Hi everybody,
As a student, this semestr I took a part in really interesting project
concerning adaptation of sensor networks in next generation networks.
After that my love to sensors begun :)
Today I start to work in one of the institutes in Berlin. I need to
present for my bosses which one of
Hello,
The other day I needed to use another computer to program a few Z1 and I
didn't have the laptop I usually use. I didn't want to change the hdd from
the netbook I was going to use, so I made a ubuntu 10.04 liveUSB with
TinyOS.
The image was made to be able to program Z1 motes from Zolertia
Hello everyone,
I'm trying to understand the relationship between ROM and RAM .hex file
generated in the build.
It has been said here that:
In words few ROM includes the code and initialized data RAM and includes
BOTH initialized and uninitialized data (note the stack That Is Not
Included).
I've been trying over and over but I'm only getting:
serial@/dev/ttyUSB0:57600: resynchronising
and then that it is sending several packages, but receiving none.
Sending packet 0
Sending packet 1
Sending packet 2
Sending packet 3
Sending packet 4
(...)
Any ideas?

I use the same thin , as I told before I tried a couple of ways since I
thought maybe it is not possible to communicate directly from windows to
mote.
this code mentioned by you works pretty well on my Linux version of
application, but on Windows version it doesn't open PrintStreamMessanger.err
Hi Ricardo,
The HEX file is a text file. Every byte of the binary is written as two
characters (human readable hex values). In addition, there are
addresses, checksums and other programming or control information.
If you don't assign any value to a variable declaration, that variable
will get
Thanks for the reply.
Let me get this straight, the actual occupied memory is provided as a value
for the ROM (13800). The flash memory contains the .hex file, which is then
decomposed into the ROM and RAM.
Is my understanding correct?
Regards,

Hi,
Could you explain me what CFLAG += CC2420_DEF_RFPOWER=4 stands for?
It's the cc2420 radio-chip transmission power, isn't it?
Could you tell me which RFPOWER values are available and what is the
translation in terms of dBm?
Do you know if a similar flag is available for IRIS and where I
Hi Ricardo,
I'm not sure I understand your explanation. Also, I'm not entirely sure
how this works on the microcontroller. Essentially, a program consists
of a number of sections. One section is the actual program code (i.e.,
the instructions in binary form), and for the programs generated by

Right.

Please refer to the CC2420 datasheet:
I'm not familiar with an O'scope program that sends
messages from the PC to the mote, so I don't know
what is Sending Packet N...
I would try to find a demo app that sends periodic
messages without needing to be told (so the PC doesn't
have to send anything back...). The TOS1.x O'scope and
Sense
My understanding of global variables is that anything
declared outside of a function definition is allocated
in the heap at link time, and the final size of that
heap is what is reported as RAM usage. All variables
inside functions (that are not labeled static in real C)
are just names for stack
I am having problem precisely reading in a pulse-width signal on a
telosb node.
This code runs, but I think errors are coming from non-deterministic
execution of events between this and other events in the code.

uint16_t time;

I tried installing tinyos onto a different computer than the one I was
originally using but now I keep getting an error: make: ***[program]
Error 57. This only occurs when I try installing the program to a
mote. If just build the program then I get no errors. Does this mean

Hi,
I am interested in the area of developing routing protocols for WSN.
I would like to know,
Is it possible to implement routing protocols for WSN?
Has TinyOS got any built in routing protocols like LEACH, HEED, so that I
can perform comparative study of my routing protocol.

I want to develop an application which will run over BLIP UDP socket on the
