QR USB HID Keyboard
●This application note is written to introduce a general approach to implementing QR Decode application on AT32 MCUs, and upload the decoded data to PC through USB HID keyboard.
■Overview:
●Nowadays, barcode technology has been widely used in our daily life, such as WeChat QR code, Ali Pay barcode, commodity barcode and supermarket locker barcode. Due to the complexity of two-dimensional code, it is necessary to optimize barcode recognition equipment.
●In this application note, the AT32F403A MCU featured with FPU, large-size SRAM and high frequency is used together with Artery_QR code decoding library to scan and recognize two-dimensional code and CODE128\CODE39\I25\EAN13 barcode on AT-START-F403A evaluation board.
