Title Development of Touch Screen Driver Based on SEP3203 and uClinux
Abstract
With the development of computer technology and electronic technology,
embedded system has become a major pillar of the information industry, and
has broad prospects. uClinux system, as a derivative system of the Linux
system, is widely accepted because of its stable performance, its flexible
development environment and the completely open source code. Linux
transplantation and its device driver development have always been the
focus of the embedded system. This paper details the current development
of embedded systems and SEP3203 processor, as well as the corresponding
software and hardware development environment. Furthermore, this paper
states a detailed study of the virtual machine-based Linux installation,
the modification of uClinux system modules and transplantation to the board
based on ARM chip. When system transplantation is completed, uClinux touch
screen driver on ARM board was realized following the Linux device driver
development standards.

1 绪论
在信息技术飞速发展的今天，技术和产品的革命日新月异。每一次硬件系统的升
级都伴随着软件领域的一场变革。嵌入式系统，作为近几年一个新兴的产业，正引领
着电子信息产业的发展。
嵌入式系统领域不同于以往几家公司独大的状况，而是各个公司甚至个人都可能
开发出适合市场的软件。而在该领域内，Linux 操作系统因为其源代码完全开放、运
行稳定、架构清晰、修改灵活而成为嵌入式领域的一颗超新星。人们熟悉的安卓手机
正是 Linux移植的典范。
而光有一个稳定的系统是远远不够的，各个设备的协调运转才是整个设备的关键。
因此，设备的驱动程序作为硬件和软件的桥梁，发挥着决定性的作用。
