I am using 24LC units, I have two chips wired for addressing as follows: It seems neither writing or reading work.

24C32 – 24C32 4k x 8 Serial CMOS EEPROM

The data sheet for the datasheeet states that it uses a “byte” size variable. My whining goes here. If you can’t get it working, check the MCP sheet for the pic, and look for the register settings for the IC This allowed correct excecution but I don’t know if it was the real cause.

It took me 2. I2c Melanie, Thanks very much for taking the time to reply in full. I don’t know if this is rigth or not, but it seems to be working.


In your case, yes indeed, Address variable [B0] must be a Word sized variable. Problem with I2C 24c32 eeprom.

Like Mulder always said in the X-Files “the answer is out there Surley the address size byte or word depends on the chip not the variable? A small town called Denmark.

Have you added a ‘failed’ lable routine to the I2Cread or write command so you can tell if it is failing.? Steve It’s not a bug, it’s a random feature.

Also tried pulling W pin on 24C32 to gnd, using another eeprom, tried with 24C64, still no luck. I have a similar issue, but have an idea that might help a little. Members who have read this thread: Hi Tom, Yup, I learned about those address bits recently.

I have the same problem you are having – no I2C data!! If I still have some of the above wrong – please reply. There’s no problem, only learning opportunities.

The MELAb code defines the variable properly. Join Date Jul Posts 2, Different than thebut perhaps some of what I just figured out will help you Maybe this update will help out going forward. Results 1 to 13 of It would only take a line to explain that the Control byte always starts datashete What should I try next? The time now is There are some smart folks here tho, and they should be able to help you out. Join Date Sep Posts 2.

Join Date Sep Location montreal, canada Posts 6, 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 I got data back on I2C from the 18F! My program just keeps saying it is failing.
