Hi,

 

Is there a RGB565 LCD video driver alredy implemented? I think the ez extender LCD board (for BF526 ezkit) has such a display...

 

Regards,

Nikolay

Are you asking it in the uboot or the uClinux distribution?

 

In uboot I don't think there is a driver for the LCD EZ Extender on the BF526 ezkit.

 

In the uclinux the frame buffer driver is already available as  "linux-2.6.x/drivers/video/bfin-lq035q1-fb.c".

I'm asking for U-boot.

 

As there is no any hardware way to arrange RGB565 for BF52x PPI I'm asking if some body alredy has implemented this. It's not fancy, just few bit shifts, but if there is already written drive I'd like to use it instead of double work.

 

Regards,

 

Nikolay

the only drivers written for u-boot are the displays on the bf527-ezkit and bf548-ezkit, and they are pretty simple drivers

 

you'll have to write your own for your board.  just look at video.c in those board dirs.
