Hello everyone,
I got radio problem when use the XSensorMTS400. I can only get data
from mote by plugging the mote to mib510 in UART. But it doesn't work
when I test with one TOSBase in mib510 and the other mote send data by
radio.
And I check the frequency carefully. There is no problem. I run
i have to build a project in tinyos and i must use power tossim to evaluate the life time of the sensor network but i must enter my own valuefor estimation for example in state IDLE i must use 140.4 mjso i must put this value in power tossim
please can any one help me i will be very
Hi all,
I would like to ask all of you about
questions related to integrating new type of sensors into micaZ mote
platform.
This new type of sensors provides a serial data output.
So is it possible to connect this sensor to micaZ mote for taking
data, pre-process and send to the PC for
Hi Aung,
You can connect it into UART 1. The only drawback is, the tx/rx pins are
also used for external flash access and there's no built-in arbitration. So
you should take care of that if using your sensor and flash in the same
application.

I re-run the tinyviz with CntToLeds and just 1 mote.
this is the end of message part in the cygwin shell:
.net.tinyos.packet.PhoenixSource.run(PhoenixSource.java:167)
SimComm: TossimInitEvent received (1 motes)...
initializing system.
SimComm: Pausing system for TossimInitEvent
What means?
Hi Hannes, All,
Thanks for that. I have already tried that and it works to some extent.
The problem is that the node will only pick up the odd packet where the crc
is not correct (although this shows that it will pick up a failed crc). The
other times it just doesn't seem to pick up
Hi I am working on the MICA2 motes on the topic of localization. I had two questions1. In nesC, how do i change the power of the radio. Tha manual says that appropriate values need to be written to register 0x0B. Do i need to use assembly?
2. Can I program the mote to transmit at a particular
Hi Ian.I am not too clear what is TDMA protocol (is it Ttime division multiple access..how does it work)
We are using the GenericComm component for radio communication. I had specifically two questions
1. As per your reply, TinyOs has some sort of an internal queue for the
send operation. I can
Josh,
You can steal the conversion C code from
contrib/xbow/tools/src/xlisten/xconvert.c.
That should provide you with all of the proper conversion algorithms.

Hi Andrew,
I am looking to use the serial port to talk with another device.
What I was thinking was that I could cut the UART1RX and UART1TX lines
before they go to the I/O buffer and reroute them from the
MSP430. The only problem is that I am not sure that the bsl does
not send signals over

I am using the tmote sky. I wish to allow the motes to receive packets that

Why is the reset sequence recognition chip powered off the
batteries? It seems that this chip is only usable when the mote
is powered off the usb.
Thanks,

Hi all,
I'm trying to connect a CMUCam2 with a MicaZ via Uart. Since the camera
can't understand TOSMsg packets i need to change commands byte-to-byte.
A attached a TTL Serial port into MicaZ expansion Uart pins (27 and
28). The comunication uses Micaz default settings 57.6 Kb, 8 bits no

mica{2,z}, It's been a while since I worked it out but I think the
MOSI/MISO pins are not necessary.
Hope this bears some relevance to the 'Dot...

I'm not sure that the channels are mutually exclusive, those next to

There have been massive discussions of integrating sensors to the
mote serial port. Search back through the help list over the last
few months.

Just to be sure...the camera is really TTL level and not RS-232 right?
And you do know for certain that it is sending something to the mote?
I interpret your comunicate via RS-232 (MIB-510) using minicom to
mean that comm between the mote and the host over over the serial
line works fine. Are
I'm not sure MicaHWVerify works with the 'Z's I haven't tried it.
If you are getting radio comm from other programs you don't need
to try it either. Have not actually used the HFS program but the
mica systems are very similar so I would expect it to work ok.
One thing to try with your '2's...if

I'm trying to order messages from nodes in the network.
I want to order messages by comparing timestamp field in the message.
For this purpose, I think I need to make system to be time synchronized first.
