    Default Question about Melanie's Olympic Timer

    Hello,

    I want to use Melanie's Olympic Timer, to add to my project. I am not familiar with interrupt, so my question is: Would my 1000 line code have an impact with the timer of her clock. Would it be easier to take a timer chip like the DS1307 to count externally? I just need to user a timer as a stopwatch.
    thanks

    The Olympic Timer uses ON INTERRUPT. So it's very likely your program will interfere with the timing.

    The Elapsed Timer Demo uses ASM interrupts and may keep better time.
    But it may also affect time dependant statements like SEROUT and PAUSE.

    A DS1307 will have neither of those problems.
