在emwin中显示字库芯片GT23L24M0140的字模
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
显示效果:
