I have been using DS1307 Real Time Clocks for some time now without problems. I am attempting to port a program I wrote a while back from a 18f4620 to a 18f46k22 and I can't seem to get the I2C RTC to communicate. The only thing I can see different should be the speed of the micro running at 16MHz instead of 8MHz.
I did try adding "DEFINE I2C_SLOW 1" without any luck. Any suggestions?

Thanks,

Jim Black
