Design And Realization Multi-Functional Digital Learning Assistant System Based On Linux

The application of Embedded Systems is spreading by the development of information technology. Consume-oriented electronic is one of the primary applications, the Digital Learning Assistant is typical and developed rapidly among which. Multi-functional Digital Learning Assistant not only provides all of the traditional Learning Assistant's functionalities but also enhances the information management and multimedia application's functionalities. Therefore, it can be used as both PDA and PMP. The market potential of multi-functional Learning Assistant is tremendous with the development of mobile computing, embedded techniques and functionality of Learning Assistant, even along the handle embedded devices field.Based on the study of Linux and Qt/Embedded, the design of the multi-functional Learning Assistant is researched in this thesis. The design, debugging and implement of the software system are the keys.Firstly, the choosing criterion of system hardware is discussed including processor, Flash, LCD touch-screen, storage cards, extended interfaces and...
