[Abstract]:The project is based on the "Shenzhen strategic emerging industry project", which is the cooperation between the teaching and research department and the Shenzhen municipal government of Guangdong province. The project is named as the key technology research and product development of the mobile communication and UHF radio frequency identification integrated terminal. This project is a part of the project, mainly through the study of the NFC protocol, After developing NFC applications for low end devices, the NFC application should have the advantages of stable work, low performance requirements for hardware platform and strong portability. This paper first analyzes the research background of this project, and concludes that the main research significance of this project is three points: the first point: the hardware performance of the NFC application studied in this project Low demand, low end of cheap equipment on the use of NFC technology to promote the promotion. Second: the NFC application in this paper has a very strong portability, so that it can be used on the Windows, Nucleus, Android and other platforms to help the penetration of NFC technology to other disciplines and applications. Third: the NFC application breakthrough Google The company limited the function of NFC application and development. Then according to the requirements of the project, we determine the hardware selection of the NFC system and the overall architecture of the software. Select the Samsung Corp S3C6410 chip as the control chip, and the PN65N chip of NJI Pu company as the NFC chip, and choose the UART interface for the data communication. The software architecture is the Android 2.3 operating department. The NFC application is developed in the system, and then it is transplanted to the Nucleus operating system used in the domestic low end mobile phone. Next, according to the NFC protocol, we study the HCI (host interface layer), LLC (logical link layer), DAL (drive abstraction layer), application layer and design and implement UART interface drive for developing Android platform. The LLC layer is designed to develop the data frame structure and working mode of the LLC layer. The HCI layer is designed to develop the data frame structure and working mode of the HCI layer. On this basis, the Android platform NFC application is developed. The program mainly implements the reader and write power, card simulation function, point to point transmission function. Finally, this program In this paper, the DAL layer driver, the reader and write function of the NFC application, the card simulation function, the point to point function and the portability are tested and the results are analyzed. According to the results of the test, the NFC function of the NFC application is stable, the portability is strong, the performance of the hardware platform is low and the project is satisfied. Demand can be applied to low-end devices, which is conducive to the further popularization and application of NFC technology in China.
