Wacth

[jgu1]

Hi Team!

I am trying to make a simple wacth. I use a Pic18f4525 on EB006 board and 19.0668 Mhz Xtal. But already after few minute I lose second´s. Please would some of your expert be so kind to check the program and se if I made some fault. I suspect the hardware (Xtal).

Hello,

I have made a couple of minor mods to your program and hopefully it should now run correctly for you. I think the problem before was that you were calling the display macro from the interrupt which means you may be in the interrupt routine too long and miss timer counts.

I also moved the reset of the timer count variable as there was a possibility that it would not be reset which again would lead to the timer not counting the time correctly.

Hi Ben

Unfortunately did not help. I must try to change the crystal, it may well be not running as it should. But otherwise, many thanks for your help.

Before you change crystal, try this version.
The problem you had with your Flowchart is you 1st check to see if seconds = 60, then if not the seconds are incremented by 1. So if seconds = 59 then 1 is added to the second.
This means that each minute is incremented every 61 seconds and not every 60 seconds.
So to correct I have changed Sek=60 to Sek=59 and same with mins. Normaly you add 1 to seconds, then check to see if seconds = 60.
I have also completed some other minor alterations.

Hi medelec.

Yes, yes. Now fit the time, 100% Even small mistakes can have large fluctuations.
Now I can get on with the project. I must have created the opportunity to set the time, but it's no problem.
So far many thanks for the quick response and help when I find out how to do, you get many stars.
