I am trying to use a 3.2 inch Touch TFT Display on a Mega 2560. I have purchased a Shield from Amazon which states it is for a mega. The display is a ILI9341 3.2 inch TFT Display Module LCD Screen 320x240 Resistive Touch Panel. I have spent hours trying different tutorials and different sketch"s, but all I get is a white screen. I believe I am using the correct libraries so something else is not right. I suspect it may be that the shield is not correct as have been stated in other conversations. I don"t know how to determine if it is the correct on one for that display. When I look at other shields they do not seem to give enough information regarding the pin-out. I guess my question is how to determine which one is correct? I am fairly new but have developed other Arduino sketches" but nothing this complicated. Can anyone clue me in on how to take care of this problem?
Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (5" diagonal) bright (12 white-LED backlight) and colorful 480x272 pixels with individual pixel control. As a bonus, this display has a capacitive touch panel attached on screen by default.
The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you"ll have it running in under 10 minutes! Works best with any classic Arduino Mega 2560.
This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. You can connect more sensors, buttons and LEDs.
Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library at the bottom of this page that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x,y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!
If you"ve had a lot of Arduino DUEs go through your hands (or if you are just unlucky), chances are you’ve come across at least one that does not start-up properly.The symptom is simple: you power up the Arduino but it doesn’t appear to “boot”. Your code simply doesn"t start running.You might have noticed that resetting the board (by pressing the reset button) causes the board to start-up normally.The fix is simple,here is the solution.
