| Abstract: | This paper introduces a general method to form a LCD circuit based on the platform of ARM9 S3C2410,and how to take advantage of Framebuffer for LCD drivers under Embedded Linux.It describes how the Framebuffer works and the related usage of the lower level drivers.Various functions are provided by systerm which supplies the hardware and software basis for deeper development. |
