| 摘 要： | 介绍了在嵌入式linux系统下利用帧缓冲控制显示芯片的方法，并以SW565R显示芯片为例进行了分析。帧缓冲是出现在linux2．2．xx内核中的一种驱动程序接口，它将显示设备抽象为帧缓冲区，通过帧缓冲区可以对显示内存进行读写，写的结果则反应在屏幕上。结果证明这种驱动显示芯片的方法能高效地应用在嵌入式系统中。

| Abstract: | This paper proposes the solution using framebuffer to control display device,in embedded linux and analyzes the example of display device ST7565R.A Framebuffer is a device interface in the linux 2.2.xx kernel.This interface abstracts the display device as framebuffer through which display memory can be read or written and the writing results can be displayed on the screen.The results show that the solution could be used in the embedded system effectively. |
