在编译的时候，出现
..\HARDWARE\9325\GB32_32.h(26): error:  #144: a value of type "char *" cannot be used to initialize an entity of type "unsigned char"
这样的问题


而我在自作16*16的点阵字库时候就没有出现这样的情况，请各位大侠帮帮我找找问题，先在此谢谢啦

你这16*16不出问题???
1个数组里面,即有字符串,还有数字,不报错???

是不会出问题的，你把结构体的无符号字符型改为有符号字符型就可以了。其他看不出来什么问题！
以下是我的部分字库，在MDK编译是没问题的。

我试过用char 可是还是有错

上面是编译的提示

改为:typedef struct FNT_GB32Type

   unsigned char Index[2];
   unsigned char  Msk[128];
};

但是我今天又遇到一个新的问题，我自己自作了一个32*32的字库，但是我大概只能存放31个字，后面的字就没有办法显示，而且后面自作的字库，都会以最后一个字的形式显示，这是为什么？

仿真跟踪一下看看吧.
