Topic: TFT display with 9341 controller (Read 105 times) previous topic - next topic

I am trying to get my new display going, but without success. The only thing i see is a white screen.
Hardware:
- Arduino Mega
- TFT Mega Shield V1.1 from Lseestudio.
- TFT screen type TFT_320QVT_9341.
I bought the display and shield as a package.
See the pictures attached.

From the type number it looks the controller type is ILI9341.

I am using UTFT and UTouch libraries from Henning Karlsen, downloaded recently, version 2.81.

In the sketch from howtomechantronics i included the line
UTFT myGLCD(ILI9341_S4P,38,39,40,41)
Also tried S5P instead of S4P.
Sketch compiles and uploads without problems.

I read a few things on this forum about changing UTFT library UTFT.h and UTFT.cpp, which may be required for this controller, but it is not fully clear to me what i should change.

I have built a few arduino projects, but never changed a library.

questions:
- how can i be sure i have ILI9341 controller? The controller cannot be seen on the display.
- By connecting it to the mega through the shield, does it use serial communication?
- any tips what i could try?

TFTLCDCyg has posted a modified UTFT library that supports your display.

Search for "TFT_320QVT_9341" in the box at the top right hand corner of your page.
