[Abstract]:Nowadays, with the development of economic globalization and the continuous popularization of electronic commerce, logistics industry plays a more and more important role. The application of information technology has become one of the important means for logistics enterprises to improve work efficiency and reduce operating costs. Logistics PDA, as a convenient tool for information collection and transmission, is undoubtedly an important tool for logistics informatization and has a very important application prospect. In this paper, through the in-depth study of the key technologies of logistics PDA hardware and software, a PDA. for logistics industry is designed and implemented. This paper focuses on the following aspects of the work: 1. Through the in-depth study of logistics PDA hardware and its related knowledge, the underlying hardware architecture of logistics PDA is built. According to the characteristics of hardware and pin interface, the underlying driver of logistics PDA is designed and implemented. two銆
