Tft display ILI9488 wiring to DUE

[adyhansolo]

Hi, I have a project where I want to connect a 3.5" tft display ILI9488 controller to a Due board. I'm a beginner and the first issue is how to connect (wire) the display to the board. And in accordance to this which would be the best library to work?
I'l try to post an image with my display.

Thanks for the answer, but as I said, I'm a beginner. You should tell me what to do with these lines of code. First: how to physically connect pin to pin?

[horace]

try Adafruit ILI9488 library

the SPI pins are on the header

Thanks. Ok, if I understand correctly, it is enough to connect the 4 SPI pins : CS, MOSI, MISO, SCK from display to the same pins on Due board. What about power pins: VCC and GND?
Should I connect to 3V3 and GND from DUE board?

I have a problem because I am using the same layout of card (4.0 display v1.1) and I am using the hardware SPI of the Due for the SD Card reader, and I need both the screen and the reader. I tried using these pins:

#define TFT_CS   A5    
#define TFT_CD   A3
#define TFT_RST  A4
#define TFT_LED  A0   
#define TFT_MOSI 51
#define TFT_MISO 50
#define TFT_SCK 52

but I get nothing but a blank white screen.

For my application I need the TFT plus the SD plus I have other peripherals (digipots, rotary controllers, and relays, near the limit of pins on the Due.

Tft 3.5 screen for Mega 2560 Rev3

Using a Mega 2560 Rev3. The ILI9486 screen I acquired from AliExpress — a shield — has no screen-off function. I need one since this will control an audio preamplifier and I want to have a standby function where the screen is dark but the IR remote and tap power button will both activate the preamp. So I need to know if anyone can point me to a color 3.5 inch Tft screen that will accept a screen off command and still has a SD card reader (i am storing data on it that I read for configuration). …

ILI9488 v1.1 red board and Arduino Due — white screen

I have a problem because I am using the ILI9488 (4.0 inch display v1.1). I am using the ILI9488 library from GitHub — GitHub - jaretburkett/ILI9488: Arduino Library for the ILI9488 TFT controller for 4 wire SPI. I have tried initializing with software SPI but all I get is a blank white screen and then the sketch hangs. I am using the hardware SPI of the Due for the SD Card reader, and I need both the screen and the reader. I tried using these pins: #define TFT_CS A5 #define TFT_CD A3…
