Question

我在编译时遇到以下错误：

MenuNavigationApp.c:58: error: array type has incomplete element type
MenuNavigationApp.c:43: error: storage size of ‘lcd' isn't known
MenuNavigationApp.c:338: error: too many arguments to function ‘ucSCPowerUp'

这是我的代码：

int ZealMain()
{
    UCHAR ucStatus;
    struct DisplaySettings lcd ;                       /* line 43 */
    UCHAR seq[]={'0','1','2'},ucKey=0;
    BOOL bStatus;
    UCHAR ucGetStringBuf[3];
    UINT ucGetStringBuf1,uiTimeOut=0;
    UINT ucGetStringBuf2;
    lcd.bFullScreen=1;
    lcd.ucStartPoint=5;
    lcd.ucEndPoint=50;
    lcd.bSelectOption=1;
    lcd.bModeSelect=0;
    lcd.ucSelectedItem=0;

    int uitimeout=30;

    struct FunctionInfo Zealperiph[]={               /* line 58 */

        /* Function information array */

        {"LCD",1,"0",NULL,NULL},
        {"DISPLAY CENTER",2,"00",vLcdDispCenter,NULL},
        {"Display CIRCLE",2,"01",vLcdDispCircle,NULL},
        /* a lot more of these ... */
        {"PRINT DATA",2,"70",vPrintData,NULL}};

    ucStatus=ucMenuNavigation("ZEAL INTERACTIVE",Zealperiph,33,0,uiTimeOut,&lcd);
    if(ucStatus!=1)
        bLCDDispCenter("Values are Incorrect",TIMES8_13);
}

void vPowerUp()
{
    UCHAR ucAtrBuff[50],ucAtrlen,ucStatus;
    ucSCPowerUp(ucAtrBuff, &ucAtrlen,0x27);        /* line 338 */
    vGetCardStatus();
}

Answer 1

你在哪里有

的定义

struct DisplaySettings lcd？似乎不见了。

Answer 2

行号错误。图43和58显示结构定义超出了它的范围用来。尝试检查已定义它的位置或使用此结构的extern声明...并且第338行的错误显示..在某些地方你可能已经在你的代码中提供的声明中给出了更多args bt ...

C错误：'lcd'的存储大小未知
