The course of C language in the specialty of the computer science and technology is transferred to the embedded platform to prompt the teaching effect.Correspondingly, Keil C is used as the development environment, and the new experiment board with a serial of external peripherals is designed based on the 8051 family MCU.The case teaching method is adopted to increase the appeal, in which the full knowledge of C language is trained. By forming the practical systems or devices with C language on the boards, the students' passion is stimulated for programming due to their recognition for the power and practicality of C language.At last the students are familiar with C language, and begin to cognize the embedded system.
To increase the agility of the chain store operation with the information technology, the communication system is proposed with the mobile networks to link the headquarters with the chain stores distributed widely. In the store, the mobile is attached to POS with USB, and the data exchanging service is developed on the mobile to report the sale data and to download the updated data. At the headquarters, a communication server is established to provide the data service for the mobiles with the customized web service methods. In this way, the sale data of all the chain stores can be gathered in time, which is the groundwork for the business intelligence system.
