Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (2.8" diagonal) bright (4 white-LED ...

The LCD is designed for use with an Arduino Uno. When I plug the sucker into my Mega I can"t get the "Arduino_TFT_Tutorial_Example_01" let alone the "graphicstest" codes to generate anything on the LCD. I believe I have all the recommended libraries for the LCD shield (although the recommendations assume I am using an Uno). All I get is the same lit up white screen before and after uploading.

I don"t have too much experience with the mega and I am not too crafty with the LCD yet so any info/suggestions are much appreciated. Not sure if this is an easy fix or a stretch.

Add some jazz & pizazz to your project with a color touchscreen LCD. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful! 240x320 pixels with ...

Thank you for your interest. I have now attempted to provide you with all the info that I have – including photos. The wiring shown in them is not very clear but I have listed under here all the Adafruit instructions I followed (many times) and guarantee that the wires connect what they should! The screen is folded back so that you can see the wires.

• CLK connects to SPI clock. On Arduino Uno/Duemilanove/328-based, thats Digital 13. On Mega"s, its Digital 52 and on Leonardo/Due its ICSP-3 (See SPI Connections for more details)

• MISO connects to SPI MISO. On Arduino Uno/Duemilanove/328-based, thats Digital 12. On Mega"s, its Digital 50 and on Leonardo/Due its ICSP-1 (See SPI Connections for more details)

• MOSI connects to SPI MOSI. On Arduino Uno/Duemilanove/328-based, thats Digital 11. On Mega"s, its Digital 51 and on Leonardo/Due its ICSP-4 (See SPI Connections for more details)

NOTE: Elsewhere is says that for the mega we should use Pin 53 but in graphicstest software it defines pin 10. To be safe I have tried both pin 10 and Pin 53 and modifying the define entry. Neither worked. Note also that the instructions refer to “SS” but we do not have a “SS” so I assume that this is “CS”. Further note – also connected are four touchscreen leads; I have tried it both with and without these connected. All above DONE! – thousands of times! Install Arduino Libraries. We have example code ready to go for use with these TFTs. It"s written for Arduino, which should be portable to any microcontroller by adapting the C++ source.

Three libraries need to be installed using the Arduino Library Manager…this is the preferred and modern way. From the Arduino “Sketch” menu, select “Include Library” then “Manage Libraries…”

Upload the graphicstest sketch to your Arduino. You may need to press the Reset button to reset the Arduino and TFT. You should see a collection of graphical tests draw out on the TFT.

If you"re having difficulties, check the serial console.The first thing the sketch does is read the driver configuration from the TFT, you should see the same numbers as below

If you did not connect up the MISO line to the TFT, you wont see the read configuation bytes so please make sure you connect up the MISO line for easy debugging! Once its all working, you can remove the MISO line

I have an Arduino Mega and a 2.8" Tft-Display-Shield from Adafruit. The Display is for the Arduino Uno, but the documentation says it can also be used with the Arduino Mega. Therefore it is needed to "solder three jumpers and you can use it at full speed on a Leonardo or Mega as well."
