[microkam]

,i download the new programe on the 16f877 and all thing is ok

I interchange 18F252, 18F242, 18F2420, 18F2520 and 18F2620 with 16F876's all the time, on the same boards with a DS1307 installed (although I use different pins to you). From memory, other than CONFIG FUSES and the Weak Pull-Up's having a different Register, there's not too many other changes to look out for. Can you try another 18F PIC? what versions of PBP and MPLAB/MPASM are you using?

[microkam]

i used picbasic pro 2.4
microcode studio 2.0.5.2
mpasm v02.80
whats the state of fuses you use
i used HS are this correct

i used picbasic pro 2.4
microcode studio 2.0.5.2
mpasm v02.80
whats the state of fuses you use
i used HS are this correct

There are newer Versions of all the packages available.
(MicroCode Studio and MPASM are available for download)

With regards to the Fuses and Config Bits:
The Loader.HEX usually has all this preset, so you don't have to worry.
(As long as your programmer doesn't alter them)

ok NavMicroSystems , whats the soluation i tested all thing and no result

PBP version 2.42 introduced some timing changes to I2CREAD/I2CWRITE for
the 18F series. That may be why you're having problems if you're using
version 2.40.

I've compiled your code as-is with PBP v2.46. See if this works for you.
