无外部IC\FLASH，不用SD卡显示汉字程序代码分享（汉字内码）

龙胜阳子 · 发表于 2013-10-6 05:25:50

用了几个小时弄了个小程序，主要用于字数不多但型号字体变化较多的场合
效果如下

typedef struct typFNT_GB16                 // 汉字字模数据结构
{
       unsigned char Index[2];               // 汉字内码索引
         char Msk[32];                       // 点阵码数据
};

你这方法我早在AVR时代用过了，我还以为你说的是不用外部IC和FLASH甚至SD卡，直接根据汉字GBK码，来用算法算出字体的点阵来，然后显示，如果真这么牛×，此贴可以申酷了。

大神，我最近在做显示汉字，把你的代码添加到ALIENTEK MINISTM32 实验11 TFT液晶显示实验里，怎么不显示？求解，谢谢

怎么直接复制你的代码会报错的，，，main.c(53): error: #513: a value of type "const char *" cannot be assigned to an entity of type "u16"
