Bonjour,
j'ai modifié un code pour obtenir ca :
#include <ST7735.h>
#include <Adafruit_GFX.h>
#include <Adafruit_ST7735.h>
#include <SD.h>
#include <SPI.h>
#define SD_CS 4 // Chip select line for SD card
#define TFT_CS 10 // Chip select line for TFT display
#define TFT_DC 8 // Data/command line for TFT
#define TFT_RST -1 // Reset line for TFT (or connect to +5V)
Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_RST);
#define BUTTON_NONE 0
#define BUTTON_DOWN 1
#define BUTTON_RIGHT 2
#define BUTTON_SELECT 3
#define BUTTON_UP 4
#define BUTTON_LEFT 5
#define BLACK 0x0000
#define BLUE 0x001F
#define RED 0xF800
#define GREEN 0x07E0
#define CYAN 0x07FF
#define MAGENTA 0xF81F
#define YELLOW 0xFFE0
#define WHITE 0xFFFF
int C=2;
void setup(void) {
Serial.begin(9600);
tft.initR(INITR_REDTAB); // initialize a ST7735R chip, red tab
// If your TFT's plastic wrap has a Green Tab, use the following:
//tft.initR(INITR_GREENTAB); // initialize a ST7735R chip, green tab
Serial.println("OK!");
tft.fillScreen(0x0000);
}
uint8_t readButton(void) {
float a = analogRead(3);
a *= 5.0;
a /= 1024.0;
Serial.print("Button read analog = ");
Serial.println(a);
if (a < 0.2) return BUTTON_DOWN;
if (a < 1.0) return BUTTON_RIGHT;
if (a < 1.5) return BUTTON_SELECT;
if (a < 2.0) return BUTTON_UP;
if (a < 3.2) return BUTTON_LEFT;
else return BUTTON_NONE;
}
uint8_t buttonhistory = 0;
void loop() {
uint8_t b = readButton();
tft.setTextSize(3);
if (b == BUTTON_DOWN)
{
tft.setTextColor(ST7735_RED);
tft.setCursor(0, 10);
tft.print("T Int = C");
buttonhistory |= 1;
}
if (b == BUTTON_LEFT) {
tft.setTextColor(ST7735_YELLOW);
tft.setCursor(0, 60);
tft.print("T Ext = C");
buttonhistory |= 2;
}
if (b == BUTTON_UP) {
tft.setTextColor(ST7735_GREEN);
tft.setCursor(0, 110);
tft.print("Niv Eau = D");
buttonhistory |= 4;
}
delay(100);
J'aimerai qu'a chaque mouvement du joystick, l'écran s'efface pour mettre le texte suivant
J'ai essayer de rajouter un tft.print (" "); mais ca ne marche pas
Une aide ?
Merci d'avance
