ZigBee协议栈 Modbus RTU

处理modbus RTU数据电压 0x00 0x01 0x96 0x40 电流0x00 0x00 0x06 0x73

如下，

//串口接收函数，数据来源于上位机
static void rx0CB(uint8 port,uint8 event)
{
   (void)port;
   uint8 uart0buf[12];//获取控制命令
   unsigned int v_value;
   uint16 i_value;
   uint8 v[3];
   uint8 i[2];

   HalUARTRead(0,uart0buf,12);//参数下发


   if(uart0buf[0]==0x01&&uart0buf[1]==0x03&&uart0buf[2]==0x08)
   {
     v_value=uart0buf[4]*65536+uart0buf[5]*256+uart0buf[6];

     rftx.v_num=v_value/1000;    //3位有效数

     i_value=uart0buf[9]*256+uart0buf[10];
     rftx.i_num=i_value/100;     //2位有效数

     v[0]=rftx.v_num/100+'0';
     v[1]=rftx.v_num%100/10+'0';
     v[2]=rftx.v_num%10+'0';
     HalUARTWrite(1,v,3);


     i[0]=rftx.i_num/10+'0';
     i[1]=rftx.i_num%10+'0';
     HalUARTWrite(1," ",1);
     HalUARTWrite(1,i,2);


   }

}

这是结构体
struct RFTX
{
  uint8 num;
  uint8 relay_state[6];
  uint8 Temp[2];
  uint8 Vcc[2];
  uint16 v_num;
  uint8 i_num;
}rftx={1}; 

这是uint8等定义
typedef signed   char   int8;
typedef unsigned char   uint8;    //无符号1字节

typedef signed   short  int16;
typedef unsigned short  uint16;

typedef signed   long   int32;
typedef unsigned long   uint32;

typedef unsigned char   bool;

typedef uint8           halDataAlign_t;

不知为何最后电压串口数据并不对，电流是正确的
