Re: Re to Re: [Tinyos-help] telosb and mica2
Maala, The mica2 and the telosb are not compatible because their radios work at different frequencies. The telosb radio (CC2420) works in the 2.4 GHz band and the mica2 (with the CC1000 radio) works at either 433, 868 or 916 MHz depending on the type you have. The telosb motes are however compatible with micaz motes if that's any help you.

[Tinyos-help] Network types
Hi, I was wondering what the use of nx_uint8_t and nx_int8_t is, since network types are here to use the proper byte order. Is it just to provide the full set of network types ? Also, does using these types when not necessary induce adding useless instructions ? I wonder this because I use nx_uint8_t * pointers in my code to indicate that I manipulate data in packets, while I could just use uint8_t * (if my assumption that nx8 has no use is correct). Thanks for your explanations, Romain ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
R: R: [Tinyos-help] 2kHz on MDA300
Dear Mr Alessandro Balvis, I would like to ask you, if it is possible, to provide me with more information on how you achieved to collect data with MDA300 with 1000Hz sampling frequency? What variables have you actually modified and at what value have you set them? We try to increase the sampling frequency but we can only get data at around 150Hz. In particular, I have set in SamplerM.nc: TIME_SCALE =1 MAX_SAMPLERECORDS = 1 (I collect only the reading from ADC0) In my program I have set: Timer_rate = 3; ANALOG_SAMPLING_TIME 2 (Note that these are the smallest values with which I can collect packets) Also, I fill a packet of 26 samples and then send them ( Do you know a way to increase the number of samples in a packet?. I have changed the message length but when I increase the samples to 27 I cannot get packets at the base.) Any help would be really appreciable.

[Tinyos-help] Damaged Mote
I've never had a damaged mote before, so I want to confirm with someone. It is a Mica2 Mote. TinyOS 1.15; Cygwin/Windows XP. I'm using the MIB500. When I send uisp commands on this particular mote I get: pulse An error has occurred druing the AVR initialization. * Target status: Vender Code= 0xff, Part Family = 0xff, Part Number = 0xff Probably the wiring is incorrect or target might be `damaged'. All the other motes work fine except for occasional read errors, which have been anything from gremlins that require an erase and a few tries to get it to catch to wiggling the cable and unplugging the reader to get it to work again. -- The difference between the right word and the almost right word is really a large matter- it's the difference between a lightning bug and the lightning. -Twain ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
[Tinyos-help] How to set the digital output pins of mda320??
Hello I have just arrived to the list. I'm working with the adquisition card mda320 of crossbow. I'd like to know how set the value of the digital output pins... the software given with the moteworks, named XMDA320.nc and XMDA320M.nc is able to read these bits, but I am really interesting in write them. I have checked the SamplerM.nc module, and I have seen that the set_digital_output method is empty... looks like you should use the Dio component, and I tried to include in XMDA320, but I did not work. I don't know if the solution is to fill the set_digital_output in SamplerM but I don't know how to compile the tinyos libraries when the changes are done. Can someone help me?

RE: [Tinyos-help] LabView Crossbow Drivers
These LabVIEW drivers provide middleware functionality by parsing/converting raw packets coming over serial port. You still have to write client tier app code to display this data in the form of graphs, data grid etc. For LabVIEW users, this saves the time of having to deal with the data at byte level.

[Tinyos-help] Call for Participation: TinyOS Technology Exchange
The Fourth International TinyOS Technology Exchange (TTX4) will be held at MIT on Saturday, April 28th. http://tinyos.stanford.edu/ttx/2007/ The TTX is a yearly venue where developers, users, and companies involved in low-power wireless sensing get together to talk about recent developments and future directions. The focus of this year's meeting is the formation of the TinyOS Alliance, a non-profit organization designed to provide a structure to better support collaboration in achieving technical excellence. The TinyOS Alliance Steering Committee encourages anyone who is interested in, using, exploring or advancing TinyOS-based technologies to attend. There will be reports from the six existing TinyOS working groups, a session on new working group formation, and a series of interesting panels that bring industry and academia together to discuss the important challenges ahead. The focus of the event is ultimately on the community, its innovations, and its work, and so there are three ways to participate and share your accomplishments: 1) The contributions session. The session will begin with the contribution czars, Kevin Klues and Martin Leopold, talk about how you can bring your code into TinyOS for others to easily download, use, and extend. The majority of the session will be two-slide, three- minute presentations from members of the community describing work they've done and which others can use. All you need to do is bring your slides and get up to the microphone. Contributions to any version of TinyOS (pre-1.0, 1.0, 1.1, 2.0) are welcome. 2) The demo session. If you've built a new application, a new platform, have new technology or new research ideas that you want to demonstrate to the TinyOS community, this is a great forum for doing so. To register a demo, please email the demo chair, Lewis Girod (girod at nms.csail.mit.edu). 3) The working group formation session. Is there an area that you think bringing interested parties together to collaborate would help advance research and technology? This session provides an opportunity to present proposals for new working groups to the community, in order to gather support, interest, and momentum. The Steering Committee has recognized two working groups it thinks would be beneficial to form; if you have an idea, just have a few slides to let people know.[1] In addition to all of these sessions, the TTX4 will have the next release of TinyOS 2.0 (2.0.1), which will include a large number of advancements, including robust low-power operation for micaz and telos-family nodes, improved sensor board support, a beta version of network reprogramming, and a new way to very easily install TinyOS. The event is free for students, and has a $50 registration fee for non-students; this fee is to cover costs for the coffee breaks and lunch which will be served. On behalf of the TinyOS Steering Committee, the local organizer Matt Welsh, and the demo chair Lewis Girod, we all look forward to seeing you there.

just to beat the twitching horse...
here means bit-wise AND,
so if bit 0 in value is a 1 the value1 test is true
It would have been nice to have a space before the number (v 1)
and even put the number in hex so it's a bit more obvious.
It does look like 4 is some kind of secret handshake thing...

[Tinyos-help] Error in Readings
Hi,
I am using tmote sky and trying to measure pressure using a pressure sensor. I
am reading the V+ and V- from sensor using two adc channels. The problem is
that if I do subtraction in the program I am getting different values that is
in one case I am receiving two values of both channels and then I am doing
subtraction in Matlab while in the other case I am subtracting the two channels
in the code and receiving only the difference.The difference in values is 4-5
units like
1590.0 8.0
1591.0 8.0
1592.0 8.0
1593.0 11.0
1594.0 8.0
1595.0 9.0
1596.0 8.0
1597.0 8.0
Two channel case:
Ch1
4680.0 3951.0
4681.0 3950.0
4682.0 3951.0
4683.0 3952.0
4684.0 3950.0
4685.0 3953.0
Ch2:
4680.0 3939.0
4681.0 3939.0
4682.0 3938.0
4683.0 3940.0
4684.0 3941.0
4685.0 3939.0
Differnce:

[Tinyos-help] Do I need use Hamamatsu inferface for light sensor - -help me
Hi all
Hi all,
I m a Newbie working on telosb motes of Crossbow. Using TinyOS1.x
I am working on a task how to detect the light sensor and produce a beep sound
if there is a significant change in the light. Do I need use Hamamatsu
inferface for detecting light sensor. I m using sounder interface to produce
beep sound. Is this correct ..
module SenseM {
provides {
interface StdControl;
}
uses {
interface Timer;
interface ADC;
interface StdControl as ADCControl;
interface StdControl as SounderControl;
interface Leds;
}
}
implementation {
// declare module static variables here
/**
* Module scoped method. Displays the lowest 3 bits to the LEDs,
* with RED being the most signficant and YELLOW being the least significant.
*
* @return returns codeSUCCESS/code
**/
// display is module static function
result_t display(uint16_t value)
{
if (value 1) call Leds.yellowOn();
else call Leds.yellowOff();
if (value 2) call Leds.greenOn();
else call Leds.greenOff();
if (value 4) call Leds.redOn();
else call Leds.redOff();
return SUCCESS;
}
/**

**/
// implement StdControl interface
command result_t StdControl.init() {
return call Leds.init();
}
/**

command result_t StdControl.start() {
return call Timer.start(TIMER_REPEAT, 300);
}
/**

*

**/
command result_t StdControl.stop() {
return call Timer.stop();
}
/**
* Read sensor data in response to the codeTimer.fired/code event.
*
* @return The result of calling ADC.getData().
**/
event result_t Timer.fired() {

Please help me out

[Tinyos-help] Adding new fields to tinyos header (re-framed question)
Hi, I have to add new fields to the tinyos header for telos motes in tinyos-1.x. When I try to modify TOS_Msg in AM.h (for telos motes), I can only go up to adding 2 more bytes to the default header. If I try to add any more fields, sending msg encounters failure. The header size is calculated in AM.h itself, so I don't understand why I cannot add more fields to the header. Is there some max header size defined for CC2420 somehwere which I could increase? thanks, Abhishek -- All you need in life is ignorance and confidence, and then success is sure. ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
