Hi David,
>> 1. Identify the sensors from tos/platform/subfoler. Here I am a little
confused. I 'd like to read all native sensors on the Iris board. *Should I
be using sensors under "mts300"?*
**
Sorry, but i don't know much about Iris motes. Actually, i have been using
MicaZ (i think similar to Iris) and mts310 sensor board. So, if you have
mts310 sensor board, you should use tos/platform/mts300, if you don't have
any sensor boards, than Iris mote have sensors on it, i can advise you to
check sensor models matching with the ones in the tos/platform/xxx
directory and try them.

You should do something like this:
When read is done, do:
event void Read1.readDone(error_t result, uint16_t data) {
localSensor1.readings[Index1] = data;
}
event void Read2.readDone(error_t result, uint16_t data) {
localSensor2.readings[Index2] = data;
}
When the buffers are filled, you can send them over the radio in a task.
Don't forget the following;
localSensor1.id=TOS_NODE_ID;
localSensor2.id=TOS_NODE_ID+1;
in the boot handler.Oscilloscope java application will interpret each
message with different id seperately and plot related data.
Have you studied MultihopOscilloscope application? In that application (as i
recall) different motes have different id fields in their oscilloscope_t
structure. In your case, instead of multiple motes, you have multiple
sensors on a single mote. Same logic applies again.
Maybe you can read each sensor sequentally, when one sensor finishes
reading, read another one, ..... etc. Then, in your probable SendRadioMsg
task, switch between the filled buffers and send them over the air.
You could better play with those things :)
All the best,
