A transplantation method of QR code decoding program based on embedded platform was presented. The UP-NETARM2410-S was selected as the hardware development platform. Firstly, the system hardware composition was given. Then, the whole development process of QR code decoding program using Qt-Creator was introduced in detail. In the test phase, in order to simulate the running state of QR code decoding, the qvfb visual screen was used. Finally, the program was transplanted to true embedded platform. Test results showed that the decoding program can run normally on the embedded platform and correctly decode QR code information. The proposed transplantation method may have certain reference significance for different platforms QR code decoding.
