参数与类型的参数不兼容

7煌电子 · 发表于 2018-7-12 12:37:01

大家好，程序是从8位单片机移植上来的，错误指示为const u8与I2C_Write的指针u8*不匹配：请教一下怎么修改。错误信息：..\HARDWARE\MY9XX1\MY9XX1.c(104): error:  #167: argument of type "const u8 (*)[4]" is incompatible with parameter of type "u8 *"
      SX_I2C_Write(addr,&sx_reg_val[i-1]);
错误的子函数程序：
void Init_SX(void)
{

u8 i;
u8 addr;

      for(i=0;i<=INIT_FAIL_TIME;i++)//INIT_FAIL_TIME=20
      {
            delay_ms(20);
            SX_I2C_Read(0x10,reg_val);//ID
            if(reg_val[3] != SX_Chip_ID) continue;
            break;
      }

      if(reg_val[3] != SX_Chip_ID)return; //again

      for(i = 1;i <= 48; i++)
      {
   if(i <= 12)
      addr = i-1;
   else if( i <= 16)
      addr = 3 + i;
   else if( i <= 27)
      addr = 8 + i;
   else if( i <= 32)
      addr = 9 + i;
   else if( i <= 48)
      addr = 15 + i;
      SX_I2C_Write(addr,&sx_reg_val[i-1]);
}

                     Write_SX_U_Band_RegVal();
                     SX_Reset_Chip();
                     SX_Trigger();
}
另外一个子函数程序：
const u8 sx_reg_val[48][4] =
{
0xfC,0x4f,0x04,0x00, //REG0

         .
         .
         .
0x00,0x0F,0x00,0x00, //REG3F
}

SX_I2C_Write的子函数程序：
void SX_I2C_Write(u8 reg,u8 *pBuf)
{
      u8 i;

      if(reg <= 0x0b)
{
      analog_reg_val[reg][0] = pBuf[0];
      analog_reg_val[reg][1] = pBuf[1];
      analog_reg_val[reg][2] = pBuf[2];
      analog_reg_val[reg][3] = pBuf[3];
}

      IIC_Start();
      IIC_Send_Byte(SX_Chip_ID);

      reg = reg<<1;
      IIC_Send_Byte(reg);

      for(i=0;i<4;i++)
      {
            IIC_Send_Byte(pBuf);
      }
      IIC_Stop();

}

取地址后再前面增加(u8*)看看，SX_I2C_Write(addr, (u8*)&sx_reg_val);
