ds1307 from f877 to f452 not work

[NavMicroSystems]

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.

hi Bruce...
i downloaded your hex file and it's runing ok.
how can i solve this problem on my compiler picbasic pro 2.4 because i dont have a newer version than 2.4..

Version 2.40 is pretty old. If for some reason you can't upgrade to the latest
version, then you might try contacting MeLabs directly to see what changes
they made to the 18F I2C library routines.

Look here http://www.microengineeringlabs.com/...pgrade.htm#pbp

They've had a LOT of updates since v2.40 for the 18F series. Well worth the
few bucks for an upgrade if you're using 18F parts.

microcam,

this is probably not what you wanted to hear,
but best would be to upgrade to PBP 2.46

[microkam]

Contact the distributor you originally purchased PBP from. They should be
able to get you going.
