« on: November 01, 2014, 01:42:45 AM »
HI i've bought this screen but do't find good parameters to do it work fine.

Maybe you could show some connection schematic between board and LCD?

Problem could be everywhere.

Ok,

1. I think that CS is not the same as LCD_VSYNC
2. You should try to pullup RST to get allways 1, and connect back light to stable voltage (not PWM), and then you could remove those two things from list, and we can go on.
3. Which MCU interface you set?

This?

lcd_interface

0 hv (sync + de)
1 8080
2 ttl
3 lvds

I Choose 8080
Your qurstion or not?

I want the most simple

Did you have schematic of those LCD board or pinout? Because on this page I can't see pinout.

Number one. It won't work with the LCD interface on the A10 without a driver. Even though the 8080 is supported in the LCD settings, it requires a driver to work and is not autonomous. I doubt the sunxi drivers are ready for this.

That LCD has a data bus connection and is designed to connect to a 16 bit bus and uses READ and WRITE to control the internal IL9325 controller which then handles the LCD driving. The CS is chip select and not sync.

Have a look at page 407 of the A10 datasheet. It shows that you need to read and write a register to send and receive data from the LCD.

http://dl.linux-sunxi.org/A10/A10%20User%20Manual%20-%20v1.20%20%282012-04-09%2c%20DECRYPTED%29.pdf

I think you are better off using an LCD with a native RGB interface as these work without any special drivers under Android and Linux.

They are not cheap but the Newhaven 3.5" is very nice and is 24 bit RGB so will work once you work out the timing.

They even have a new capacitive touch option too.
