Application Development, Based Framebuffer Anniversary Digital Photo Frame

The digital photography emerged has caused the digital picture frame development inevitably, because only had less than 35% digital picture to print. The digital picture frame's basic principle is uses the ordinary picture frame the modelling, changes into the liquid crystal display monitor the original picture frame's in picture part, is joined to the power source, the storage medium and so on, causes in the identical picture frame to be possible to circulate the broadcast picture, has the superiority compared to the ordinary picture frame's sole demonstration function. Starts from 2007, the digital picture frame's market attention starts to increase sharply. In 2008, the digital picture frame market is presents the high speed development the situation, has the extremely high potential market value.The thesis take Mini2440+Fedora12 the embedded development platform as an example, mainly introduces the digital picture frame the principle and the digital picture frame software's research and development work. Inside involves to the embedded Linux programmer's basic skill, like Makefile, gcc, gdb, open the source storehouse the use and so on. As derivation, will also understand c the pretreatment process. Since demonstrates the picture, certainly also has many file operations (i.e. to picture operation), simple open, will read and so on operations certainly will appear very simple, but when you will unify the virtual file system, when knowledge and so on advancement will consider, had certain difficulty. This article also used the graphics knowledge to go to picture some, since has realized more dynamic effects.the this design's core is based on the ARM platform system transplant and the embedded c programming. According to system's system design mentality choice appropriate hardware combination, based on this carries on the c procedure the compilation and the execution.
