Connect ESP8266 to a TFT display via SPI

[Santaionut]

Hi,

I have next problem, I want to connect a display to ESP8266 via SPI . The display not have CS pin have only next pins GND, VCC, CLK, MOSI, RES, DC, BLK, MISO. The driver for this display is ILI9341.

I tried next things:

1. I changed the next lines in User_Setup.h
   `#define TFT_SPI_OVERLAP

#define TFT_MISO 12
#define TFT_MOSI 13
#define TFT_SCLK 14`

2. I connected the display to ESP

ESP => TFT
GPIO12 -- MISO
GPIO13 -- MOSI
GPIO14 -- CLK
3v -- VCC
GND -- GND

3. I uploaded on ESP next code

`#include <TFT_eSPI.h> // Graphics and font library for ILI9341 driver chip
#include <SPI.h>

#define TFT_GREY 0x5AEB // New colour

TFT_eSPI tft = TFT_eSPI(); // Invoke library

void setup(void) {
Serial.begin(9600);
tft.init();
tft.setRotation(2);
}

void loop() {

// Fill screen with grey so we can see the effect of printing with and without
// a background colour defined
tft.fillScreen(TFT_GREY);
Serial.println("Test ......");
// Set "cursor" at top left corner of display (0,0) and select font 2
// (cursor will move to next line automatically during printing with 'tft.println'
// or stay on the line is there is room for the text with tft.print)
tft.setCursor(0, 0, 2);
// Set the font colour to be white with a black background, set text size multiplier to 1
tft.setTextColor(TFT_WHITE,TFT_BLACK); tft.setTextSize(1);
// We can now plot text on screen using the "print" class
tft.println("Hello World!");

delay(10000);
}`

And after upload the display not show anything.

can you help me with this problem ?

Thanks!

These are the recommended connections:
https://github.com/Bodmer/TFT_eSPI/blob/master/User_Setup.h#L139-L147

If you use these with an unchanged copy of TFT_eSPI then it should work fine.

Here are the GPIO to PIN_Dxx corresponing signals if your anre not using a NodeMCU board.:

Thanks, I'll try and let you know if works well!
