Abstract: Compared with touch-tone operation photo frame, touch-screen digital photo frame possesses some standing-out features such as huge storage capacity, and good software maintainability. Touch-screen digital photo frame introduces the embedded real-time systems through the application of Mini2440 analog digital photo frame system and Modbus protocol. C/OS-II real-time operating system is added up to the newly developed platform, which is featured for photo show, slide show and system configuration. This study plays a significant role in demonstrating advantages of application of C/OS-II system, which contributes to a high quality of photos, short response time, large storage space and user-friendly interface.

 

Keywords: Digital photo frame, C/OS-II, Real-time Operating System, Mini2440, Touch-screenone.
