在emwin中显示字库芯片GT23L24M0140的字模


本文博客链接:http://blog.csdn.net/jdh99,作者:jdh,转载请注明.


环境:

主机:WIN8

开发环境:MDK5.13

mcu: stm32f407VGIGH6

emwin: STemWin5.22

字库芯片:GT23L24M0140


说明:

项目中需要显示生僻字,所以不能使用GB2312,选择字库芯片GT23L24M0140,支持GB18030标准。

难点在于在emwin中嵌入此字库芯片的字符,emwin本身有一套接口,所以必须满足这套接口才能显示。

解决的方法是先移植在emwin中显示sd卡/flash中字库的函数,然后将具体读取函数替换成直接读取字库芯片的函数。

字库芯片的驱动程序见此文:驱动字库芯片GT23L24M0140
