oled问题 求好心人帮忙看看

好学者

为什么我自己在oledfont.h里面定义了一个新的汉字数组 unsigned char hanzi_1616[5][32]={   

{0x21,0x00,0x21,0x22,0x22,0xA2,0x22,0xA4,0x24,0xA8,0x3B,0xE0,0xE4,0xA0,0x24,0xA0,0x3C,0xA0,0xAB,0xF0,0x6A,0xA8,0x32,0xA4,0x22,0xA6,0x2E,0xA0,0x20,0x20,0x00,0x00},/*"龚",0*/

{0x08,0x20,0x06,0x20,0x80,0xFF,0x6F,0x00,0x00,0x80,0x08,0x80,0x1F,0xF8,0xE8,0x88,0x2C,0xC8,0x2A,0xA8,0x28,0x8A,0x28,0x89,0x2F,0xFE,0x20,0x88,0x20,0x88,0x00,0x00},/*"海",0*/

{0x02,0x02,0x02,0x02,0x04,0x42,0x04,0x42,0x0A,0x52,0x12,0x4E,0x22,0x42,0xC3,0xFE,0x22,0x42,0x12,0x46,0x0A,0x5A,0x0A,0x42,0x04,0x42,0x06,0x02,0x04,0x02,0x00,0x00},/*"金",0*/

{0x00,0x00,0x0A,0x00,0xF2,0xFC,0x52,0x80,0x12,0x80,0xFF,0xFF,0x12,0x84,0x12,0x86,0x12,0xFC,0x00,0x00,0x3F,0xF0,0x00,0x02,0x00,0x01,0xFF,0xFE,0x00,0x00,0x00,0x00},/*"制",1*/

{0x01,0x00,0x02,0x00,0x04,0x00,0x1F,0xFF,0xE0,0x00,0x44,0x00,0x18,0x00,0x30,0x00,0xDF,0xFF,0x12,0x20,0x12,0x20,0x12,0x20,0x16,0x20,0x12,0x60,0x10,0x20,0x00,0x00},/*"作",2*/

};

在oled.c里面不能用啊   ..\HARDWARE\OLED\oled.c(177): error:  #20: identifier " hanzi_1616 " is undefined   但是在oled.c里面定义就可以用了显示汉字正常    刚开始以为是名字打错了 后面发现不是这个问题！   求解？？？

冰封嗜魔

你在oled.c加头文件oledfont.h了吗？

好学者

那个 添加了  他前面的例程里面已经定义了两个数组  例程里面的两个可以用 而我就加了一个数组就不行

正点原子

头文件申明了:unsigned char hanzi_1616[5][32];没有?

好学者

那个是在oledfont.h 定义了一个变量还要声明啊    又不是函数啊？

好学者

我把代码上传上去吧   问题在oled.c的的177 和178那两条语句上？ 有一个可以 一个又错误

在使用的C文件对应的头文件里输入extern unsigned char hanzi_1616[5][32];
