Embedded Data Terminal Platform Developed

With the increasing of availability of embedded system hardware and the lowering ofits price, and the expanding of application field, the importance of embedded file system isbecoming more and more significant.Embedded systems are usually diskless systems. In order to keep permanent data inthe systems, it is a widely adapted strategy to use flash memory. Therefore how to build aflash file system in embedded system is the focus of this thesis.The Embedded Development Platform of Data Terminal is a new intelligent meterreading platform which is designed for Jiangsu Elefirst Technology Company, based on thepurpose to solve some disadvantages of the existing meter reading system. The platform isbased on LPC2292 microprocessor andμC/OS-Ⅱoperating system. It also includes somemodules such as memory modules, communication modules and so on. On the basis of thedemand analysis of the products and the research of file system, combined with thecharacteristic of the design of embedded flash file system, an embedded NAND Flash filesystem based on FAT structure is built on the platform. At the same time thecommunication between Personal Computer and the terminal platform through UniversalSerial Bus is completed. Files can be transferred between the two.Through the debugging and testing of the system it is proved that the system reachesthe function and performance demand as expected, and achieves the anticipated target ofthe research.
