RE: [Tinyos-help] Multichannel Adc sampling and DMA
Hi phil,
I just want to sample four channels. But to do it like you say:
acquire resource
sample 1
sample 2
sample 3
sample 4
sample 5
sample 6
release resource
For each channel i need a seperate config (4 channels = 4 configs). So do i
need one instance of the ADC interface and one of the resource interface,
and reconfigure it during runtime to sample the different channels?
Request()
Configure(1)
Sample1
Configure(2)
Sample2
Etc..
Release()
Or do i need 4 ADC instances and 4 resource instances? Or maybe 4 ADC
instances and one resource instance?
This is a bit confusing for me.
Thank you,
O.Chougna

Is the first approach only possible with the HIL ADC component

do resource arbitration. (request() , configure() , getData(),

Ah, then what you what to do is
acquire resource
sample 1

Basically, for maximum efficiency you don't want the lock (resource)
to go idle. That's why enqueueing all the requests as I showed with
the HIL is desirable. The lock won't be released until the sixth
channel is read.
Which would you recommend for 100 Hz sampling? (HIL or HAL)
You want to sample all 6 sensors at 100Hz? I'd say try using the HIL
(it's simpler) and if it can't do the job use the HAL. The one thing
to be careful of is that if you let the ADC go idle long enough, it
might power down the voltage reference, which has a 17ms warmup time.

[Tinyos-help] RSSI measuring
Hello All,
Could anybody explain how actually RSSI measured?
I mean where source code in TinyOS for reading of the RSSI.RSSI_VAL register
of the CC2420?
I found only code:
task void receiveDone_task() {
cc2420_header_t* header = getHeader( m_p_rx_buf );
cc2420_metadata_t* metadata = getMetadata( m_p_rx_buf );
uint8_t* buf = (uint8_t*)header;
uint8_t length = buf[ 0 ];
metadata-crc = buf[ length ] 7;
metadata-rssi = buf[ length - 1 ];
metadata-lqi = buf[ length ] 0x7f;
m_p_rx_buf = signal Receive.receive( m_p_rx_buf, m_p_rx_buf-data,
length );
waitForNextPacket();
}
Could you explain why buf[ length - 1 ]; means RSSI ?

Hi everyone. I'm a new user. I'm a student and I recently had some experience programming Crossbow Mica2. I worked with Gentoo Linux. Now I need to use Atmel AVR Z-link but I noticed that, in the version of TinyOS that I installed (2.0.1), there is no platform library for this device or any chip libraries for ATmega1281 and AT86RF230. There is only the chip library for ATmega128. I don't know how I can write my program for this devices if they are not supported by TinyOS. Anybody can help me?

Re: [Tinyos-help] Multichannel Adc sampling and DMA
My last question is why Msp430Adc12DMAP dont provide
Msp430Adc12MultiChannel? is this a DMA limitation?
On msp430 the combination ADC MultiChannel + DMA has not been
implemented yet (it's on my TODO list).
I also found that no constant is available to use
Msp430Adc12ClientAutoDMA_RVGC or Msp430Adc12ClientAutoDMAC in
AdcReadClient/AdcReadNowClient/AdcReadStreamClient. Is it on purpose and
why?
The HIL interfaces are platform independent and by default the HIL
clients use Msp430Adc12ClientAutoRVGC (because they don't know
whether they will need the RVG). If you are sure that you don't need
the internal reference voltage generator, you can save some code with
the switch REF_VOLT_AUTO_CONFIGURE in the header file (it uses a
Msp430Adc12ClientC on the HAL instead).
Currently MultiChannel is provided by Msp430Adc12ClientC only - I will
add the interface for
Msp430Adc12ClientAutoRVGC (if I find time next week).

Dear all,
Suppose I got two nesC files, one is client.nc, and another is server.nc,
and client.nc wanna call a function that is in server.nc.
and for example, in server.nc file, I have a command that is written as this
command result_t Foo(char *data)
{
return SUCCESS;
}
and then in client.nc file, I wanna implement it like this:
int a=0;
if( a3 )
call Foo(data)
that's all what I wanna implement, however, I don't know what has to be
included in server.nc and client.nc file,
like use something, call something, include something, I don't know what is
necessary for them.
Could anyone help me out with how to write the essence of server.nc and
client.nc please. I am new to nesC, any
suggestion would be very appreciated.
And thanks for your time reading it.

Re: [Tinyos-help] RSSI measuring
According to the datasheet, the RSSI_VALID status bit indicates when
the RSSI value is valid, meaning that the receiver has been enabled for
at least 8 symbol periods. Since receiving a packet will always be
longer than 8 symbol periods, there's no need to check. I think this
register should be checked when you're using CC2420 to sample background
noise.

2- I want Mote2 to add some filed to the received packet and then
forwards it directlly to another mote.
I want to know if it is ok to invoke sendNow() from Receive event???
...
void sendNow(){
if (!busy) {
if (call AMSend.send(0,ptr, sizeof(BlinkToRadioMsg)) == SUCCESS) {
call Leds.led2Toggle();

} }}
event message_t* Receive.receive(message_t* msg, void* payload, uint8_t len){

ptr = msg;
if (len == sizeof(BlinkToRadioMsg)) {
BlinkToRadioMsg* btrpkt = (BlinkToRadioMsg*)payload;
btrpkt-tnow= call Timer0.getNow();
sendNow();
}
return tmp;
}
I am not sure about sendNow() inside the receive event! Is it ok to
place it inside the event Receive?
what do you think??

When you want to leave in code that interacts with Leds but want to turn them off or disable them for some reason. For example, you can do some simple debug with the Leds interface wired to the LedsC component, turn off the debug by wiring to the NoLedsC component instead, and turn it back on by changing the wiring back to LedsC. ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
Re: [Tinyos-help] Fan-Out and Combine function help.
Thanks for the response Bernardo,
I included my configuration in my origional response. I understand what
the warning is telling me but I'm confused on how to fix it. The warning
claims that it has to do with my receieve interface but I only have one
instance of recieve. I'm thinking it has something to do with my AMSend
interface but I'm not sure.
Thanks

I remember having this problem. What happened to me was that this
receive interface had multiple effects in components. I don't know
exactaly how to put it, but you've wired multiple components by the
same interface, the same instance of receiver.
I had this problem when I needed to use TOSSIM with multiple
components. What I did was to connect all of the in one module and
choose to initialize the most convenient one for the node. Since two
components were wired to the same instance of the receiver interface
(although they would'n be active at the same time), whenever I
received a message, events were triggered in both components. When I
started programming the motes, I separated the components and the
warning disappeared.
So, try to check out your configurations =)

Hi sara,
I think it is better replacing the sendNow() function by a task.
This way you make the event shorter, and complete faster as recommended in

Hope that someone could help me with the following:
I would like to do the following:
1- Mote1 sends a packet every 1sec to Mote2
2- I want Mote2 to add some filed to the received packet and then
forwards it directlly to another mote.
I want to know if it is ok to invoke sendNow() from Receive event???
.
void sendNow(){

BlinkToRadioMsg* btrpkt = (BlinkToRadioMsg*)payload;
btrpkt-tnow= call Timer0.getNow();
sendNow();
}
return tmp;
}
I am not sure about sendNow() inside the receive event! Is it ok to
place it inside the event Receive?
what do you think??

It should be OK. The only thing to be careful of is the packet. You
want to make sure you do not send the buffer that you pass back to
the radio. But your code looks OK in this regard.

[Tinyos-help] Tinynode radio stack errors?
Hey folks,
So, I'm working on a Tinynode base station application. and I'm seeing some
odd behavior out of the radio. Right now, there is one repeating timer that
tries to send out three beacon messages to other motes. So, with one LED
assigned to toggle just after SendMsg.send(), and another tied to
SendMsg.sendDone(), the following happens: On the first run through,
everything works fine, I can see the packets being transmitted via a TOSBase
variant hooked up to a pc. There's about a three second delay between
SendMsg.send() and SendMsg.sendDone(). On every subsequent run through, no
packets are transmitted, and there is no delay between SendMsg.send() and
SendMsg.sendDone90, although SendMsg.sendDone() seems to be reporting a
success anyway.
Any ideas? Radio settings are below.
Thanks,

[Tinyos-help] questions on T-mote processing
Dear All, I am zay, graduate student in CSE Lehigh. I am now working on Tinyos and T-mote, but meet with some problems. I wonder whether any of you could provide me some help. I have installed the progam to the T-mote, but some errors occur when I want to issue the java listen command. My operation process is as follows. 1) export JDKROOT=/cygdrive/c/j2sdk1.4.2_12 2) export PATH=$JDKROOT/bin:$PATH The above two is to set the path for the java.exe command. 3) cd /cygdrive/c/cygwin/opt/tinyos-1.x/tools/java 4) cd net/tinyos 5) export [EMAIL PROTECTED]:tmote 6) java net.tinyos.tools.listen Then it indicates errors as Exception in thread main java.lang.NoCalssDefFoundError: net/tinyos/tools/listen. I wonder whether any of you have met with the same problem before, and do you know any reasons and solutions to this problem? Your advice would be appreciated. Thanks.

[Tinyos-help] I cannot put the micaz mote into the deep sleep by using HPLPowerManagementM
Hi all, I have searched the mail archive for info about power management. I tried to use the HPLPowerManagementM module to enable the sleep mode. I also followed the example of CountRadio to turn the radio on and off. I am able to turn the radio off and get the current down to 1.6mA in 3V when transfer nothing. However, I could not make the cpu into sleep mode even I enable HPLPowerManagementM in my code. I could not get low current such as uA level that shown in the datasheet. I wonder that if anyone successfully make cpu into deep sleep mode (uA in 3V) by using HPLPowerManagementM? Gary P - Choose the right car based on your needs. Check out Yahoo!

[Tinyos-help] Tmote, Boomerang and ext Flash
Hello,
In an effort to test the external Flash on the Tmote I wrote an
application that samples light and temperature and both store the data
in a buffer and at the same time sends the data to TOS Base. When the
buffer is full the data 256bits is committed to the ext Flash, red and
send to TOS Base as well, before the whole process repeats with a
counter moving the address space of the flash by 256bits. The problem is
that it is very unstable in that it has not written past a 7th page on
the flash and at the same time is inconsistent to where the write
process stops functioning, sometimes it all ready errors on the second
page. The code is attached and any suggestions to what might cause the
errors are appreciated.
Thanks
Mikael

[Tinyos-help] RE: PacketLink/RadioBackoff unexpected behavior
Mayur - Not sure what the difference is, since PacketLink uses PacketAcknowledgements to setup and test for acks. The PacketLink layer simply retries messages when they don't get through, and is completely optional. If you're only interested in the PacketAcknowledgement layer, then not compiling in the PacketLink functionality is the way to go, saving you memory footprint. _ From: Mayur Maheshwari [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 12, 2007 9:38 AM To: David Moss Cc: tinyos-help@millennium.berkeley.edu Subject: Re: PacketLink/RadioBackoff unexpected behavior Hi David, Thanks once again for your inputs. I understand that there is SPI contention problem. However, I installed TestPacketLink app which does not use flash at all and still the acks are not received. Moreover, when I install the TestAcks app (which uses PacketAcknowledgement) the transmitter starts receiving acknowledgements. Also, what is the advantage of using PacketLink over PacketAcknowledgements except for the application level retries/delays in the latter? Any ideas? Secondly, it is fine till the transmitting mote with small backoff is able to get its packets first to the receiver. This way the receiver should be able to send the acknowledgement first to the mote with small backoff so that it again send other packets early. Mayur, The problem with PacketLink is the fact that your acknowledgements are being dropped. The wasDelivered() command simply forwards to PacketAcknowledgements.wasAcked(). This could be caused by several things, but since you're probably using flash, that's probably the reason why. The SPI bus arbitration prevents the radio from handling acknowledgements correctly while the flash is in use. This is a known issue, and I have a fix going on my machine but don't have it ready for release. The fix involves forcing the CC2420 to hang onto the SPI bus while it is waiting for an acknowledgement. On your second issue, the backoffs should be in units of microseconds. Again, the CC2420 has to acquire the SPI bus before it can read a packet from the chip and this process, combined with actually reading bytes over SPI, could potentially last longer than the backoffs you have specified. In other words, the SPI bus will probably remain active and read both packets in simultaneously because there's not a big enough time delay between the two transmissions. Statically specifying your backoff period like you have should force mote A to get its packet through first, but you probably won't be able to detect which transmitter transmitted first unless you check both packets' source addresses. Hope that helps, -David _ From: Mayur Maheshwari [mailto: [EMAIL PROTECTED] Sent: Monday, June 11, 2007 4:29 AM To: David Moss; tinyos-help@millennium.berkeley.edu Subject: PacketLink/RadioBackoff unexpected behavior Hi David, It was nice of you that you helped me with the information on blackbook. However there seems to be problem galore ;) 1. PacketLink I tried using the PacketLink interface in one of my apps and it fails to receive the acks. Previously, I was using the PacketAcknowledgements interface and it was running absolutely fine. However, it seems that the wasDelivered(msg) event in PacketLink returns FALSE all the time. I tried testing the app TestPacketLink in \tinyos-2.x\apps\tests\cc2420\TestPacketLink and the acks were never received and the Transmitter toggled led0 every 2 secs. Again, I tested the TestAcks in \tinyos- 2.x\apps\tests\cc2420\TestAcks which uses the interface PacketAcknowledgements and this does gives positive results. 2. RadioBackoff I tested radiobackoff by having events in an app installed on two motes(A and B). I initialised the Initial Backoff times as 11 and 300 for both the motes resp. Now, I installed another app on another mote C which broadcasts and when A and B receive this broadcast they unicast their messages to C. It was expected that the message from mote B should be delayed by ~ 300 ms but I noted both the messages getting into C simultaneously. To be more clear on this aspect I recorded the events in a video and played at slower speeds but to no avail. The Leds on the mote C blink in 2~3 ms delay and I could not determine which packet went first. Would you be able to share some code in this regard. Thank you once again for all the help.

RE: [Tinyos-help] start up time
Restating your question, you would like to know two parameters: the startup time of the radio (off-on), and the time it takes to switch back and forth between rx and tx. The startup time is approximately 3 milliseconds. The tx-rx and rx-tx switching takes approximately 140 us in either direction. If you can see it, the plot below shows the radio turning on and immediately off again. The ~20 mA spike is when the radio actually reaches Rx mode, and then turns back off. The spike at the beginning is the oscillator powering up. -David _ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of roberto pagliari Sent: Monday, June 18, 2007 3:27 PM To: tinyos-help@Millennium.Berkeley.EDU Subject: [Tinyos-help] start up time hi all, does anyone know the start up time of the cc2420 radiochip ?

When I run this command, I get a command ticksPerSecond in addition to the ones listed in the tutorial. I think that this command was added after the first version of the tutorial was written. I'll update the tutorial shortly. 2) The setThreshold command, cited at the start of the tutorial section Configuring a Network, does not appear to exist in this release. Also, it is not listed in the dir(r) response cited above or in the one that I run myself. How, then do I complete the following step of the tutorial? If you set node's clear channel assessment to be at -110dBm, then nodes will never transmit, as noise and interference never drop this low. I believe this inconsistency is due to the fact that the command was removed after the tutorial was first written. I removed it because some radio chips let you set the sensitivity, so its presence would raise issues when there are conflicts between was the script and the TinyOS code specify. 3) The tutorial cites the first ten lines of the meyer-heavy.txt noise trace. However, these are not the first ten lines of the actual file in the distribution that I downloaded (from the Toilers). The first ten lines of the file I have are: -39 -98 -98 -98 -99 -98 -94 -98 -98 -98 This appears to be the same as the current CVS version of the file. If this seems incorrect, where can I find the full, correct meyer-heavy.txt noise trace? Those are the correct values. The tutorial ones are incorrect. 4) The tutorial refers to the file packets.py. This file contains the following line of code: print Delivering + msg.__str__() + to 0 at + str(t.time() + 3); This line does not run correctly for me. This is the error message: Traceback (most recent call last): File packets.py, line 46, in ? print Delivering , msg, to 0 at , str(t.time() + 3); TypeError: 'str' object is not callable However, when I change it as follows, then the code does run: print Delivering + msg.__str__() + to 0 at + (t.time() + 3); Line 46 of the latest CVS version (/tinyos-2.x/tos/lib/tossim/examples/packets.py) still seems to have this problem. What version of Python are you using? Works for me. 5) The Configuring a Network section of the tutorial has the following statement near the end: TOSSIM has two sample configuration files generated from the tool in tos/lib/tossim/topologies. The first is grid.txt . . . The second file is scatter.txt Again, this looks like the tutorial became out of sync with its underlying code base. There is no scatter.txt, and there are several grids. However, I cannot find these files in the cited directory.

[Tinyos-help] tinyOS-1.x_ADCControl_Interface
Hey All,According to my findings in the tinyos-1.x/tos/interfaces directory, and after reading the ADCControl interface I have some doubts that I expect you can help me to make me clear.I need to sample a microphone with a Sampling rate over 64Kbps, because I need to playback the audio samples, and according to the Nyquist Theorem, if I want to recover the audio transmitted I'll need to sample it at least twice of the human voice frequency.As I read from ADCCconrtol interface and ADC.h, if I use this interface and setting the ADCControl.setSamplingRate(5), which equals to T=120uS I achieve a sampling rate of Sr = (1/T)*Bits per sample = 8333.33Hz*8bits/s = 66.7Kbits/s. Acutally the ADC is 10 bits length but I drop the 2 LSB, and I get 8 bits length. I'm the MicC and I'd like to use the directly the hardware to access the Microphone, but I'm facing some problems... 1 - I can still using the MicC, but my problem is, Where to call ADCControl.setSamplingRate()?...2- am I correct with my findings?.3- someone told me that is better to use directly Harddware componet of the ADC... can I have some help from you about using the hardware?thanks in advance-antonio _ With Windows Live Hotmail, you can personalize your inbox with your favorite color. www.windowslive-hotmail.com/learnmore/personalize.html?locale=en-usocid=TXT_TAGLM_HMWL_reten_addcolor_0607___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
