| The Embedded Development Platform of Data Terminal is designed on basis of demand analysis for JiangSu Elefirst Technology Limited Company in order to offer a second development platform which is used to design data terminal products. The thesis mainly introduces the design and development of software part of this platform.On the basis of demand analysis of embedded data terminal products and the research on variety of microprocessors and embedded operate systems, this platform is designed based on LPC2292 microprocessor and μC/OS- Ⅱ . μC/OS- Ⅱ is transplanted to LPC2292 microprocessor, then the transplanted code is tested. The external equipment drivers, which will help the programmer to design user program of products during the second development, are designed and developed, such as memory module, communication module, man-machine interface module. The platform is debugged successfully and the external equipment drivers are proved right.The test results of The Embedded Development Platform of Data Terminal show that the system has met the function demand and realized the anticipative goal. |
