    See Melanie's excellent post here

    http://list.picbasic.com/forum/messages/3064/3607.html?

    it is for a different processor but converting to the 877a should be straight forward. Reply if you need more

    I Love the way you think Melanie . . .
    In a battery operated piece of equipment we need to detect when the
    batteries are getting low, so in turn we can switch on a 'Battery Low' LED
    to help flatten whats left of the battery even quicker... seems sensible to
    me....
    I wish more engineers thought as you do.
    If you do not believe in MAGIC, Consider how currency has value simply by printing it, and is then traded for real assets.

    Gold is the money of kings, silver is the money of gentlemen, barter is the money of peasants - but debt is the money of slaves

    I'm almost out of gas so I'll drive to the nearest gas station even faster so I can run out of gas quicker so I can start walking even sooner!
