Linux driver for LIDD interface for Graphics LCD

Dipen,

     Are you aware of the Linux Software Developers Kit for the AM1x parts? You might want to dig around in there to see if there is a driver you are looking for.

HI Drew Abuan,

Yes I have looked into Linux SDK that is part of DVSDK v4####. 

The driver available at location psp/linux-2.6.33-rc4-psp03.20.00.14/drivers/video/da8xx-fb.c is frame buffer driver for Raster controller. 

There is another driver at location psp/linux-2.6.33-rc4-psp03.20.00.14/drivers/staging/panel/parport-da8xx.c. This seems to be for character LCD though it is LIDD i/f.

I am looking for any reference driver that is using LIDD interface for Graphical LCD. Or let me know what changes are required to make above driver to work with Graphical LCD.

Regards,

Dipen Patel

Dipen,

   I'm not aware of any canned drivers that are ready to use. You may want to check out the OMAP-L137 Linux LCD Driver Wiki for an overview of the driver so see what you need to change.

I just made one for LIDD, but TI's document is not clear enough, you must guess...

for LIDD, 16bit is suggested or you must do the timing by your own program. we use VFB and make a timer to re-organize the data to the real FB by a timer trigger event in a 8bit lcm.
