| Hi there!
I hadn't tried your code, but i found the problem. It looks like the I2C Port of my �C is broken down. I am not sure why, but if i take another controller of the same type, with the sa ... |

| Hi!
My hardware is OK. I have installed pull up resistors and i have 5 Volts on SDA and SCL when the bus is idle. The values of the resistors are 4k7 The code from my testing program: #inclu ... |

| Hi!
Since a few days, i have a big problem. When i process an i2c_write() command on my PIC 16F747 via the hardware I2C - Interface, the �C hangs! I have no ideas, whats wrong with my controlle ... |

Oh god! 
I think, i haven't read this. I always thought, that there could be mor than one EEPROMs of this type on the bus. I thank you really very much and this is the explanation why i ... |

| Thanks for your respond!
But i change the Hardware address (the pins A0-A2 at the EEPROM) and i always get data even if the hardware address and the address specified in my program don't match. An ... |

| Hi!
I've a very curious problem: I try to communicate with a I�C EEprom (Microchip 24AA02). I think (but i'm not sure) that i am able to write data into the EEPROM but when i read the data, i get ... |

| Like MikeValencia said, i'd say, that i would be the best to implement some messages into your program to see, in which state the �C is (and the easiest way is to do this via the RS232 interface).

| Hi boys!
I've a short question: What is the internal frequency of the PIC, when i use the internal RC oscillator?? Are this the 31.25 kHz mentioned in the datasheet?? Markus |

I've found the problem! In the device editor, both has to be enabled (i2c master AND slave). In my case, only Master was enabled and therfore, the compiler wasn't able to produce code for HW ... |
