QRcode_ST7735

Subclass that you can use jointly with https://github.com/yoprogramo/QRcodeDisplay to generate QRcodes in TFT displays like ST7735

To use it:

In platform.io:

Add as dependencies:

• yoprogramo/QRcodeDisplay

• yoprogramo/QRcode_ST7735

• adafruit/Adafruit GFX Library

• adafruit/Adafruit ST7735 and ST7789 Library

  In arduino ide

  Open Library Manager (menu Sketch > Include Library > Manage Libraries…) then install the following libraries:

• QRcodeDisplay

• QRcode_ST7735

• Adafruit GFX Library

• adafruit/Adafruit ST7735 and ST7789 Library

  Creating a QRcode is just as simple as:

  
  #define TFT_RST   25    
  #define TFT_CS    5     
  #define TFT_DC    26    

include

include

include

include

define TFTMODEL INITR_144GREENTAB

Adafruit_ST7735 display = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_RST); QRcode_ST7735 qrcode (&display);

void setup() {

display.initR(TFTMODEL);
qrcode.init();
qrcode.create("Hello world.");

}
