I tried disabling the BBSIZ2K and it did not work.
I verified that only RC1 from portC is the problem.
Ttelmah, in the datasheet it says, by default, the CCP2MX configuration bit equals one, so ... |

I figured out the problem, my Vdd was only getting to around 4.7V. That is why the vref voltage was never where it was suppose to be. I used a similar program to the one you posted and I fixed the V ... |

You were correct, when I slowed the baud rate to 9600 it worked perfect.
In my application I need a baud rate of 57600 so I may have to switch to an 18F which has two hardware UARTS.
Thanks for ... |

Can you explain how I don't have the CPU cycle available?
Correct me if I'm wrong... my clock is running at 7.3728MHz, so one instruction will occur every 1/7.3728MHz = 0.1356uS

I placed some other device on the bus and was able to talk to them so I know my I2C bus is working. So, I then sent only i2c_start(), i2c_write(address) and i2c_stop() and monitored the lines on the ... |

I think something is wrong with my I2C bus. Whether, I have the compass plugged in or not, the bus acts the exact same. I always get a NACK on the 9th clock pulse. I double checked, I have the pin ... |
