Hello,
I am trying 1 week. I bought the 2.8 TFT LCD touch DX site (Professional PVC Red LED Plate - White + Yellow (AC 110~220V) - Free shipping - DealExtreme)..
I am using a ILI9341, ILI9341-Adfruit lib but I did not succeed to run it. I tried different pin combinations in such a way
I tested anything goes wrong, I can not find the correct pins arduino uno r3
need some help with correct pin
You need to buy or make an adapter for your 34-pin 3.3V display to connect with your 5V Arduino.
Ready made 40-pin Adapter shields are very common. I don't think 34-pin Adapters are available.
You need about 24 5V to 3.3V level shifters. And obviously connect to the correct pins on the Arduino header sockets.

Try it with arduino due, this is the wiring:
Either way you must construct your own shield
Or leave the wires
what is the coding of the connection above?
may I have it?
thanks.

Hi TFTLCDCyg,
What kind of shield did you used?
I too, have one of these-and am quite unhappy with the Amazon seller who advertises them as "SPI-connect" and "ILI9341"
these are actually an SSD1289 controller, and have no option for SPI bus comms...they're parallel only, in 8 bit or 16 bit mode.
The touch controller and SD card slot are SPI, but not the display itself. Oh well.
Hi everybody..
at random somebody get to connect this display, 34 pin, in arduino uno??
I have one this too, like of Siberzeka and I it just appears a blank screen
Read #1 for a 5V Uno.
Read #2 for a 3.3V Due.
Seriously, it is more trouble than it is worth using a 5V Arduino.
You can always make your own Adapter with a Protoshield but it is quite a lot of work.
David.
hi i am also brought this one pls suggest library's and some sample codes
First off, you should say which 3.3V Arduino you are using.
#2 shows how to connect to a Due.
UTFT library should work out of the box.
I do not have this type 34-pin display. Is your one 2.8" or 3.2" ?
If you have connected to a Due, you can run the LCD_ID_readreg sketch.
Edit all the defines to match your wiring. Connect the RD pin to a regular Due pin.
MCUFRIEND_kbv library will work for your display if you use the appropriate SPECIAL wiring.
David.
Edit. Your other thread says 2.8" with a Mega2560.
So you just need about twenty four 5V to 3.3V level-shifters. And a lot of wires.
I hope that you enjoy the task. And that the effort is worthwhile.
Incidentally, I suspect that there is a solder-bridge option to select 8-bit mode. This would reduce the number of level shifters.

thanks.
did you get the code please!! send me it!!....
can you send me the wiring and the code please???
