Question:



The Delay() function is suposed to be accurate down to 1 ms,
however, I am getting errors within 1/18th sec. when I use it.

Answer:



The delay function relies on the real-time-clock, which, by 
default, clicks at 18 hz (cycles per second.)  In order to get a 1 ms
accuracy, the clock has to be set to 100hz or greater.
