摘要
ARINC429规范是现代航空电子设备数字传输的一种标准,与计算机之间的通信受到航空业的重视;详细介绍了在Visual C++6.0环境下,利用控件实现ARINC429标准数据通过计算机串口发送和接收的方法,给出了TI公司的TMS320F2812型DSP和MAX232型收发器的硬件接口电路,以及在此基础上使用中断和查询方法实现PC串口的初始化、发送和接收数据程序代码,同时给出DSP SCI的软件流程;并通过具体应用证明了可靠性和稳定性。
ARINC Specification 429 is a digital data transfer standard of aeronautical electronic devices in modern times, more attentions are paid to data communication with computer by aviation industry. The hardware circuit of interface of TMS320F2812 and MAX232 are designed, besides , the initialization, transmission and receiving procedure code of PC serial communication port based on interruptive and inquiring method is also designed. Finally, software flow diagram of SCI of DSP is provided, Through the specific application, it proved that the system was reliability and stability.
