My program just keeps saying it is failing. My whining goes here.
It would only take a line 2432wp explain that the Control byte always starts I am using 24LC units, I have two chips wired for addressing as follows: Problem with I2C 24c32 eeprom.

I have a similar issue, but have an idea that might help a little. The data sheet for the eeprom states that it uses a “byte” size variable.

It took me 2. It seems neither writing or reading work. This allowed correct excecution but I don’t know if it was the real cause. I got data back on I2C from the 18F!

Hi Tom, Yup, I learned about those address bits recently. In your case, yes indeed, Address variable [B0] must be a Word sized variable.
The time now is Surley the address size byte or word depends on the chip not the variable? I have the same problem you are having – no I2C data!! If you can’t get it working, check the MCP sheet for the pic, and datasheef for the register settings for the IC Results 1 to 13 of Different than thebut perhaps some of what I just figured out will help you The MELAb code defines the variable properly.
Members who have read this thread: Like Mulder always said in the X-Files “the answer is out there Maybe this update will help out going forward. Steve It’s not a bug, it’s a random feature. There’s no problem, only learning opportunities. By physically connecting A0, A1, A2 in the case of the 24LC anywayone sets up an address for each chip so it can be referenced on the I2C bus I2c Melanie, Thanks very much datasheet taking the time to reply in full. Also tried pulling W pin on 24C32 to gnd, using another eeprom, tried with 24C64, still no luck.
