基于LPC1758的COM-E主板接口扩展设计

Interface Design of COM-Express Module Based on LPC1758

采用ARM处理器LPC1758作为核心,完成了一种基于COM-E主板LPC总线的高实时性多串口接口电路设计,给出了关键电路原理图和串口实时处理程序。项目实际应用表明,系统电路设计及编程简便易行,实现了实时的姿态仪信息接收、处理。

With ARM processor LPC1758 as the core, this study completed a muhi-serial port interface de- sign of high real-time requirements based on LPC bus, and gave the critical circuit schematics and the re- al-timing process. The projects application validated that the circuit and programming of this design is sim- ple and easy to be realized. The design achieved a real-time information receiving and processing program of an Attitude Heading Reference System.
