Hi all,
I am trying to send control command from PC to mote by UART. The program run on
PC was written in C#, but it seems that my note cannot switch to case
CMD_TYPE_GETSAMPLE.
Maybe this because my CRC field is 0?
Thanks in advance!!!
According to TOS_Msg struct, my C# code is:
//GetSample Command (struct) is encapsulated in TOS_Msg struct.
//TOS_Msg struct:
//|<---addr--->|<---type--->|<---group--->|<---Len--->|<---data[TOSH_DATA_LENGTH]--->|<---CRC--->|
// 2 bytes 1 byte 1 byte 1 byte
Byte array up to 29 bytes 2 bytes
// 0x007e (126) 08 0x7d (125) 09
GetSample Command (9 bytes) 00
//GetSample Command (struct):
//|<---wSrcAddr--->|<---wDesAddr--->|<---wSenderAddr--->|<---wNextIoAddr--->|<---bCmdType--->|
// 2 bytes 2 bytes 2 bytes
2 bytes 1 byte
// 0x007e 1
1 0 2
Byte[] TOS_Msg_ = new Byte[16] { 00, 126, 08, 125, 09, 00, 126, 00, 01,
00, 00, 00, 00, 02, 00, 00 };
........
private void Form1_Load(object sender, EventArgs e)
{
serialPort1.PortName = "COM3";
serialPort1.BaudRate = 115200;
serialPort1.DataBits = 8;
serialPort1.StopBits =System.IO .Ports .StopBits .One;
serialPort1.Parity =System.IO.Ports .Parity .None;
}
......
serialPort1.Write (TOS_Msg_,0,16);
My main Mote code is:
// Msg type ID
enum
{
AM_MOTE_MSG =8,
};
// CMD types
enum
{
CMD_TYPE_GETSAMPLE =2,
};
// CMD structs
typedef struct _CMDGETSAMPLE
{
uint16_t wSrcAddr;
uint16_t wDestAddr;
uint16_t wSenderAddr;
uint16_t wNextIoAddr;
uint8_t bCmdType;
} CMDGETSAMPLE, *LPCMDGETSAMPLE;
/********************************************
* Task to evaluate a command and execute it if it is a supported command.
* @return Return: None
********************************************/
TOS_MsgPtr m_pCurrentMsg;
task void cmdInterpret()
{
LPCMDGETSAMPLE pCmdGetSample;
// Check
if(m_pCurrentMsg==NULL)
return;
pCmdGetSample=(LPCMDGETSAMPLE)(m_pCurrentMsg->data);
switch(pCmdGetSample->bCmdType)
{
.......
case CMD_TYPE_GETSAMPLE:
call Leds.greenOn();
break;
}
// Inform CommRecv to free m_pCurrentMsg
call CommRecv.recvDone(m_pCurrentMsg, SUCCESS);
}
/********************************************
* Called upon message reception
* @return Returns a pointer to a TOS_Msg buffer
********************************************/
event result_t CommRecv.recv(TOS_MsgPtr pMsg)
{
m_pCurrentMsg=pMsg;
post cmdInterpret();
return SUCCESS;
}
} // end of implementation
