Hi Micha,
How do you know if the timer fails to fire?
I experienced the same problem before. Whenever the timer fires, a log is
sent to the UART. If no log is received when a timer is supposed to fire,
the timer is regarded to fail to fire. This turns out wrong because no log

Hi Micha,
could you show us the wiring code for the timer, how you initialize the
timers and how you handle the firing event? Does it fire when started by
other functions? (e.g. a simple Timer.start) Did you use the unique()

Please note that the us counter is driven by the DCO, which stops when

Hello everybody,
I wrote a small program to generate a 16 KHz PWM signal on OC3A which
corresponds to pin 26 on the IRIS 51 pins connector. Assuming that

PRR1 &=~(1 << 3); // enable Timer 3

Thanks for the quick explanation. That makes perfect sense. I was looking at

Thanks again.

Hi all,
I have a problem using two timers under tinyos-2.x with micaz modes. I have my
code ín one file and tried it. I use two timers, one, to start a function
periodic and one to timeout this function and use the leds for debugging. For
the Timeout timer I use the red led and another led for the
TEP102 should be useful to you:

That depends.
In tinyos-1.x, TimerC module is in milli-second *granularity. And the
minimum interval is 3 milli-second. The maximum interval is uint32_t *
*In T2, besides milli-second granularity, * *granularity of micro-second is
also supported. You can also use 32KHz clock if necessary.*

what is the minimum and maximum interval for timers of tmotesky kit

If the received packet length field is 0 then I have no clue.
I don't know what having the destpan field changed means either.
Assuming that you are using a standard TOSBase basestation
and your sending program is not making mistakes, you should see
all your packets, either full or dropped because
hi ,
I am using Listen program, but some packets are received with payload 0 and
some are complete. As I am increasing the Load in the network, the frequency
of full pactes are dropping...

That's a little fast for mica2s but should be ok for devices with
the CC2420 radio. But you should see the full packet no matter what.
What are you using to look at the received messages and how are you
changing the lengths?

Hello Everyone,
I have one question regarding how much tinyos code take time to execute a
application. Becaus ein my application, the timer is fired after every 32
millisecond and receiver node is receiving nearly 30 packets each of 40
bytes. It is receiving only the header of the packets not the
021504 = 10.010743
10251 * (1 / 1024) =10.0107421875
Hope that helps!

Hi,
I'm trying to synchronize a simulation in TOSSIM with an application
running a PDE model. I have timers (using Timer) firing every
10 seconds in each node to read a variable that I am updating using
the TOSSIM radio packet injection interface. From debug outputs using
sim_time()/sim_ticks_pe
Hello, I should get to the timer atm2560, you have some idea of the
direction to take?
thanks a lot,

Hello,
I am currently working on the micaZ platform using TinyOS 1.1.15. Since my application
needs to schedule certain tasks every several minutes or even hours, the maximum timer
interval is required. Timer interface uses a uint32_t type parameter, however, it says

i figured out the problem. I have fixed it and it is working perfectly!!!
There was a minor fault in wiring.

Secondly,
for the two periodic timers (with different periods), when i do getNOW(), i
get the same value. From the previous threads, i could find out that there
is only one reference timer. But does this mean that I can't have two

Even I am facing similar kind of problem. Can anyone help me please.
help appreciated.

Dear.
I made two timer and generate 10 nodes and run my application on Tossim.
But both of timers are fired at the same time even though I gave them a
different start time. and periodic fire times.
Has anybody experienced the same problem?..
Any commend will be appreciated.
Thank you
