[Tinyos-help] (no subject)
Hi Miklos, I'm just wondering if you could help me please. I've tried to implement a similar scenario to the TestFtsp application where three TestFtsp motes should send to the base station the local rather than the global reception timestamps of messages broadcast by a dedicated beacon mote programmed with RadioCountToLeds at periodic intervals (say each 1, 2 and 4 seconds). I found that the measured intervals (the difference between tni and tni+1 where tni and tni+1 represent, for example, local reception timestamps of beacon 'i' and beacon 'i+1' according to the local time of mote n) are almost the same for the three TestFtsp motes for the same beacons (i.e. raw data of the attached table). However, by comparing the measured intervals of the same TestFtsp mote (i.e. column data of the attached table) I'll get noticeable differences. In fact, I was expecting the opposite. Could you let me know whether what I got is wrong or not? and what is the reason for such results? BTW, I'm using tinyos 2.x and micaz platform and I'm not going here to test whether the TestFtsp motes are synchronized or not. Thanks in advance for any help.

[Tinyos-help] Timestamping the start and the end of a sampling process
Dear all, After posting my problem to TinyOs mailing list and searching a lot in TinyOs-help and following some hints, I still cannot find a solution to my problem which is described below: I'm using tinyos-2.x and three micaz platforms equipped with MTS310 sensor board and once they receive a start sample command from BS, they will start sample the mic sensor immediately. Each mote timestamps the start and the end of the sampling process in order to compute the sample interval. My question is: Why I always do receive different lengths of sample intervals (for example, with a STDEV of 601.1724757, 325.9728201 and 472.9102405 for the three motes)? First I was using CounterMicro32C component and Counter.get() command to timestamp the start and the end of the sampling process and then I tried to use CounterToLocalTime component as well. But in both cases I still have the same problem. So, please share with me this problem and let me know your suggestions ASAP. Any hint might be useful for me and take me a step forward. Thanks in advance, Omar ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
[Tinyos-help] receiving different sample intervals
Hi All, I'm using tinyos-2.x and micaz platform and I'm having problems with my microphone sample application, the thing is simple, three motes are waiting for receiving a start sample command from BS and once they receive it they will start immediately the sampling process. Each mote timestamps the start and the end of this process in order to compute the sample interval. The problem is that theoretical the three intervals should be equal because they use the same buffer length and sample at 4kHz, but I always got different sample intervals (with a STDEV of 601.1724757, 325.9728201 and 472.9102405 for the three motes). I'm using CounterMicro32C component and Counter.get() command to timestamp the events. Could anyone please suggest any idea about how can I improve these results. Thanks in advance, Omar ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
[Tinyos-help] Why my received signals incoherent?
Hi all, I'm using three sensor nodes (MICAz + MTS310), positioned at the same distance from a sound source, to sample a click signal at 4kHz.The sensor nodes start sampling simultaneously once they receive a start command from a base station and a buffer is used to hold 1200 samples in each sensor node. When the buffer is full, each sensor node will start sending their sampled data to the base station which will forward them to a PC. They send their own sampled data serially to the base station. When I plot the received signals I expected to get coherent signals but this was not the case although the experiments were conducted in the same environment and under the same conditions. So, what could be the reasons for such incoherent signals? I appreciate any help in advance, Omar ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
Re: [Tinyos-help] continuous sampling of mic
Hi Miklos,
Thanks for your response. Yes, I tried to use Atm128FastAdc library and
MicReadStreamTest application. However, as you said it works only for IRIS and
unfortunately not for MICAZ, but the Soundlocalizer works fine for MICAZ. So,
is it possible to modify the soundlocalizer example so that it can sample the
mic sensor continuously?
I would really appreciate your help.
Thanks again,
Omar

[Tinyos-help] continuous sampling of mic
Hi all,
I would really appreciate if someone can reply and guide me with this problem.
Is it possible to modify the soundlocalizer example explained in Tinyos
programming book, chapter 13 so that it can sample the mic sensor continuously?
In fact, I tried to do it by putting the "Atm128AdcSingle.getData" command
inside a for loop and each time the event "Atm128AdcSingle.dataReady" is
signalled, the data will be added to a buffer as shown in the code below.
However, it does not work as I expected. It seems to be that, although I can
see that the "Atm128AdcSingle.getData" command is executed several times
depends on the buffer size, the event "Atm128AdcSingle.dataReady" is signalled
only once (I don't know why?).
Pleas correct me if what I did is wrong.
void Cont_Sample() {
for(i = 0; i < BUFFER_SIZE; ++i)
call Atm128AdcSingle.getData(call MicAdcChannel.getChannel(),
ATM128_ADC_VREF_OFF, FALSE,
ATM128_ADC_PRESCALE_32);
printf("Here is a ith value: %d\n", i);
printfflush();
}
/
async event void Atm128AdcSingle.dataReady(uint16_t data, bool precise) {
Add_DataToBuffer(data);
}
void Add_DataToBuffer(uint16_t Mic_data){
MicRead[i] = Mic_data;
if (i == BUFFER_SIZE)
{
printf("last iteration value: %x\n", i);
printfflush();
post stopMicrophone();
}
}
BTW: I am using Tinyos-2.x, Micaz and mts300.
I would be very grateful if someone can help.

[Tinyos-help] TinyOS-2.x and Sampling rate
Hi all, Currently I am trying to implement a simple code using nesC language and TinyOS-2.x so that a sensor node will be able to capture an acoustic signal generated by a PC speaker, for instance a sine wave or a gunshot signal, in order to know what is the maximum sampling frequency that MICAz mote can achieve. This code is installed on a sensor node which sends the signal captured to the base station. However, I only can achieve maximum sampling frequencies in the range of 200Hz and 750Hz using Read interface and ReadStream interface respectively. But... In the literature, it was reported that, in tinyos-1.x, the MICA components can normally sample at a frequency up to 200 Hz (in real time transfer mode i.e. sampling and sending), while in the ADC's free running mode (i.e. turning off the wireless radio of the MICA components while sampling) the highest sampling rate using these components can reach 17.723 KHz. After I read the TinyOS Programming book, I decided to use TinyOS-2.x instead of TinyOS-1.x in my project because of two reasons: 1- it is expected that the sampling frequency can be easily increased since TinyOS-2.x supports in addition to a millisecond timer a microsecond timer which could be used to improve the sampling rate. 2- It supports the ReadStream Interface which is equivalent to the ADC's free running mode. But, as I tried to use the microsecond timer in my code, I surprised that this type of timer is actually unknown for the compiler. Also, in ReadStream mode I only can reach 750 Hz as a maximum sampling rate by setting timer.startperiodic(1300) (below this value the senor node does not send any data). So, my questions are: 1- Is it right that the microsecond timer still not fully supported by the MICA components? 2- Which commands that can be used to set the sampling rate in the ReadStream interface? Or is there an technique that can be used to achieve high sampling rates? I am looking forward to hear from you and I appreciate in advance any help.

[Tinyos-help] (Sample and save) instead of (sample and send)
Dear All, I would be appreciated, in advance, if anyone could help? I'm trying to sample acoustic signals using MICAz, MTS310 sensor board and TinyOs 2. under MoteWorks environment. I have succeed in some how to sample these signals in a way that the code, after each individual sampling process, sends the sampled data to the PC where the data will be saved and processed offline. In other words, it samples and sends immediately the sampled data. What I'm looking for is to know: is it possible first to sample and save then to send all sampled data after finishing the sampling process to the base station? If yes, how?

[Tinyos-help] Handshake routine
Dear Michael, I am currently using MTS310 sensor board and MICAz Motes in order to implement a single hop wireless network. I have used one of the tutorial examples which samples for example only the light sensor on a sensor board, packetizes, and sends the data back to the base station directly through first the serial port (UART) and second over Mote radio. The experimental scenario was as follows: One of motes was used as a sensor node to sense the light and the second one was programmed with TOSbase code and was plugged into MIB520 gateway to monitor the RF packet contents by displaying them using XSniffer on PC. I would be appreciated if you could help me to understand the handshake routine between the sensor node and the other Mote.
