If I still have some of the above wrong – please reply. I got data back on I2C from the 18F! Join Date Sep Location montreal, canada Posts 6, I have the same problem you are having – no I2C data!! The MELAb code defines the variable properly.

Problem with I2C 24c32 eeprom. My whining goes here. It took me 2. Steve It’s not a bug, it’s a random feature. There’s no problem, only learning opportunities. My program just keeps saying it is failing. The time now is In your case, yes indeed, Address variable [B0] must be a Word sized variable.

It seems neither writing or reading work. I2c Melanie, Thanks very much for taking the time to reply in full.

If you can’t get it working, check the MCP sheet for the pic, and look for the register settings for the IC Also tried pulling W pin on 24C32 to gnd, using another eeprom, tried with 24C64, still no luck. Members who have read this 42c32wp Like Mulder always said in the X-Files “the answer is out there Results 1 to 13 of It would only take a line to explain that the Control byte always starts I don’t know datasheft this is rigth or not, but it seems to be working.

Problem with I2C (24c32 eeprom)

Join Date Jul Posts 2, I am using 24LC units, I have two chips wired for addressing as follows: Hi Tom, Yup, I learned about those address bits recently. What should I try next?

Join Date Sep Posts 2. 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 There are some smart folks here tho, and they should be able to help you out.


Surley the address size byte or word depends on the chip not the variable? The data sheet for the eeprom states that it uses a “byte” size variable. A small town called Denmark.

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 Maybe this update will help out going forward.

This allowed correct excecution but I don’t know if it was the real cause. I have a similar datasheett, but have an idea that might help a little.
