Convert to decimal

Arch

Using the template from DS1302template.bs2, and then having it the real time clock displayed on my LCD appmod Terminal, however I am missing the digits 8 and 9. Meaning that for the seconds, it goes from 40, 41, 42, 43, 44, 45, 46, 47, 40, 41, 50.
I understand that it has got to do with converting of BCD to decimal value. I've tried a few ways that were mentioned in the previous forum.. none of them really works.. Could anyone advise me on this?

I don't have a copy of DS1302template.bs2, so I can't advise you specifically, but it looks like you're dropping the 8 bit of the least significant digit of the seconds value. Somewhere you have a mask of $7 when you should have a mask of $F. Post your code as an attachment to a reply.

Thanks Mike. I've attached my file. Anyway, This is the portion of the code where LCD_Date is displaced. Many thanks

LCD_Date:
GOSUB ClearScreen

value = (hrs >> 4) * 10 + (hrs & $0F) 'To set the display of hours to LCD appmod, convert to ASCII before writiing.
GOSUB C_ASCII

value = (mins >> 4) * 10 + (mins & $0F)
GOSUB C_ASCII


value = (secs >> 4) * 10 + (secs & $0F)
GOSUB C_ASCII

RETURN

I can't see anything wrong with the code that writes the time values to the LCD. Maybe one of the connections to the LCD is bad. Try writing characters like "@ABCDEFGHIJKLMNO". The "HIJKLMNO" may show up as "@ABCDEFG" if I'm right.

char = "@"
call Write_LCD_Char
char = "A"
call Write_LCD_Char
' ... and so on
