Hi all,
Recently I have been doing some simple experiment in Imote2.I want to send the
data from one mote to another,which was defined in my local C file(not from the
sensor) .The interface I use are SendMsg and ReceiveMsg.When the Timer
fired,the data would be sent.If the message is sent successfully,the green
indicator will flash.
------------------------------------------------------------------------------------------
event result_t Timer.fired(){
uint16_t j,k;
struct ProcessnodeMsg *pack;
while(startPos < MAX_BUFFER) //The variable starPos was first
assigned to 0 in the global space;
{
k = 0;
pack = (struct ProcessnodeMsg *)msg[currentMsg].data;
for(j = startPos;j<startPos+BUFFER_SIZE&&j<MAX_BUFFER;j++)
{
pack->data[k] = (uint8_t)inputdata[k]; //inputdata[256][256]
was defined in 'inputfile.h'
k++;
}
pack->sourceMoteID = TOS_LOCAL_ADDRESS;
pack->sequenceNum = ++seqNum;
post dataTask();
if(startPos>=MAX_BUFFER)
startPos = 0;
else
startPos = j;
}
call Leds.greenToggle();
return SUCCESS;
}
}
-------------------------------------------------------------------------------------------
task void dataTask() {
//Try to send the packet.
if (call DataMsg.send(TOS_BCAST_ADDR, sizeof(struct ProcessnodeMsg),
&msg[currentMsg]))
{
atomic {
currentMsg ^= 0x1;
}
call Leds.yellowToggle();
}
}
--------------------------------------------------------------------------------------------
But when I compile the code into Imote2 ,it doesn't work!
I don't know what the problem is.Could someone help me?
