# QR Code generator component
This directory contains a QR code generator component written in C. This component is based on [QR-Code-generator](https://github.com/nayuki/QR-Code-generator).
This component is used as part of the following ESP-IDF examples:
- [DPP Enrollee Example](../../wifi/wifi_easy_connect/dpp-enrollee/).
To learn more about how to use this component, please check API Documentation from header file [qrcode.h](./include/qrcode.h).
Please note that this component is not considered to be a part of ESP-IDF stable API. It may change and may be removed in the future releases.
