Hi,
I have this problem too.
If you check the schematics in the TMote Sky datasheet, you will see that
the negative reference voltage pin is grounded.
So you can measure only between 0 and any value.

If you use TinyOS 2.0.1, you need to update your script to be
compliant with the new radio model of tossim. It is described in the
tutorial.
Also, you didn't set the noise of your 4th node.
Hope it helps,

Hi,
Osciloscope app, samples and sends the sensor via UART, while
OsciloscopeRF app samples and sends via radio. To use Osciloscope app,
just connect to PC. To use OscilloscopeRF, program a mote with TOSBase
as a abasestation and connect this basestation mote to PC.

hi
i have read the new tutorial (Lesson 11) about Tossim, but i meet a problem.
It seems that event Timer.fired() does't work.(i can see the Boot,but i
can't seeRadioCountToLedsC: as expected in the RadioCountToLeds)
by the way, i use the tinyos2.0.1
Any help is appreciate!

If you read in the MSP430x161x data sheet, in the section 12-bit ADC,
external reference, the minimum allowable voltage into VeREF- is 0V.

Antonio,
The settings for an ADC port are defined in MSP430ADC12.h header file.
As
On a tmote, the parameters to an adc port can be bound as follows:
call ADC.bind(ADC12_SETTINGS(INPUT_CHANNEL_A0,
REFERENCE_VREFplus_AVss,
SAMPLE_HOLD_4_CYCLES,
SHT_SOURCE_ADC12OSC,
Thank you Cory,
your reply explain why pin VeREF connect to ground.
A greeting,

Hi all,
We are working with Oscilloscope and OscilloscopeRF apps. We would like to
know how can we receive an OscopeMsg via radio. The Oscilloscope app only
receives from sensor, but we need send from a mote with OscilloscopeRF and
receive via radio at the base mote to pass the info by the
Hi all,
I want to enter some values when my program starts running like Press 1 for
this, Press 2 for this .
Is it possible for the user to make such type of enteries and change the
variable values at run time?
Thanks in advance for your time,
Regards,
Fahad Jan

The VeREF+ is connected to ground as well. I think theres no way to convert
negative voltage with ADC channel.

Hi all,
I would like to test Deluge applications on my Micaz motes. I have been
able to inject new images inside my motes, but unable to reboot them.
I have tried to reboot the mote directly on the serial-based programming
board (mib510), but it fails too.
My current tinyos version is 1.1.15.
Hi all.
We are working on a project. We want to build an Environment Monitoring
application. This application allows each mote in the wireless sensor network
to sense several environment parameters such as temperature, light capacity,
humidity, and sound. The sensed data are to be
read the doc/tutorial and look at the SenseToRfm and OscilloscopeRF demo apps.

Hello!
Maybe my question will not belong to the tiny-os, but i hope that someone
could help me with my problem...
I have a problem, that i have to connect a gateway with a database to get
data from the gateway, which comes from a sensor network. The data are in
xml format. I make it at first
Hi,
I just read lesson 5 of toturial of TinyOs2.0. I am still confused on where

the accelation of X and Y axis. Which component in TinyOs 2 can be used? Can
VoltageC in '/tos/platforms/mica2' get the output of
My apologies, I found the solution in the archives. Editing the atm128_sim.h

What? the 25 channels in MakeXbowlocal aren't enough?
Probably the CC1000 spec sheet is the place to look.
I have no idea where I found mine but it's labeled:
Chipcon AS SmartRF CC1000 Datasheet (rev. 2.2) 2004-04-22
I think it's basically continuously tunable...

Dear all,
I am tryin to build an application wherein it is required to collect 8bit data

the oscilloscope application be modified in order to do the same. I wont need
