LCD display failure!

[407charles]

I'm trying to interface the arduino uno and the ILI9341 display but it's not working. It's frustrating that the only display I can work with it's the 20x4 liquid display. Here is the simple program to display a string but for some reason I can't make it work. I bought this display on Ebay. Is there a problem with it? Has anybody used it successfully? Can somebody help?

Hi 407charles,
Have you read all of this thread as there is a component update and sample flowcharts for ILI9341 gLCD.

Yes I already read it. the problem is that every time I want to download the new component it kick me out of the program saying that I can not open this project unless I got a valid project working, so I opened a project and tried again to down load without success. Also my display does not display at all. Only the back light works.

You don't open the gLCD_ILI9341.fcpx
found here
Did you place the component in:
C:\Program Files\Flowcode 6\components
If 32 bit windows
Or
C:\Program Files (x86)\Flowcode 6\components
If 64 bit windows?

I just did, it worked right!!! You were right, I probably damaged the one I was using because I did used it with 5V instead of 3.3 volts and that's why I give up for a while. Today I just did a voltage divider network using a 4.7 Kohm and a 2.2Kohm, and now I have a 3.3v logic signals (DATA, SCK, A, and CS). Finally, I connect the reset and VCC pins to the 3.3 volt arduino pin and the LED pin to the same 3.3v pin with a 1Kohm pulling resistor. thanks a lot.
