Embedded Order System Terminal Based On Linux

Along with the development of the technology of embedded system, the embedded platform combining the 32-bit RISC Processor of ARM Corporation with the free, source-open, well-performed Linux operating system , has been more and more favored by the embedded handset device manufacturers, and has recently displayed a significant market value and application prospect.This dissertation is about the design of a Linux-based embedded handset device of a food-ordering system terminal.ft first introduces the concept of embedded system, the merits of linux as the operating system for embedded handset devices, and then discusses the characteristics of an embedded linux handset device platform in developing a food-ordering system terminal.A handware platform is designed and a software development platform is established. The hardware platform consists mainly of three major modules: a core module with s3c2410 as the processor, a wireless correspondence module based on RF 905, and a LCD touching screen module based on LQ035Q7DB02. LZ9FC22 and ADS7846.Then, a Iinux-based wireless correspondence module is designed and a MiniGUI development platform is established on the PC machine and the embedded system. The engine mechanism of IAL and GAL of MiniGUI and the source codes for the translplantation of it are analyzed and MiniGUI is transplanted to establish the Linux-based embedded handset device.Finally, a food-ordering system software is designed on the basis of need analysis of the restaurant, food-ordering terminal system. Using of the listening to wireless carrier wave and de designing of communication protocol, the wireless communication of many-to-one is realized.
