exit code=1.

问题原因：

sx1276.c:70行调用函数：Value = lpTypefunc.lpByteReadfunc(); lpByteReadfunc()函数没有形参，需要加上void。

1. typedef struct {
   

2.     
   

3.    void (*lpByteWritefunc)(unsigned char src);
   

4.    unsigned char (*lpByteReadfunc)();
   

5.    void (*lpSwitchEnStatus)(cmdEntype_t cmd);
   

6.    void (*paSwitchCmdfunc)(cmdpaType_t cmd);
   

7.    void (*lpRecvDataTousr)(unsigned char *lpbuf,unsigned short length);
   

8.    
   

9. } lpCtrlTypefunc_t;

修改为：

1. typedef struct {
   

2.     
   

3.    void (*lpByteWritefunc)(unsigned char src);
   

4.    unsigned char (*lpByteReadfunc)(void);           /* 加上void */
   

5.    void (*lpSwitchEnStatus)(cmdEntype_t cmd);
   

6.    void (*paSwitchCmdfunc)(cmdpaType_t cmd);
   

7.    void (*lpRecvDataTousr)(unsigned char *lpbuf,unsigned short length);
   

8.    
   

9. } lpCtrlTypefunc_t;

1. unsigned char RF_SPI_READ_BYTE()
   

2. {    
   

3.    unsigned char j;
   

4.    unsigned char i;
   

5.    j=0;
   

6.    for (i = 0; i < 8; i++){    
   

7.      RF_CKL_H;
   

8.      j = (j << 1);                         // shift 1 place to the left or shift in 0 //
   

9.      if( SX1278_SDO )                             // check to see if bit is high //
   

10.        j = j | 0x01;                      // if high, make bit high //
    

11.                                                  // toggle clock high //
    

12.      RF_CKL_L;                              // toggle clock low //
    

13.    }
    

14.   
    

15.    return j;                                // toggle clock low //
    

16. }

17. 
    

修改为：

1. unsigned char RF_SPI_READ_BYTE(void)         /* 加上void */
   

2. {    
   

3.    unsigned char j;
   

4.    unsigned char i;
   

5.    j=0;
