Bonjour,
Je débute seulement dans le codage Arduino, je voulais tester ShowBMP.ino que je trouve bien sympathique.
tout c'est bien passer pour la vérification et le téléversement du code que je trouver sur le internet pour cette carte : https://www.amazon.fr/Elegoo-ATmega328P-ATMEGA16U2-Controller-Microcontrôleur/dp/B01N91PVIS/ref=asc_df_B01N91PVIS/?tag=googshopfr-21&linkCode=df0&hvadid=194956736627&hvpos=&hvnetw=g&hvrand=6397621278416650929&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9056015&hvtargid=pla-329356109727&psc=1&mcid=2193ae8f85b33dd3bc8948b351aabc81
Maintenant que que j'ai alimenté la carte, un problème de couleur sur l'écran TFT LCD Ecran Tactile 3,5 pouces: https://www.amazon.fr/Hilitand-Module-Tactile-Arduino-480x320/dp/B07HT6ZH7L/ref=sr_1_11?keywords=tft+lcd+module&qid=1701959576&sr=8-11
voici le code que j'ai actuellement :
// 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
#include <SD.h>
#include <SPI.h>
// 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 PIN_SD_CS 10 // Adafruit SD shields and modules: pin 10
#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
Adafruit_TFTLCD tft(LCD_CS, LCD_CD, LCD_WR, LCD_RD, LCD_RESET);
// If using the shield, all control and data lines are fixed, and
// a simpler declaration can optionally be used:
// Adafruit_TFTLCD tft;
