Embodiment one
The embodiment of the present invention one discloses a kind of method for information display, and the method can be applicable to electronic equipment, realizes on the display interface of electronic equipment, carry out corresponding content display.With reference to figure 1, the method comprises the steps:
S101: receive display request, described display request comprises object content to be shown, shows the font ID of the font that described object content adopts.
S102: obtain the font information corresponding with described font ID from the fontlib be stored in advance in External memory equipment.
S103: the described font information obtained is loaded in default memory devices.
S104: call the described font information in described memory devices, utilizes described font information to show described object content.
The inventive method specifically can be applicable in the embedded display device of low and middle-end.
Due to MCU (the Micro Control Unit of the embedded display device of existing low and middle-end, processor) inside do not have MMU (Memory Management Unit, memory management unit), the information of External memory equipment cannot be read, and program code cannot be loaded into outside SDRAM (Synchronous Dynamic Random Access Memory, synchronous DRAM) middle operation, cause its font file can only deposit therein in Flash, but the finite capacity of internal storage space, cannot integrated complete fontlib, multi-font for user is selected to bring extreme difficulties.
For overcoming the problems referred to above, the present invention is based on the implementation of exterior storage, access, in advance complete fontlib is left in external memory storage, such as, leave in the devices such as outside SPI (Serial Peripheral Interface, Serial Peripheral Interface (SPI)) Flash.
Simultaneously, for ensureing that the MCU of the embedded display device of low and middle-end can conduct interviews to external memory storage, the present invention makes following upgrading amendment to GUI (Graphical User Interface, graphic user interface) the system bottom source code in existing display device MCU:
1) drive layer in the access of GUI font memory, access location is adjusted to external memory storage;
2) according to the difference of the shared byte number of Chinese and English, distinguish and read side-play amount, and carry out shifting function according to the order of sequence.
Namely from the mode and font of accessing font, the present invention supports that the bottom source code of type two angles to GUI system adjusts, achieves the access function of MCU to external memory storage.
On this basis, as shown in Figure 2, after the embedded display device power-up initializing of low and middle-end, when receiving user or display device presets the display request to certain object content of (as start display is arranged), the principal function Main be stored in described display device Flash is loaded in internal memory device SDRAM and runs by its MCU, MCU reads corresponding font file from the fontlib of outside Flash simultaneously, and the font file of reading is loaded in internal memory and inner SDRAM and calls for principal function Main, to realize at LCD (Liquid Crystal Display, liquid crystal display) on described object content is shown.
Wherein, the present invention is specifically combined file system technology, all fonts is used as an overall file, when accessing word-base data, uses the form of file bag (* .txt file) to read, write font information.
To sum up, the present invention is by the bottom source code of amendment GUI system, and be combined file system technology, achieve exterior storage and the access of the font of the embedded display device of low and middle-end, because external memory device can carry out spread according to actual storage demand, thus, instant invention overcomes the problem that font file in prior art is limited by the restriction of display device storage space, achieve complete character library access, the multi-font for user is selected to provide support, improves Consumer's Experience; Meanwhile, release the inside Flash that font takies, optimize system performance.
