摘要

为了解决C/GUI中文字库占用空间大与MCU内部存储空间有限的矛盾

实现C/GUI对中文更全面完整的支持

对C/GUI外置汉字字库的实现方法进行研究

提出了将汉字字库存储于外置spi flash芯片的解决方案。首先对汉字存储相关的数据结构进行研究

编写spi flash芯片驱动程序

之后利用PC串口编写软件和串口中断处理函数将字库文件写入到外置flash芯片中。然后在中文字库成功写入flash芯片内部的基础上

对C/GUI中与字符显示相关的内核函数进行修改

完成对所有显示字符属性的判断

从而实现C/GUI对外部中文字库的支持。试验结果表明

外置字库中的汉字成功地在液晶屏上显示出来。存储于外置spi flash芯片中的字库能被C/GUI正常的调用和显示。外置spi flash字库节省了MCU内部有限的存储空间

具有较好的通用性和灵活性。

Abstract

The word stock of C/GUI takes up too much space but the storage space of MCU is limited. In order to solve this contradiction

the method to realize the external Chinese word stock of C/GUI is explored. The scheme storing the word stock in the external spi flash chip is put forward. And this scheme supports the Chinese for C/GUI more comprehensive and more complete. First

the data structure related to Chinese character's storage are studied. The driver program of the spi flash is written and the word stock file is stored in the external flash chip through the PC serial port software and serial port interrupt handler. Then

the kernel functions related to the character display is modified to judge the character properties

thus making C/GUI support the external Chinese word stock based on storing the word stock in the flash chip successfully. Results of the trial indicates that the Chinese character stored in the external chip can be displayed on the ILI9320 LCD and the word stock stored in the external chip can be called and displayed by the C/GUI normally. Storing the word stock in the external spi flash chip saves the MCU space and possesses favorable commonality and flexibility.
