Hi all,
Is there anybody that has the same experience with me ? After the UART
in Micaz is turned off, it cannot be turned on again.
Even though the SplitControl for start and stop returns SUCCESS, I
cannot send anything to the UART.
Here's the sample of my code:

Can I have suggestions about the interface that I should implement for
MCU's internal EEPROM ?

configuration (sampling time, offset, etc) inside MCU's EEPROM (because
ATMega128 has 4096 bytes EEPROM, which I think it's more

Hi,
The criteria for choosing the RTOS is depend on your requirement.
In general, TinyOS is the correct choice if:
- You need cheap device with radio, powered by 2-AA battery 1500mA each,
and survives 6-months or even years without battery replacement.
- You need to sense physical value over
Hi,
You should view parameterized interface as array of interfaces.
Hence:
--
module A {
uses interface SendMsg[uint8_t channel];
}

should be viewed as:
--

uses interface SendMsg as SendMsg1;
uses interface SendMsg as SendMsg2;

Hi Jung,
My advice is to use individual interface, especially for small number of
interfaces. You'll reduce bug, and its easier to read.
But for the sake of learning parameterized interface in nesC, here's the
modified Blink application (taken from TOS1/apps/Blink).

If I'm not mistaken the type's definition (int, long int, etc) in NesC
is following the AVR-GCC standard. Thus, AVR-GCC refers to GCC standards
(long int = 8 bytes, int = 4 bytes).
That's why it's suggested to use uint8_t, uint16_t, etc.
Please correct me if I'm wrong.

`ncc` and `tos-ident-flags` is installed in /usr/bin by default

Under TinyOS-2.x tree, there's a directory called : support/sdk/c.

Hi,
Cast your double/float variables into nx_uint16_t/nx_uint32_t
Then re-cast it again to double/float when you receive it (actually it's
not re-cast, but read the integer value using double/float format. Something
that you can done by scanf(%f,value) ).

Hi,
I'm not sure whether TinyOS really suitable for your application.
The WSN in TinyOS is used to monitoring vast area, long period
(1min - 1day/sampling), and long term (6 months until years
without replacing the battery). 200 ms probably is very fast (though
it's not the fastest one).
Hi,
I used 2 different R (1ohm and 25ohm) with large delay between
sending/receiving packets (around 30s). Since there are spikes
(even in the sleep mode), I use oscilloscope's average value.
Thus, to get the whole current consumption, I measured the sleeping
current first (using 25ohm).
Hi,
What version of TinyOS that you use ?
I've done the same thing in T2.0.1, and it worked fine.
Here's how I test it :
1) Put node 0 and node 2 out of range
2) Put node 1 in the middle (in range for node 0 and node 2)
3) Test multihop by turn on/off node 1

Hi,
I'm not sure about your problem. But I think you should check the

Also, have you change the data structure inside your mote's
firmware when you change the HelloMsg struct ?

Hi,
Use one-shot timer to do it.
Eg :

}
event Timer.fired()
{
call Led.led0Toggle();

Hi,
There's a script called tos-locate-jre in /usr/bin.
Try to run it using : #tos-locate-jre --jni
It should return : $yourjavahome/jre/lib/i386
Otherwise you have to modify the script to return that value.
I'm running Ubuntu, and I've modified that script (but I forgot which line).

I think there's something wrong with your hardware (or your PC's
