    Скачал библиотеку с примерами для этого дисплея, все примеры работают, а когда сам пишу, то просто белый экран. Название библиотеки: MCUFRIEND_kbv - master. Подскажите в чём проблема. Ниже будут приложены, сначала пример, потом мой скетч.

    Мой скетч:
    Код (C++):
    #define LCD_CS A3 // Chip Select goes to Analog 3
    #define LCD_CD A2 // Command/Data goes to Analog 2
    #define LCD_WR A1 // LCD Write goes to Analog 1
    #define LCD_RD A0 // LCD Read goes to Analog 0
    #define LCD_RESET A4 // Can alternately just connect to Arduino's reset pin

    #include <SPI.h>          // f.k. for Arduino-1.5.2
    #include "Adafruit_GFX.h"// Hardware-specific library
    #include <MCUFRIEND_kbv.h>
    MCUFRIEND_kbv tft;

    #define    BLACK   0x0000
    #define    BLUE    0x001F
    #define    RED     0xF800
    #define    GREEN   0x07E0
    #define CYAN    0x07FF
    #define MAGENTA 0xF81F
    #define YELLOW  0xFFE0
    #define WHITE   0xFFFF

    #ifndef min
    #define min(a, b) (((a) < (b)) ? (a) : (b))
    #endif
    void setup(){
    }
    void loop(){
    tft.fillScreen(BLACK);
    delay(3000);
    tft.fillScreen(MAGENTA);
    delay(2000);
    tft.fillScreen(BLUE);
    delay(1000);
    tft.fillScreen(WHITE);
    delay(5000);
    }
    Ту часть кода, где описываются все функции я сократил в обоих кодах, т.к. недостаточно места.

    В setup добавьте:

    if (ID == 0xD3D3) ID = 0x9481; // write-only shield

    tft.begin(ID);
