Hi all,I want to get a time which resolution should be microsecond on Tmote Sky. In my host computer and another platform E100 USRP I can use the function of gettimeofday(). But through mspgcc-4.5.3, the gettimeofday() is not accepted. Even after I added the time.h from my host computer's include/sys directory into /usr/local/msp430/include/sys/, it shows "undefined reference to 'gettimeofday'. I checked the new added time.h, it uses an external function definition, which means it will rely on an external function do implement the practical function. But it seems this real external function is not existing in mspgcc. I wrote the function as http://svn.cod3r.com/a52codec/trunk/liba52/src/gettimeofday.c directly, but the ftime() function in the invoked timeb.h is still an external function. I guess maybe I haven't install some necessary lib. I checked I have no gnulib, I don't know does it matter? I have spent too much time on that. Does anybody know how to get a relatively precise resolution time on Tmote Sky? Thanks in advance!
Sincerely, Zhonghua
