Re: [Tinyos-help] Help with Timer
Yes thats ther very reason why Timer is a parametrized interface. You can specify upto 256 unique timers with Timer. Every time a module uses a timer, make sure to write.Timer -> TimerC.Timer[unique("Timer")]; in the configuration
The string "Timer" should be the same for all your timers only then can you be sure that you have generated unque timers. Refer Tutorial 2 for more on this.If you check back a few days on this list, somebody had talked about a special module to be used for sleeping and waking the node up.

[Tinyos-help] 1.1.0 to 1.1.15 problems
Hi, Are there recommended packages to install moving from the initial release to the snapshot? I’ve tried just extracting it using the rpm, but it throws a bunch of errors on the Deluge package, and I’ll be working with Telos motes, so I need to have the mspgcc stuff, and what else? I’ve tried using the build-mspgcc script that I found buried down in tools/src/ but it seems that a lot of sites it references are dead now, or not working. I can’t find any kind of documentation on the site as far as what packages are required short of trying to use the packages listed for 2.0 and I’m not sure if that’s exactly intended. I’m running on FC4, so I guess I missed the “wizard” in 1.11? I didn’t see anything indicating a wizard, which is mentioned off of the download page. If you really need the error log, let me know. It’s ridiculously long, and most of it is from the Deluge package trying to be built. I’m just trying to figure out everything that needs to be added since a simple upgrade did not work, and I have to do this on two more computers within the week.

[Tinyos-help] A question TMote Sky's UART0 and radio control
I have successfully programed Tmote Sky to transmit/receive data from UART0. However, my key concern is: UART0 shares bus with Radio; so, when I read large number of data (say 130 bytes), will the radio receive and buffer data from other motes and trigger ReceiveMsg after UART0 release resource? Or the radio will not buffer by itself hence message is lost, then the sender need re-send the message late on? Which hyperthesis is correct? If the first hyperthesis is not correct, are there any other digital interface to use in Tmote-Sky (which does not share bus with radio)?

RE: [Tinyos-help] tmote batteries lifetime
6 days sounds about right. When the radio is turned on and simply listening, it is consuming an average of 18.2+ mA - your 18.8 mA sounds accurate. I measured it to be about 437.4 mAh/day. With 1500 mAh batteries and those measurements, you're looking at about 3-4 days lifetime. Duty cycle the radio and you'll get many more days. At 0.23% duty cycle with a cc2420 radio duty cycle period of 10 seconds, the lifetime of a tmote should be about 300+ days at 1500 mAh. Keep in mind that batteries are rarely what they say they are - 1500 mAh is the minimum guaranteed by the manufacturer. Many batteries can potentially last much longer than what they're rated, especially depending on the environment and type of battery. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Wednesday, May 24, 2006 9:27 PM To: tinyos-help@Millennium.Berkeley.EDU Subject: [Tinyos-help] tmote batteries lifetime I have one doubt about tmote batteries duration.

My problem now is to know if it is possible to add code to this C file or an

funcionalities written in C and how. The target is to reuse code written in C
from old projects.
Do you have any experience similar to this? Do you know somebody that can help
me in this matter?
Either:
- include the code in a module (module bodies are essentially C code)
- or, just compile your C code as usual, and link it in at compile-time, i.e.:
foo.h:
void myfunction(int myarg);
foo.c:
void myfunction(int myarg) { do something fun }
gloop.nc: (wants to use the stuff in foo)
includes foo;
module gloop { whatever }
implementation {
... myfunction(23); ...
}
compiling it all:
cc -c foo.c
ncc .nc foo.o
Integrating this with the TinyOS makefile system is left as an
exercise to the reader (this is one of the drawbacks of the
super-duper makefile system...)
