QRcode_eSPI

Subclass that you can use jointly with https://github.com/yoprogramo/QRcodeDisplay to generate QRcodes in TFT displays like ST7735 and any other supported by TFT_eSPI

To use it:

In platform.io:

Add as dependencies:

• yoprogramo/QRcodeDisplay
• yoprogramo/QRcode_eSPI
• bodmer/TFT_eSPI

You can configure in platformio.ini the data about hardware model and connections

In arduino ide

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

• QRcodeDisplay
• QRcode_eSPI
• TFT_eSPI

Create or update your user_setup to match your hardware specifications.

Creating a QRcode is just as simple as:

#include <SPI.h>
#include <TFT_eSPI.h>
#include <qrcode_espi.h>

TFT_eSPI display = TFT_eSPI();
QRcode_eSPI qrcode (&display);


void setup() {

   display.begin();
   qrcode.init();
   qrcode.create("Hello world.");

}
