THIS REPO IS OBSOLETE, THE DEVELOPMENT CONTINUES IN:
https://github.com/yoprogramo/QRcodeDisplay
Please, take a look... This repo will not receive furhter updates.
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
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)
- Open Arduino IDE, try examples of ESP QRcode library
