Im totally new with these and totally lost, help me please.
Also beware that the model I quoted runs at 3.3V, so you either have to modify your arduino to run at 3.3/3.6V or make a voltage divider for the data pins.
Since it still took me a while to get it working with this library, please note the following:
The jumper for 3.3v/5v only applies to VCC and the backlight. The input/outputs always have to be 3.3v. The jumper does not apply to the logic pins.
You can use the screen by only connected the pins on the "yellow pin header":
RST -> RST (3.3v)
CE -> CS/SS (3.3v)
D/C -> DC (3.3v)
DIN -> MOSI (3.3v)
CLK -> SCLK (3.3v)
VCC -> VCC (3.3v or 5v, see jumper on back side)
BL -> BL (3.3v or 5v, see jumper on back side)
GND -> GND
Note that the soldable sockets can be used as well, but this configuration is easier/quicker to use.
You can use 2 TFTs (or more) on the SPI pins by only using different CS, DC and RST pins. So instead of 5*2 = 10 pins, you'll be needing 5+3 = 8 pins.

Thanks Ragoune! For me this was the solution, I needed the connections for the yellow connector, works great!
Just one question: I do not quite understand how to connect two displays, what do I have to connect and how to program them?
BTW I am using UTFT library..
Hi everyone,
I've tryed without succes to adapt those S6D02A1 library to ATMEL STUDIO without succes.
I now work on ARDUINO and load the sketch in my standalone chip.
I have a problem makikng this screen work.
Each example i load into my arduino UNO gives me the same result :
I get colored lines on the screen !! (See attachement)
Does anyone obtain the same issue ?
I checked my wiring twice and it's the same with two different units.
I cabled all the lines with 1.3Kohm resistors and the BL is cabled with 47Ohm on VCC (5v)
CLK -> 13
DIN -> 11
D/C -> 8
C/S -> 9
RST -> 7
The User_Setup.h is also set with those pins.
I tryed 2 differents libraries (TFT_S6D02A1 and Adafruit_QDTech-master) with the same issue.
