ESP QRcode

Just copy the ESP QRcode folder to your Arduino 'libraries' folder. I have included an example sketch.

The code is based on qrdquino by tz1 : https://github.com/tz1/qrduino

This code is a fork of https://github.com/anunpanya/ESP8266_QRcode

Install dependency for ESP8266 QRcode

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

• ESP8266 Oled Driver for SSD1306 display by Daniel Eichborn, Fabrice Weinberg

For TFT:

• Adafruit GFX
• Adafruit ST7735 (or ST7789)

For eink display:

• Adafruit GFX
• https://github.com/lewisxhe/GxEPD

Depending on the display you want to support you have to uncomment the corresponding define in qrcode.h (or keep all commented an define it in your own code)

Run examples from ESP8266 QRcode

• Open Arduino IDE, try examples of ESP QRcode library
