Hello!
I was wondering if you could shed any light on the
errors i am having. I am following this tutorial for mote to mote
communication http://docs.tinyos.net/index.php/Mote-mote_radio_communication
and
it generates the following errors:
[r...@xps BlinkToRadio]# make micaz install mib510,/dev/ttyUSB0

make: *** [exe0] Error 1
The code that is throwing these errors is:
#include <Timer.h>
#include "BlinkToRadio.h"
module BlinkToRadioC {
uses interface Boot;
uses interface Leds;
uses interface Timer<TMilli> as Timer0;
uses interface Packet;
uses interface AMPacket;
uses interface AMSend;
uses interface SplitControl as AMControl;
uses interface Receive;
}
implementation {
bool busy = FALSE;
message_t pkt;
uint16_t counter = 0;
event void Boot.booted() {
call AMControl.start();
}
event void AMControl.startDone(error_t err) {
if (err == SUCCESS) {
call Timer0.startPeriodic(TIMER_PERIOD_MILLI);
}
else {
call AMControl.start();
}
}
event void AMControl.stopDone(error_t err) {
}
event void Timer0.fired() {
counter++;
call Leds.set(counter);
if (!busy) {
BlinkToRadioMsg* btrpkt = (BlinkToRadioMsg*)(call
Packet.getPayload(&pkt, NULL));
btrpkt->nodeid = TOS_NODE_ID;
btrpkt->counter = counter;
if (call AMSend.send(AM_BROADCAST_ADDR, &pkt, sizeof(BlinkToRadioMsg))==
SUCCESS) {
busy = TRUE;
}
}
}
event message_t* Receive.receive(message_t* msg, void* payload, uint8_t len)
{
if (len == sizeof(BlinkToRadioMsg)) {
BlinkToRadioMsg* btrpkt = (BlinkToRadioMsg*)payload;
call Leds.set(btrpkt->counter);
}
return msg;
}
event void AMSend.sendDone(message_t* msg, error_t error) {
if (&pkt == msg) {
busy = FALSE;
}
}
}
I can't see what I have done wrong!
Thanks for any assistance,
