[Tinyos-help] Alarm32khz32C on Iris Mote

[Janos Sallai]

Sarfraz,

 

There is no timer configured for 32khz on the iris platform. You have
the following options:

 

1.       Use CounterMicro32C/AlarmMicro32C if it fits your application's
needs.

 

2.       Reconfigure Timer 3 to 32kHz, and create an alarm on top of it.

 

Note that all of these timers/counters stop when the mote sleeps. You
can prevent this by implementing McuPowerOverride in your app. Also,
please note that the frequencies provided by these timers are not
exactly 32kHz or 1MHz, but 28800Hz and 921600Hz, respectively (prescaked
MCU clock).

Hello everyone,

I am trying to use Alarm32khz32C in an application that I intend to use
on an iris mote. However, when I compile with "make iris" I get the
following error

In component `Counter32khz32C':
/home/mnawaz/tinyos-2.x/tos/platforms/mica/Counter32khz32C.nc:34: no
match

I am using the tinyos-2.x checked out of CVS and I can compile and
install other applications under apps for Iris. Any help or pointers
would be much appreciated.

Regards
