Useful Commands When Using Adafruit Library
Rotate Display:
tft.setRotation(tft.getRotation()+1);
Fill Screen Black:
tft.fillScreen(ST77XX_BLACK);
Test wrapping on/off:
tft.setTextWrap(false);
Print Text/numbers various colors: tft.setCursor(0, 30); tft.setTextColor(ST77XX_RED); tft.setTextSize(1); tft.println("Hello World!"); tft.setTextColor(ST77XX_YELLOW); tft.setTextSize(2); tft.println("Hello World!"); tft.setTextColor(ST77XX_GREEN); tft.setTextSize(3); tft.println("Hello World!"); tft.setTextColor(ST77XX_BLUE);
Draw Lines:
tft.drawLine(tft.width()-1, 0, 0, y, color);
Invert Display colors:
tft.invertDisplay(true);
