 1 transporter. The interface logic between HS-3282and 8-bit MCU was realized in single CPLD. When data was sent by system, the data was stored in send buffer at first; and then it was sent through communication module. When the data was received, the data was stored in receive buffer at first, then the data was marked and managed by the upper module.
