We have an Arm 7T developer's board, and have started programming it. We're finding that clock() seems to change it's output only once a second. Yes, it's scaled to CLOCKS_PER_SEC, but one-second resolution is insufficient. Can someone confirm this for me? Is there a higher-resolution timer? Thanks. ------------------------------------------------------------------- DDDD David Kramer http://thekramers.net DK KD DKK D "Remember folks - Traffic lights timed for 35 mph DK KD are also timed for 70 mph."
