TFT_eSPI::fillScreen

Description

Clear the screen to defined colour.

Signature

void TFT_eSPI::fillScreen(uint32_t color)

Parameters

uint32_t color: Desired color.

Result

None.

Example

Example 1:

#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.

Note

You need to modify the User_Setup_Select.h file to configure the TFT_eSPI library for your specific TFT display. Additionally, you may need to adjust the pin connections and the TFT_eSPI constructor to match your hardware setup.

Example 2:

#include <TFT_eSPI.h>

TFT_eSPI tft = TFT_eSPI();

void setup() {
  tft.init();
  tft.setRotation(1);
  tft.fillScreen(TFT_BLACK); // Fill the screen with black
}

void loop() {
  // Your code here
}

In this example, the fillScreen function is used to fill the entire screen with a black color (defined as TFT_BLACK) after initializing the TFT display and setting its rotation to 1.
