I keep getting a syntax error, and I am not exactly sure why.
Here is the error of my compilation (make mica2):
In component `RadioSenseToLedsC':
RadioSenseToLedsC.nc: In function `Receive.receive':
RadioSenseToLedsC.nc:117: syntax error before `*'
RadioSenseToLedsC.nc:120: `val' undeclared (first use in this function)
RadioSenseToLedsC.nc:120: (Each undeclared identifier is reported only
once
RadioSenseToLedsC.nc:120: for each function it appears in.)
make: ** [exe0] Erro 1
My .nc file corresponding to this piece of code:
103 event message_t* Receive.receive(message_t* bufPtr,
104 void* payload, uint8_t len) {
105
106
107 call Leds.led1Toggle();
108 if (len != sizeof(radio_sense_msg_t)) {return bufPtr;}
109 else {
110 am_addr_t tt = call AMPacket.source(bufPtr);
111 uint16_t ttt = (uint16_t) tt;
112 char str[64];
113 sprintf(str,"%d: Recebi msg do %d",TOS_NODE_ID, ttt);
114 printStr(str);
115
116
117 radio_sense_msg_t* rsm = (radio_sense_msg_t*)payload;
118
119 uint16_t val = rsm->data;
But if I move the content of the lines 110~114 to BEFORE the IF
condition it works perfectly! Why is that? Can someone explain to me
where is my SYNTAX error?
Actually.. Why does it says that val is not declared too?
ps.: I use the sprintf only to convert that all to a single string, the
printStr is part of another lib, used to print it in the middle of a
simulation (I am not using TOSSIM, I am trying to use avrora)
Thanks in advance,
Fernando.
