未解析的符号,首先在

unresolved symbol , first referenced in

我有 4 个文件(2 个 headers,2 个来源):

我在 azt 中加入了 lcd。[​​=16=]

在 lcd 中有一个函数 WriteMsg 在 azt 中被调用, 它工作正常。

但是当我在lcd.c中添加对该函数的调用时,出现以下错误

Description Resource    Path    Location    Type
unresolved symbol WriteMsg, first referenced in ./Includes/AutoZeroTracking.obj Joe1000         C/C++ Problem

我知道我首先在azt文件中引用了它,但是在其他地方引用了这个函数,我没有这个问题。

这是lcd.h:

#ifndef MSP
#define MSP
#include <msp430g2553.h>
#endif
#include "Utilities.h"
#include "Declarations.h"

#ifndef INCLUDES_LCD_H_
#define INCLUDES_LCD_H_
#define LCD_CALL 1

void InitLCD(unsigned char SDA,unsigned char SCL,unsigned char slaveAddress);
void StartLCD();
inline int ReadyToSend();
void SendToLcd(unsigned char* data, int size);
void WriteToLCD(int clearScreen);
void switchFrom8To4Bits();
void write2x4Bits(unsigned char bits, int is_data);
void writeCommand(unsigned char command);
inline void writeData(unsigned char data);
void ClearScreen();
void WriteWeight();
void WriteWeightMode();
inline void WriteMsg(const char* msg, int msgLen,char msgLocation,int maxDigits);
inline void WriteNum(long num,char location,int maxDigits);
void WriteTare(char num);


#endif /* INCLUDES_LCD_H_ */

这是 azt.h:

#ifndef INCLUDES_AUTOZEROTRACKING_H_
#define INCLUDES_AUTOZEROTRACKING_H_
#include "Declarations.h"
#include "LCD.h"
#include "Utilities.h"

void AZTSetup();
void AZTProcess();

void DisplayAZT();

void GetPreviousAZT();
void GetNextAZT();

void KeyPressedAZTMode(char keyPressed);

inline char HasAZTStopped();

#endif /* INCLUDES_AUTOZEROTRACKING_H_ */

代码在azt.c

void DisplayAZT()
{
    WriteMsg(AZT[m_curr_azt],AZTLen[m_curr_azt],0x8A,5);
}

lcd.c

中的调用
void WriteWeight()
{
    WriteNum(CountBy[cnt_by_idx],0x80,2);
    WriteNum(NOD[n_o_d_idx],0x83,5);
    WriteNum(max_weight,0x89,6);
    WriteNum(idx_decimal_point,0x90,1);
    WriteMsg(AZT[az_tracking_idx],AZTLen[az_tracking_idx],0x9A,3);
    WriteNum(BaudRate[baud_rate_idx],0xC0,6);
    WriteNum(PP2Z[percent_p2z_idx],0x9E,2);
    WriteNum(wt_zero,0x94,10);
    WriteNum(wt_slope,0xD4,10);

    /*int i = 0;
    for(i = 0; i < WEIGHT_ARR_LEN ; i++)
    {
        if(display_weight[i] != IGNORE_CHAR)
            writeData(display_weight[i]);
    }*/
}

提前致谢。

我删除了内联并编译。
