My python beginner, write a program to realize now, can control the USB data acquisition sweep, namely every time a qr code through the scanning, can direct access to the data on the qr code, need a cycle

CodePudding user response:

The workings of a scanner and keyboard is the same, the result is a bar code and press enter,

1, make a window with TK wxpython or QT
2, add a text entry box,
3, do text box enter events, prompt the scanning barcode
