用于S3C44B0X液晶屏的uclinux驱动设计

The Design of Uclinux Drivers For S3C44B0X

分析了LINUX2.4下Framebuffer驱动程序的框架和各个相关文件之间的相互引用关系,并用图形的方法给出了驱动程序本身的函数流程。介绍了开发一个Framebuffer驱动程序的步骤,分析了Framebuffer用户接口和系统调用的关系。然后针对S3C44B0X和SHARP STN液晶屏给出了一个自己编写的完整Framebuffer驱动程序,并对源代码做出了详细的分析。

First,the structure of source codes and the ralationship of referred files about the Framebuffer in Linux 2.4 are analyzed,we also provide the process of the functions in the way of graphics.Then you would like to see the program designing a Framebuffer device drivers. The relationship of user interface and system call is also analyzed. Finally,based on the platform of S3C44BOX and SHARP STN LCD,we have designed our own Framebuffer device driver while these source codes are analyzed in detail.
