Hi,
I am using TinyOS1.x on mica2 motes. I would like to measure the energy
consumed by my TinyOS application which uses external serial flash on mica2
motes. I turned to Avrora and was able to get energy values for CPU, Leds and
Radio. However, the energy values for external flash is way off the mark. I
tried to modify the energy instrumentation in sim/platform/ExternalFlash.java.
It turns out the implementation of the device emulation is buggy. In
particular, the amount of time the device should keep its status as busy is not
correctly implemented and hence, energy values are incorrect. I tried the
Avrora mailing list for the last two weeks but haven't received any response
from the developers. I would like to fix the bug in Avrora but I don't have
much experience developing device driver code.
So, here are some basic questions. I need to know how TinyOS drives the device
when it writes into the External Flash. What Tinyos files should I look at? Is
there a manual to operating (reading/writing) into Serial flash used in mica2
motes? Any pointers will be appreciated!
Thanks,
Mac
