HI i've bought this screen but do't find good parameters to do it work fine.

 Not working.
I dont know how to.
Can you help me?

LCD Work in parallel rgb 8 BITS.
I will offer you money if it works!!

Thanx

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_if: lcd interface:

lcd_interface

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

I Choose 8080
Your qurstion or not?

I want the most simple
RGB 8 bits is set per defult in my lcd

I mean, what value did you set on IMx pins on LCD ;)

Anything because I can not do it

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.

OK thanx dave-at-axon
i don't know if you are right

which cheap lcd in range 2.4"  3.2"  choosen?


Thanx

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.
