Bonjour,

Je suis actuellement en train de débuter l'apprentissage d'Arduino avec un écran tactile (https://www.amazon.fr/Kuman-Tactile-Arduino-Module-Fonction/dp/B075CXXL1M/ref=sr_1_4?__mk_fr_FR=%C3%85M%C3%85%C5%BD%C3%95%C3%91&crid=1I93HCO6UURF3&keywords=%C3%A9cran+tactile+arduino&qid=1579090276&sprefix=%C3%A9cran+tactile+a%2Caps%2C169&sr=8-4)

Maintenant je souhaiterais afficher un texte sur cet écran et j'ai justement un code mais je ne le comprends pas.

Pourriez-vous m'expliquer le code et me dire si je peux enlever une (ou des) partie(s) inutiles.

Voici mon code :

// IMPORTANT: Adafruit_TFTLCD LIBRARY MUST BE SPECIFICALLY
// CONFIGURED FOR EITHER THE TFT SHIELD OR THE BREAKOUT BOARD.
// SEE RELEVANT COMMENTS IN Adafruit_TFTLCD.h FOR SETUP.
//Technical support:goodtft@163.com

#include <Adafruit_GFX.h>    // Core graphics library
#include <Adafruit_TFTLCD.h> // Hardware-specific library

// The control pins for the LCD can be assigned to any digital or
// analog pins...but we'll use the analog pins as this allows us to
// double up the pins with the touch screen (see the TFT paint example).
#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

// When using the BREAKOUT BOARD only, use these 8 data lines to the LCD:
// For the Arduino Uno, Duemilanove, Diecimila, etc.:
//   D0 connects to digital pin 8  (Notice these are
//   D1 connects to digital pin 9   NOT in order!)
//   D2 connects to digital pin 2
//   D3 connects to digital pin 3
//   D4 connects to digital pin 4
//   D5 connects to digital pin 5
//   D6 connects to digital pin 6
//   D7 connects to digital pin 7
// For the Arduino Mega, use digital pins 22 through 29
// (on the 2-row header at the end of the board).

// Assign human-readable names to some common 16-bit color values:
#define	BLACK   0x0000
#define	BLUE    0x001F
#define	RED     0xF800
#define	GREEN   0x07E0
#define CYAN    0x07FF
#define MAGENTA 0xF81F
#define YELLOW  0xFFE0
#define WHITE   0xFFFF

#include <MCUFRIEND_kbv.h>
MCUFRIEND_kbv tft;
// If using the shield, all control and data lines are fixed, and
// a simpler declaration can optionally be used:
// Adafruit_TFTLCD tft;

void setup(void) {
  Serial.begin(9600);
  Serial.println(F("TFT LCD test"));

  tft.reset();

  uint16_t identifier = tft.readID();
  if(identifier == 0x9325) {
    Serial.println(F("Found ILI9325 LCD driver"));
  } else if(identifier == 0x9328) {
    Serial.println(F("Found ILI9328 LCD driver"));
  } else if(identifier == 0x4535) {
    Serial.println(F("Found LGDP4535 LCD driver"));
  }else if(identifier == 0x7575) {
    Serial.println(F("Found HX8347G LCD driver"));
  } else if(identifier == 0x9341) {
    Serial.println(F("Found ILI9341 LCD driver"));
  }else if(identifier == 0x7783) {
    Serial.println(F("Found ST7781 LCD driver"));
  }else if(identifier == 0x8230) {
    Serial.println(F("Found UC8230 LCD driver"));  
  }
  else if(identifier == 0x8357) {
    Serial.println(F("Found HX8357D LCD driver"));
  } else if(identifier==0x0101)
  {     
      identifier=0x9341;
       Serial.println(F("Found 0x9341 LCD driver"));
  }else if(identifier==0x9481)
  {     
       Serial.println(F("Found 0x9481 LCD driver"));
  }
  else if(identifier==0x9486)
  {     
       Serial.println(F("Found 0x9486 LCD driver"));
  }
  else {
    Serial.print(F("Unknown LCD driver chip: "));
    Serial.println(identifier, HEX);
    Serial.println(F("If using the Adafruit 2.8\" TFT Arduino shield, the line:"));
    Serial.println(F("  #define USE_ADAFRUIT_SHIELD_PINOUT"));
    Serial.println(F("should appear in the library header (Adafruit_TFT.h)."));
    Serial.println(F("If using the breakout board, it should NOT be #defined!"));
    Serial.println(F("Also if using the breakout, double-check that all wiring"));
    Serial.println(F("matches the tutorial."));
    identifier=0x9486;
    
  }
  
  tft.begin(identifier);
  Serial.print("TFT size is "); Serial.print(tft.width()); Serial.print("x"); Serial.println(tft.height());

}

void loop(void) {
   tft.fillScreen(BLACK);
  unsigned long start = micros();
  tft.setCursor(0, 0);
  
  tft.setTextColor(GREEN); tft.setTextSize(2);
  tft.println("Hello World!");
  
  delay(1000);delay(1000);delay(1000);delay(1000);delay(1000);
}

Merci pour votre aide

Cordialement
