Update: upon a couple more hours' testing, I found that the above command
actually prevents the bot from turning at all. It will only turn if I pass at
least RESET_BLOCK_COUNT for the last parameter (of course other combinations
that include resetting the block count, e.g. RESET_ALL, also work).
Whew, that was a couple of hours wasted! Lesson learned, but I still don't seem
to be getting good tacho counts, and I'm still curious whether there is a
standard NXC loop for following a line while measuring distance travelled.
Thanks,
