[Tinyos-help] Question regarding scheduler modification
Dear all, I am trying to modify tinyos scheduler. If I use Active message components in TinyScheduler, it is not compiled. I have made new component and tried to use it which provides Radio functionality to scheduler. Still, It also doesn't work and gives same error message when I call from TinyScheduler. So, is there any way to add Active Message Components and Radio components in TinyScheduler so that I can distribute task. Thanks in advance. Following is my error message: esc-dumpfile=build/micaz/wiring-check.xml BlinkAppC.nc -lm /opt/tinyos-2.x/tos/chips/cc2420/lpl/DummyLplC.nc:39:2: warning: #warning "*** LOW POWER COMMUNICATIONS DISABLED ***" In component `HilTimerMilliC.AlarmToTimerC': /opt/tinyos-2.x/tos/lib/timer/AlarmToTimerC.nc: In function `Alarm.fired': /opt/tinyos-2.x/tos/lib/timer/AlarmToTimerC.nc(HilTimerMilliC.AlarmToTimerC):71: fired.postTask not connected In component `Atm128SpiC.Arbiter.Arbiter': /opt/tinyos-2.x/tos/system/SimpleArbiterP.nc: In function `Resource.request': /opt/tinyos-2.x/tos/system/SimpleArbiterP.nc(Atm128SpiC.Arbiter.Arbiter):77: grantedTask.postTask not connected /opt/tinyos-2.x/tos/system/SimpleArbiterP.nc: In function `Resource.release': /opt/tinyos-2.x/tos/system/SimpleArbiterP.nc(Atm128SpiC.Arbiter.Arbiter):104: grantedTask.postTask not connected In component `CC2420CsmaP': /opt/tinyos-2.x/tos/chips/cc2420/csma/CC2420CsmaP.nc: In function `CC2420Transmit.sendDone': /opt/tinyos-2.x/tos/chips/cc2420/csma/CC2420CsmaP.nc:201: sendDone_task.postTask not connected In component `CC2420ReceiveP': /opt/tinyos-2.x/tos/chips/cc2420/receive/CC2420ReceiveP.nc: In function `RXFIFO.readDone': /opt/tinyos-2.x/tos/chips/cc2420/receive/CC2420ReceiveP.nc:300: receiveDone_task.postTask not connected In component `CC2420SpiP': /opt/tinyos-2.x/tos/chips/cc2420/spi/CC2420SpiP.nc: In function `Resource.request': /opt/tinyos-2.x/tos/chips/cc2420/spi/CC2420SpiP.nc:113: grant.postTask not connected /opt/tinyos-2.x/tos/chips/cc2420/spi/CC2420SpiP.nc: In function `Resource.release': /opt/tinyos-2.x/tos/chips/cc2420/spi/CC2420SpiP.nc:168: grant.postTask not connected In component `Atm128SpiP': /opt/tinyos-2.x/tos/chips/atm128/spi/Atm128SpiP.nc: In function `SpiPacket.send': /opt/tinyos-2.x/tos/chips/atm128/spi/Atm128SpiP.nc:256: zeroTask.postTask not connected Thanks.

[Tinyos-help] nesc comments
Hello all, is there any mechanism to add comments or annotations to user defined functions to assist other tools when we analyze program in app.c or assembly level. I have found system functions using meaningful sub-routine names in assembly and clear comments in app.c but naming of user defined functions is very unclear. Thank you.

Re: [Tinyos-help] Problem following tutorial's instructions for mote-PC serial communication.
Hello, I used to solve first problem simply unplugging usb connector and connecting it again. I dont know the main cause about this. Second, from your output, your serialPort seems to be working. But, you are not getting result and results display depends how you display them or may be your mote did not send any message to PC. Thanks.

[Tinyos-help] Help needed regarding computation time calculation in Microseconds for Atmega128 Processor
I am using Timer3 as code posted below. I call startCounting() before a task
executes and I call stopCounting after task executes.
But, I am getting variable result. Is there any mistake in my code or
somebody can provide code performing similar job.
#include "printf.h"
uint16_t coarseValues;
uint16_t fineValues;
uint16_t COARSECOMPARE = 0x7FFF;
uint16_t fineOffset = 0x000E;
uint16_t coarseOffset = 0x0021;
uint16_t coarseWasCalled = 0;
module ClockCount
{
provides
{
interface TaskCount as TC;
}
uses interface HplAtm128Compare;
}
implementation
{
async event void HplAtm128Compare.fired()
{
TCCR3B = 0x00;
atomic coarseWasCalled++;
atomic coarseValues++;
TCNT3 = 0x; //Counter3 clear
TCCR3B = 0x09;
}
async command void TC.startCounting()
{
atomic coarseValues = 0;
atomic fineValues = 0;
//Actual Timer/Counter
TCNT3 = 0x;
//Set counter clear on match (Couter Control Registers)
TCCR3A = 0x80;
TCCR3B = 0x09;
//Interupt mask set (Extended Timer Interrupt Mask Register)
ETIMSK = 0x10;
//Compare values (Output Compare Register)
OCR3A = COARSECOMPARE;
}
void calculateFine()
{
uint16_t callOffset = (coarseWasCalled * coarseOffset)/COARSECOMPARE;
//Was Commented
atomic coarseValues = coarseValues + callOffset;
if (coarseWasCalled)
{
atomic fineValues = TCNT3 - coarseOffset;
atomic coarseWasCalled = 0;
}
else
{
//there is a 13 overhead on running the counter
atomic fineValues = TCNT3 - fineOffset;
}
}
async command void TC.stopCounting()
{
TCCR3B = 0x00;
calculateFine();
}
command unsigned int TC.getCoarseValue() {atomic return coarseValues;}
command unsigned int TC.getFineValue() {atomic return fineValues; }
command void TC.setCoarseCompare(uint16_t newCompare)
{

OCR3A = newCompare;
}
command void TC.setFineOffset(uint16_t off)
{
atomic fineOffset = off;
}
command void TC.setCoarseOffset(uint16_t off)
{

}
command void TC.sendValuesToScreen()
{
printf("Fine Value is %u:\n", fineValues);
