The Design And Research Of Photometer Based On ARM

The implement of photometer needs suitable hardware platform and intelligent control algorithms. And recently the embedded operation system has widely used in many fields, especially the uClinux. This paper is focused on this problem investigated.The design and application of embedded system for photometer,including the design of hardware platform, the uClinux transplanting and the drivers program, the thesis also studied control algorithms for photometer.First, The paper introduces the application actuality of ARM technology and embedded system, and reach a conclusion that embedded system constructed in photometer can greatly separate the design of hardware and software, and can realize the complex algorithms.Secondly, the paper focuses on the hardware design of embedded system for the photometer. The core of embedded system is base on ARM7TDMI processor-S3C44B0X In this part of the paper, the select of CPU processor, the select of memory and the design of peripheral equipment are recommended.Thirdly, based on the embedded hardware, the transplanting process the uClinux is introduced in particular, including mainly: the design of Boot Loader, the customization and compilation of Linux kernel, the choice of file system and the compilation of driver modules specially the driver module of the realization.Finally, This paper presents the design of application based on uClinux, including naturalization of minigui.
