Question

IAR使用结构变量问题（msp430）

#define uchar unsigned char

struct FindGB16
{
uchar Index[3];
uchar data[32];
};

struct FindGB16 GB16[]= //为结构变量初始化
{
"我", 0x20,0x24,0x24,0x24,0xFE,0x23,0x22,0x20,
0xFF,0x20,0x22,0xAC,0x20,0x30,0x20,0x00,
0x00,0x08,0x48,0x84,0x7F,0x02,0x21,0x10,
0x09,0x06,0x1A,0x61,0x80,0xE0,0x00,0x00,

"有", 0x04,0x04,0x04,0x84,0xE4,0x3C,0x27,0x24,
0x24,0x24,0x24,0xF4,0x24,0x06,0x04,0x00,
0x04,0x02,0x01,0x00,0xFF,0x09,0x09,0x09,
0x09,0x49,0x89,0x7F,0x00,0x00,0x00,0x00,

"一", 0x80,0x80,0x80,0x80,0x80,0x80,0x80,0x80,
0x80,0x80,0x80,0x80,0x80,0xC0,0x80,0x00,
0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,

};

请问我这样初始化有什么问题吗？
Error[Pe101]: "FindGB16" has already been declared in the current scope (at line 3) C:\Users\Administrator\Desktop\TFT2.4\chinese.h 3

Error[Pe148]: variable "GB16" has already been initialized (at line 9) C:\Users\Administrator\Desktop\TFT2.4\chinese.h 9
为啥报错呢？

Answer 1

FindGB16结构体已经定义了，你下面定义的时候只需要const FindGB16 GB16[]= {...};
另外
struct FindGB16
{
uchar Index[2];// 汉字占两个字节，所以定义成2，如果定义成3下面定义GB16数组时应该定义成 "我\0"的形式
uchar data[32];
};
