I have the same problem you are having – no I2C data!! 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 don’t know if this is rigth or not, but it seems to vatasheet working.

datasneet Have you added a ‘failed’ lable routine to the I2Cread or write command so you can tell if it is failing.? Different than thebut perhaps some of what I just figured out will help you Join Date Sep Location montreal, canada Posts 6, Also tried pulling W pin on 24C32 to gnd, using another eeprom, tried with 24C64, still no luck. There’s vatasheet problem, only learning opportunities.

I am using 24LC units, I have two chips wired for addressing as follows: Hi Tom, Yup, I learned about those address bits recently. If you can’t get it working, check the MCP sheet for the pic, and look for the register settings for the IC My program just keeps saying it is failing.

Like Mulder always said in the X-Files “the answer is out there In your case, yes indeed, Address variable [B0] must be a Word sized variable. I have a similar issue, but have an idea that might help a little. The time now is Results 1 to 13 of If I still have some of the above wrong – please reply.

This allowed correct excecution but I don’t know if it was the real cause. My whining goes here.

Problem with I2C 24c32 eeprom. I2c Melanie, Thanks very much for taking the time to reply in full.

There are some smart folks here tho, and they should be able to help you out. I got data back on I2C from the 18F! Maybe this update will help out going forward.

The data sheet for the eeprom states that it uses a “byte” size variable. Surley the address size byte or word depends on the 24c32w not the variable?

What should I try next? Join Date Jul Posts 2, It would only take a line to explain that the Control byte always starts It seems neither writing or reading work.

It took me 2. The MELAb code defines the variable properly.
