我将内核提供的linux-2.6.x\drivers\video\bfin-t350mcqb-fb.c

 

我写了一个TFT的驱动,运行测试程序的时候,色彩不对,并且图像靠左边偏,右边有一条黑屏。

 

请问可能是什么原因,如何修改?希望做过Lcd驱动的朋友能给点意见,谢谢。

 

我的驱动是在linux-2.6.x\drivers\video\bfin-t350mcqb-fb.c修改得到的。效果图片见附件(一个是我改的驱动效果图,另一个是不带系统驱动效果图)

 

I writed a tft drive ,when use the test program to test it , the colour is not right ,and the position of the image is not in the right place,it moves to the left side and left a blackbar on the right side .

 

I have attached the picture in the appendix.(the picture of 'drive_with_uclinux.JPG 'is test by  my drive ,the picture of 'drive_without_system.JPG' test by the drive without system which is a right drive )

 

Why it like this , and how to fix it ?

Hui,

 

What do you mean for "the driver without system"?

 

你说的“不带系统驱动效果图是什么意思”?
