Abstract
Along with the rapid development of electronic technology, especially for the appearance of microcomputer with large scale integrated circuit, the research of modern technology has made a essential progress. The show up of embedded micro-controller technology has brought a newly technical revolution to the modern industrial control area. The most obvious advantage of a system built up with the embedded micro-controller is that it can be embedded into any micro or little scale device and equipment. This study introduces the implement of embedded FAT12 documental system onto the transformer integrated test system whose core is LPC2214, which makes this system capable of using documental format for test data storage. This study includes the mastery of the basic knowledge of FAT12 documental system in the embedded system, and part of the programs in C language. The functions of this program includes building a catalog, deleting a catalog, changing current catalog, converting user’s document/catalog name into system name, acquiring the beginning cluster number of specific catalog and other series of operations. The program covered in this dissertation is just a part of the documental system. The documental operation of embedded system can be realized combining with other part. This paper also presents the design of the related parts of software mentioned above.
