QR code
QR code generation with LVGL. Uses QR-Code-generator by nayuki.
Get started
- Download or clone this repository
- Download from GitHub
- Clone: git clone https://github.com/lvgl/lv_lib_qrcode.git
- Include the library:
#include "lv_lib_qrcode/lv_qrcode.h" - Test with the following code:
const char * data = "Hello world";
/*Create a 100x100 QR code*/
lv_obj_t * qr = lv_qrcode_create(lv_scr_act(), 100, lv_color_hex3(0x33f), lv_color_hex3(0xeef));
/*Set data*/
lv_qrcode_update(qr, data, strlen(data));
Notes
- QR codes with less data are smaller, but they scaled by an integer number to best fit to the given size.
