Hi All i have just got an AXE033 and hooked to an 28X chip and am wanting to display the time via i2c on the LCD.

using the following Code I Borrowed From Michael V (Thanks)..

Code:
'clock display in i2c mode
'Write to Serial LCD.


init: 
pause 500
i2cslave $C6, i2cslow,i2cbyte	

main: writei2c 0, (254,128,255)
pause 10
writei2c 0, ("THE Time is", 255)

pause 500


if pin0 = 1 then settime

i2cslave %11010000, i2cslow, i2cbyte	'DS1307 Clock chip

readi2c 0,(b0,b1,b2)
pause 30


clock:i2cslave $C6, i2cslow,i2cbyte 	

writei2c 0, (254,192,255)
pause 30

b4=b0 & %00001111

b3=b0 & %11110000
b3=b0/16

b3=b3+$30	' (or you could do b1=b1 + '0')
b4=b4+$30	'



b6=b1 & %00001111

b5=b1 & %11110000
b5=b1/16

b5=b5+$30	' (or you could do b1=b1 + '0')
b6=b6+$30	'



b8=b2 & %00001111

b7=b2 & %11110000
b7=b2/16

b7=b7+$30' (or you could do b1=b1 + '0')
b8=b8+$30'

writei2c 0, (b7,b8,":",b5,b6,":",b3,b4,255 )


low 0			'flash LED on Pin 0
pause 50
high 0

debug b0


goto init

settime:
high 6
pause 50
i2cslave %11010000, i2cslow, i2cbyte
writei2c 0, ($00, $59, $11, $03, $25, $12, $03, $10)
pause 50
low 6

goto init
The problem I have is that when I Make pin 0 = 1 and the time sets it never starts counting
the display only reads THE time is 11:59:00

I have tried a number of DS1307's with the same result..

Any help would be great..

Cheers

Have a check of the little silver watch crystal to make sure it is soldered correctly.
