3.5" TFT LCD Display is not working with Arduino Mega 2560 R3

Question

Even I can't do similarly with my 2.4" TFT LCD in here still: 2.4" TFT LCD Shield isn't working on Arduino Mega

Now, I have bought 3.5" TFT LCD display for my Arduino Mega 2560 R3 to try whether I could run the screen or not, and it is not working now! I am so depressed and angry for these two's misbehaviors. I have already checked website and a lot of Arduino IDE code examples and libraries such as UTFT.h, UTouch.h, UTFT_MEGA, UTFT_CTE, TFTLCD. I tried these and I can not run my 3.5" screen. Where am I faulty? There is something below the screen shield: www.mcufriend.com and 3.5" TFTLCD for Arduino 2560. Are there any basic code or have anyone tried to run Mcufriend's displays correctly?

Download hennings new UTFT library.

in myGLCD define R61581 as this is the driver chip for 3.5 display.

Answer 2

Try this code:

https://www.dropbox.com/s/fce43rxofttl001/Librer%C3%ADas%20UTFT%20%2B%20UTouch%20para%203.5%20TFTLCD%20para%20Arduino%20Mega%202560%20%20-%20copia.rar

First delete the old UTFT library, then copy and paste the library inside de RAR file.

Answer 3

This might be a silly suggestion, but the mega2560 is 5v, and the display is 3.3v...and you need an interface board between. I have successfully run a 3.2" display using this interface board

Hope this helps

Answer 4

I have the same lcd shield from mcufriend. It has ILI9327 in 8 bit mode.

This shield doesn't work with original UTFT library (it supports only 16-bit mode).

Try modified version from https://github.com/dgolda/UTFT and use:

myGLCD(NIC35WS,38,39,40,41); //3.5" TFTLCD for arduino 2560 from mcufriend.com
