9g15-ek and Custom LCD

Mon Dec 24, 2012 2:48 pm

Hi community.

I'm using SAM9g15-ek board and Android 2.3.7 BSP. AS you know, kit has 5" 800x480 LCD.
And i added some modifications to "board-sam9x5ek.c" file.(like xres, yres, pixclock) And i was able to use another LCD(4.3" 480x272), properly. It worked!
But just for one model. I purchased some samples from different manufacturers. But just one LCD is working. All are pin compatible, also they have same pins.(RGB 0..8, HSYNC, VSYNC, PCLK etc.)

Now i noticed that; there is a controller on LCD. Brand is depend on manufacturer. Also some LCD has no any controller. But both of them have same pin names. There is no controller specific line.

Dou you know any tip or any link to give some information to me. What i must do?

But are the signal requirements the same?

You'll need to refer to the technical documentation for the panels to understand the configuration and timing requirements.
