QuecPython + camera: Implement QR Code/Barcode Scanning and Photo Capture

Overview

With a QuecPython development board paired with a camera module, developers can easily implement code scanning (QR code/barcode recognition) and photo capture functions, which are applicable to scenarios such as smart access control, industrial inspection, and mobile payment.

Core Features

Minimalist Development Experience: No need to write underlying drivers, complete photo capture with just 3 lines of code.

Plug and Play: Supports common camera modules (such as GC032A).

Cross-platform Compatibility: Code can be ported to other QuecPython development boards that support camera functions.

Working Mode

Note: The LCD must be initialized before using the camera function.

For the LCD initialization program, please refer to: https://github.com/QuecPython/QuecPython_lib_bundles/tree/master/libraries/LCD
