Re: [Tinyos-help] Accelerometer in MTS310CA
Hi Yes they are raw readings You can see the formula for conversion from \opt\tinyos-1.x\contrib\xbow\tools\src\xlisten\xconvert.c The function name that you should be looking for in this file is xconvert_accel. However note that the conversion involves two calibration constants calib_pos_1g and calib_neg_1g which you can determine by placing the sensor static and reverse engineering the raw value. Whether the accelerometer will serve your purpose or not can only be decided after doing some experiments Tarun On 6/10/07, Shuo Xiao [EMAIL PROTECTED] wrote: Hi, all There is a dual-axis accelerometer in sensorboard MTS310CA.

Are there some formulas in TinyOS 2 to convert the raw ADC readings to engineering units? If I measure people's movement, dual-axis accelerometer doesnot seem to be enough, what do you think?

Re: [Tinyos-help] how to get a random float number
Use rand_no = random(); This would return an integral random number between 0 to RAND_MAX. So you can divide the result by RAND_MAX to get a floating number between 0 and 1 (It won't be a real floating point random number as the set of floating numbers that you get here is limited) To generate better floating point numbers, I generate two random numbers. Scale first of them to 0-1 and second to 0- (1/RAND_MAX) . Then use second to add small amount of noise to the first number by adding them up.

The address of the mote is specified when uploading the program onto

If you are using TOSSIM, then addresses are allocated by default from 0 to N-1

event result_t Timer.fired()

if (TOS_LOCAL_ADDRESS == 0)

But during debugging with TOSSIM, the value of TOS_LOCAL_ADDRESS is always

is always 0? What are the better ways to implement? Thanks a lot.

Right...The simple path loss model:
PowerReceived = PowerTransmitted / PathLoss
where PathLoss = (4*pi*distance/Wavelength)^(path loss exponent)
won't be sufficient in all cases.
Some other exhaustive path loss model will have to be used. A lot of
such models should be already available in Communications..
That would be sufficient

2.x currently does not support this, for two reasons:
1) The exact radio metadata interfaces have not been determined yet
(i.e., should RSSI readings be hardware independent or hardware
dependent).
2) The code hasn't been written.
Since the 2.x radio model is based on RSSI, once 1) is determined, 2)
will be very easy to do. Then, you will be able to access RSSI
readings. I am not sure whether this will be ready by the first 2.0
release.
