QRcodeOled

Subclass that you can use jointly with https://github.com/yoprogramo/QRcodeDisplay to generate QRcodes in OLED displays like SSD1306 and SSH1106

To use it:

In platform.io:

add as dependencies:

yoprogramo/QRcodeDisplay
yoprogramo/QRcodeOled
thingpulse/ESP8266 and ESP32 OLED driver for SSD1306 displays

In arduino ide:

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

 QRcodeDisplay
 QRcodeOled
 ESP8266 and ESP32 OLED driver for SSD1306 displays

Creating a QRcode is just as simple as:

#include <qrcodeoled.h>
#include <SSD1306.h>

SSD1306  display(0x3c, 21, 22); // Only change
QRcodeOled qrcode (&display);

void setup() {

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

}
