Pic887, New to programming, Clock.

Using PicBasic Pro (new to it this year) and I'm trying to make a relatively simple clock. I'm sure this code isn't that great and there are improvements I can make to it to make it shorter and more simple, but as of now it works ok.
I'm using 3 2-7-Segment displays that are multiplexed.
Anyways, here's the code I'm working off of (remember I just started, also this code still needs to add the 3rd set of 7 segments, but I could figure that out with the advancing from the first set!)
Pretty much I need some help getting each set of 7 segments to count on their own, and then advance the count on the next digit, but making that set of 7 segments still count on their own timer. Hopefully that made sense. I'd like it to just be some tips on how to do it, but if you have to just tell me flat out, that works too.
Thanks, if you have any questions I'll try to answer them the best I can, but remember I'm still new to this.
(If this needs to be posted somewhere else, I will move it)

Hi,
There seems to be something wrong with the attachment so I can't look at your code and I'm not exactly shure what you're asking. Do you have a 6 digit display that will display elapsed time in seconds or do you have 3pcs of 2-digit displays that will all display elapsed time in seconds but independently of each other or do you have a 6 digit display that will display elapsed time in hours:minutes:seconds format?

But basically, each time you increment a digit you check if it rolled over, if it did you increment the "next" digit, check if IT rolled over and so on. If you have three digits showing elapsed time in seconds then something like this:

Code:

---

Ones = Ones + 1
  If Ones = 10 THEN  ' A single digit can only display 0-9
    Ones = 0
    Tens = Tens + 1
    If Tens = 10 THEN
      Tens = 0
      Hundreds = Hundreds + 1
    ENDIF
  ENDIF

---

The same tecnique can be adopted to any number of digits, to hours:minutes:seconds or a countdown timer etc.

/Henrik.

Yeah sorry about being so unclear. I'm using 3 sets of 2-7 segment displays. I pretty much need the first digit to count and then from there I can just up the count on the others once that digit hits 10.

Here's the code since I cannot get the attachment to ever work.
