Hi, i have a problem. I have to take datas from two different sensors on
Tmote-Sky(Light and Temperature) and send on two differente radio channel to an
other tmote-sky. After the transmission, radio turn off and then restart one
second before the next ADC sampling (I hope!).
I wrote this code but the transmitter doesn't work well
configuration SenseToRfm {
// this module does not provide any interface
}
implementation
{
components Main, SenseToInt, IntToRfm, IntToRfm_8, IntToLeds, TimerC, ADCC,
HamamatsuC as Sensor, DemoSensorC as Sensor_1, SenseToInt_PP;
Main.StdControl -> SenseToInt;
Main.StdControl -> IntToRfm;
Main.StdControl -> SenseToInt_PP;
Main.StdControl -> IntToRfm_8;
SenseToInt.Timer -> TimerC.Timer[unique("Timer")];
SenseToInt.TimerControl -> TimerC;
SenseToInt.ADC -> Sensor.PAR;
SenseToInt.ADCControl -> Sensor;
SenseToInt.IntOutput -> IntToRfm;
IntToLeds <- SenseToInt.IntOutput;
SenseToInt_PP.Timer -> TimerC.Timer[unique("Timer")];
SenseToInt_PP.TimerControl -> TimerC;
SenseToInt_PP.ADC -> Sensor_1;
SenseToInt_PP.ADCControl -> Sensor_1;
SenseToInt_PP.IntOutput -> IntToRfm_8;
}
SenseToInt and SenseToInt_PP are the same, the only change is the sensor.
The code of IntToRfm is:
includes IntMsg;
configuration IntToRfm
{
provides {
interface IntOutput;
interface StdControl;
}
}
implementation
{
components IntToRfmM, TimerC, GenericComm as Comm
// HPLPowerManagement is only needed for AVR based platforms
#ifdef __AVR__
, HPLPowerManagementM as PM
#endif
;
#ifdef __AVR__
CountSleepRadioM.PowerManagement -> PM;
CountSleepRadioM.Enable -> PM.Enable;
#endif
IntOutput = IntToRfmM;
StdControl = IntToRfmM;
StdControl = TimerC;
IntToRfmM.Send -> Comm.SendMsg[AM_INTMSG];
IntToRfmM.SubControl -> Comm;
IntToRfmM.Timer -> TimerC.Timer[unique("Timer")];
}
and IntToRfmM is:
includes IntMsg;
includes Timer;
module IntToRfmM
{
uses {
interface StdControl as SubControl;
interface SendMsg as Send;
interface Timer;
}
// these are only needed for Atmel AVR based platforms
#ifdef __AVR__
uses interface PowerManagement;
uses command result_t Enable();
#endif
provides {
interface IntOutput;
interface StdControl;
}
}
implementation
{
bool pending;
TOS_Msg data;
command result_t StdControl.init() {
pending = FALSE;
#ifdef __AVR__
call Enable();
call PowerManagement.adjustPower();
#endif
call SubControl.init();
return SUCCESS;
}
command result_t StdControl.start()
{
call SubControl.start();
return SUCCESS;
}
command result_t StdControl.stop()
{
return SUCCESS;
}
command result_t IntOutput.output(uint16_t value)
{
IntMsg *message = (IntMsg *)data.data;
if (!pending)
{
pending = TRUE;
message->val = value;
atomic {
message->src = TOS_LOCAL_ADDRESS;
}
if (call Send.send(TOS_BCAST_ADDR, sizeof(IntMsg), &data))
return SUCCESS;
pending = FALSE;
}
return FAIL;
}
event result_t Send.sendDone(TOS_MsgPtr msg, result_t success)
{
if (pending && msg == &data)
{
pending = FALSE;
signal IntOutput.outputComplete(success);
}
call SubControl.stop();
call Timer.start( TIMER_ONE_SHOT, 4000 );
return SUCCESS;
}
event result_t Timer.fired()
{
call SubControl.start();
return SUCCESS;
}
}
The difference between IntToRfm and IntToRfm_8 is the value of AM_INTMSG (4 for
IntToRfm, 8 for IntToRfm_8). I would like to know if the code is correct and
whick are the bugs. Please help.
Thanks
Simone
