Display Fundamentals

Initializing and configuring the display

This is done first of all by defining an instance of TFT_eSPI:

TFT_eSPI tft = TFT_eSPI();

Then you have to setup the device:

void setup(void) {
    tft.begin();
    tft.setRotation(1); // Depending of the use-case.

Now you are ready to use your screen.

Basic drawing functions

void loop() {
  tft.setTextSize(1);           // No size multiplier
  tft.fillScreen(TFT_BLACK);    // Fill the screen with back colour
  tft.setTextColor(TFT_GREEN, TFT_BLACK);   // Set text color to green and padding to back

  tft.drawString(" !\"#$%&'()*+,-./0123456", 0, 0, 2);  // draw top left
  tft.drawString("789:;<=>?@ABCDEFGHIJKL", 0, 16, 2);
  tft.drawString("MNOPQRSTUVWXYZ[\\]^_`", 0, 32, 2);
  tft.drawString("abcdefghijklmnopqrstuvw", 0, 48, 2);

  delay(1000);
}

Has been herited from Print, you can also use all versions of print() function:

void loop() {
  const auto some_value = 12.3;
  tft.setTextSize(1);           // No size multiplier
  tft.fillScreen(TFT_BLACK);    // Fill the screen with back colour
  tft.setTextColor(TFT_GREEN, TFT_BLACK);   // Set text color to green and padding to back
  tft.setCursor(0,15);
  tft.print("Some text = ");
  tft.println(some_value);
  delay(2000);
}
