Hi
I am using the following code having attached a 32.768khz crystal to pins 28,29 of atmega16, the code runs fine in Proteus but not working in real hardware as for incrementing of second minute and hour variable, this is a simple code where i want the time in minutes and not a real clock rather i want to get seconds and minutes to be displayed in 40X4 lcd..





'Procesor Identification ==============================
$regfile = "m16adef.dat"
$crystal = 8000000
$baud = 19200
$hwstack = 128
$swstack = 128
$framesize = 128

'Hardware Configuration ===============================
Config Aci = Off
Config Adc = Single , Prescaler = Auto , Reference = Avcc
Start Adc

Disable Jtag
'Disable 12c
Disable Twi

'Config Clock = Soft

Enable Interrupts
'RTC_Init
Config Timer2 = Timer , Prescale = 128
On Ovf2 Tim2_isr
Enable Ovf2
Assr.as2 = 1 'Timer2 in asynchronous mode





$lib "Lcd4e2.lib"
Config Lcd = 40 * 4

Mcusr = &H80

Ddrd = &B10110010
Ddrb = &B11111111
Ddrc = &B00111111
Ddra = &B00000000



Dim ___lcde As Byte


Dim Second As Byte
Dim Minut As Byte
Dim Hour As Byte
Dim Sec_flag As Byte
Dim Min_flag As Byte


Do

___lcde = 0

'Cls
Cursor Off
___lcde = 1
'Cls
Cursor Off
___lcde = 0
Locate 1 , 1
Lcd " CLOCK SYSTEM "

Locate 2 , 1
Lcd "HOUR " ; Hour


___lcde = 1
Locate 1 , 1
Lcd "MINUTS " ; Minut

Locate 2 , 1
Lcd "SECOND " ; Second




Loop

End



Tim2_isr:
Incr Second

If Second > 59 Then
Second = 0
Incr Minut
End If

If Minut > 59 Then
Minut = 0
Incr Hour
End If

If Hour > 23 Then
Hour = 0
End If
Sec_flag = 1
Return

MOD BY ADMIN


Would you mind to leave your religious stuff out of the forum? I'm a infidel and I feel insulted.


#ADMIN : This forum is not for sharing and discussing religion, politics and the weather. It also means that references to gods, prophets and other religious matters may not be posted. There are zillions forum where you can do that, but not here. Of course the exception is when you make something electronic with BASCOM like an electronic vote system or compass that shows you the east.

Try this.
If it's not working then most likely you have a problem with the hardware.
Are you using something like a breadboard? won't work on that (low freq crystal).

Code:

$regfile = "m16adef.dat"

$crystal = 8000000
$baud = 19200
$hwstack = 40
$swstack = 40
$framesize = 40


Enable Interrupts

'[now init the clock]
Config Date = Mdy , Separator = /                          ' ANSI-Format

Config Clock = Soft                                         'this is how simple it is
'The above statement will bind in an ISR so you can not use the TIMER anymore!

'assign the date to the reserved date$
'The format is MM/DD/YY
Date$ = "11/11/05"

'assign the time, format in hh:mm:ss military format(24 hours)
'You may not use 1:2:3 !! adding support for this would mean overhead
'But of course you can alter the library routines used

Time$ = "23:59:50"
Do
    Waitms 500
    Print Date$ ; Spc(3) ; Time$
Loop
end
