qrcode()

Description:

Creates a QR code.

Function Prototypes:

void qrcode(const char *string, uint16_t x, uint16_t y, uint8_t width, uint8_t version);

void qrcode(const String &string, uint16_t x, uint16_t y, uint8_t width, uint8_t version);

 | uint8_t          | Width (pixels)         |

| version | uint8_t | QR code version |

Example Usage:

#include <M5Core2.h>

void setup() {
  M5.Lcd.begin();   //Initialize M5Core2
  M5.Lcd.qrcode("http://www.m5stack.com", 50, 10, 220, 6);
}

void loop() {

setColorDepth()

Description:

Sets the color depth.

Syntax:

Example Usage:

#include <M5Core2.h>
TFT_eSprite img = TFT_eSprite(&M5.Lcd);

void setup() {
    img.setColorDepth(8); // Set color depth.  Set the color depth
    img.setTextSize(2);
    img.createSprite(320, 240);  //Create a 320x240 canvas. Create a 320x240 canvas
}

void loop() {}

createSprite()

Description:

Creates a canvas of specified width and height.

Syntax:

TFT_eSprite img = TFT_eSprite(&M5.Lcd);

void setup() {
  M5.begin();  //Initialize M5Core2
  img.createSprite(320, 240);   //Create a 320x240 canvas
  img.fillSprite(RED);  //Fill the canvas with red
  img.pushSprite(0, 0, WHITE);  //Push the canvas to screen at (0,0) with white as the transparent color
  M5.Lcd.print(img.height());   //Print the height of the canvas on screen
}

void loop() {}

fillSprite()

Description:

void setup() {
  M5.begin();  //Initialize M5Core2
  img.createSprite(320, 240);   //Create a 320x240 canvas
  img.fillSprite(RED);  //Fill the canvas with red
  img.pushSprite(0, 0); //Push the canvas to screen at (0,0)
}

void loop() {}

pushSprite()

Description:

TFT_eSprite img = TFT_eSprite(&M5.Lcd);

void setup() {
  M5.begin();  //Initialize M5Core2
  img.createSprite(320, 240);   //Create a 320x240 canvas
  img.fillSprite(RED);  //Fill the canvas with red
  img.fillCircle(100,100,20,GREEN);
  img.pushSprite(0, 0, GREEN);  //Push the canvas to screen at (0,0) with green as the transparent color
}

void loop() {}

height()

Description:

  img.fill

Sprite(RED);  //Fill the canvas with red
  img.pushSprite(0, 0, WHITE);  //Push the canvas to screen at (0,0) with white as the transparent color
  M5.Lcd.print(img.height());   //Print the canvas height on screen
}

void loop() {}

deleteSprite()

Description:

Deletes the canvas from memory.

Syntax:
