7-segment display with P16F84

[hoops2006]

Many thanks for your reply spitefire just what i needed. I made a boxing round timer a while back, now im trying to improve it by displaying the time on a 7 seg display. its proving to be tricker than i thought. As im still struggling to get my head round this one as im a newbie to pics your extra info helped alot.

No worries hoops, nice project there. Have you got the hardware side finished yet?

I'm also somewhat of a newbie to PICs but after studying discrete logic and designing a 24 hour clock with cmos 4000 series IC's (made my own 4 digit 7-segment display on veroboard using 58 blue LEDs) I now unterstand abit better.

I'm interested to see how it turns out.

Yes i think i have a fair idea of the hard ware. Pretty much the same set up as the link you gave on the first post. Two microswitches for round selection .With a relay chunked in for the buzzer. But my objective for now is to get minutes and seconds counting down on the display. Once i have that ill start worrying about how to select the times i want ect,

So i have plenty to keep me going. ill keep you posted.

Would a count down timer be as simple as:

for sec=59 to 0
pause 1000
if sec=0
then minutes=minutes-1
gosub display.

the value for display would be (minutes*100)+sec eg if 3mins 59 sec value 359
then just display the value as per the code on the link.
