Description

Rotate the screen orientation m = 0-3 or 4-7 for BMP drawing.

Signature

void TFT_eSPI::setRotation(uint8_t m)

Parameters

int8_t m: direction [0-4] or [4-7].

The setRotation() function may accept a value between 0 and 3, where:

• 0: No rotation
• 1: Rotate 90 degrees clockwise
• 2: Rotate 180 degrees
• 3: Rotate 270 degrees clockwise

Result

None.

Example

#include <TFT_eSPI.h>

TFT_eSPI tft = TFT_eSPI();

void setup() {
  tft.init();
  tft.setRotation(1);
  tft.fillScreen(TFT_BLACK);
  tft.setCursor(0, 0);
  tft.setTextColor(TFT_WHITE);
  tft.setTextSize(2);
  tft.setTextFont(2); // Set the text font to font number 2
  tft.println("Hello World!");
}

void loop() {
  // nothing to do here, just display the "Hello World!" message
}

Let me explain what each line does:

• TFT_eSPI tft = TFT_eSPI(); creates an instance of the TFT_eSPI class, which is used to interact with the TFT display.
• tft.init() initializes the TFT display.
• tft.setRotation(1) sets the rotation of the display to 1, which means the display will be rotated 90 degrees clockwise.
• tft.fillScreen(TFT_BLACK) fills the entire screen with black color.
• tft.setCursor(0, 0) sets the cursor position to the top-left corner of the screen.
• tft.setTextColor(TFT_WHITE) sets the text color to white.
• tft.setTextSize(2) sets the text size to 2, which means the text will be displayed in a medium size.
• tft.setTextFont(2) sets the text font to font number 2, which determines the style and appearance of the text.
• tft.println("Hello World!") prints the "Hello World!" message to the screen.
