Research And Development Of The Communications Interface On Windows CE.net+ARM9

At present, the intelligent protocol chip – ASPC2 to set up the PROFIBUS-DP master station areso often used. In consideration of the price of the project and the advantage of the embedded system, wechoose the PROFIBUS – DP protocol card, which is developed by ourselves. And we put it into theembedded system set by Windows CE.NET + ARM9. It is a totally new trial. Our embedded masterstation is based on the Microsoft Windows CE.NET operating system (OS) and the SAMSUNGS3C2410 mainboard. It communicates with its slave stations through the RS-485 serial port that is in theDP card.A brief introduction of the Embedded Intelligent Monitoring System, which is based on theembedded operation system of Windows CE.NET and ARM9, is provided .The practical application ofPROFIBUS-DP in this system is researched. The master station protocol chip, DP protocol card isdiscussed in details. The development of the software platform and the device driver of the DP protocolcard are presented.
