UberNewbie can't set his clock...

[Byte_Butcher]

Thank you sinoteq !

I tried the code without the $ in front of the variables, and using DEC2 instead of HEX2 in the LCDOUT command as you suggested, and now the button to set the time works fine. BUT, the time no longer displays correctly.

Now it skips certain numbers (groups of 6 it seems) as it goes from 0 to 60, and it counts to 90 instead of 60 before it increments the minute and resets seconds to 0...

So now the time "increment minutes" button goes from 0 to 60 then resets as is desired, but the time displayed from the RTC goes to 90 seconds and skips numbers.

I'm open for more suggestions!

Thanks,
Steve

If you look at the datasheet for the DS you will se that you have to do some formating of the DS result before you can display it. The DS does not store each SEC MIN HOUR and so on as a byte, it is stored in a mixed byte (I bet Melanie knows the correct word for it)

Example:
The register for seconds is 8 bits wide but is split into a 10 SEC part and a SEC part. So you have to look at the DS data as (n*10SEC)+SEC.
You have to move this into a byte before you can display it. I have never used DS1302 but I have used the DS1307 and the idea is similar.

Please look at http://pdfserv.maxim-ic.com/en/ds/DS1302.pdf Table 3 page 9

Melanie has all kinds of words for all kinds of situations... but in this instance I'll chose to use BCD (Binary Coded Decimal)...
