I'm at the stage where I'd like to start testing the screen. Does anyone have a scrfeenshot of their directory structure. I've never loaded anything to an arduino before

I have both the 4.3 and 5 inch displays working without the shield using the examples and libraries provided by the vendors.

here's the 5" instructions below. The 4.3 is a bit more involved. Buy the shield from sainsmart. They don't bundle it anymore and will tell you it does not work. It does!

4.3" instructions:

On the shield there are jumpers. You must remove the shorts for 5V and apply the shorts for 3.3V

To run a test what you need is here, just follow similaar steps in the 5" instructions:
101-50-150 - [[:Template:SainSmart Wiki]]


5" instructions:

I got the no touch test pattern on the 5" display to work.

For those that are new (myself included), here's what I did.

Download the example file from buydisplay.com.

Extract it and the copy the UTFT folder located in Libraries-Examples_ER-TFTM050-4\Libraries into the Libraries folder in the Arduino folder under My Documents (Windows).

Open the .ino file located here Libraries-Examples_ER-TFTM050-4\Examples\No_Touch_GraphicTest

compile and upload the code

Remove the usb cable from the programming port

Assemble the shield, screen, and arduino together

Plug a 7-12 Vdc 1A or more power source into the power socket on the arduino board

It should display the test

From the pictures of the working setup it appears you only need the following parts

C2 100n 1206
C3 100n 1206
C4 100n 1206
C10 100n 1206
R1 8.2K 1206
R2 2K 1206 pull-up resistor (optional)
R3 2K 1206 pull-up resistor (optional)
Q1 BC807, BC808 or other equivalent PNP SOT-23 TFT backlight control
U1 24LC256 SO-08 EEPROM chip
U2 Si8605 SOIC-16 I2C Isolator

I will install them tomorrow and then try to get the software working for the 4.3" display first
