The time now is I2c Melanie, Thanks very much for taking the time to reply in full.

If I still have some of the above wrong – please reply. I am using 24LC units, I datasheeet two chips wired for addressing as follows: Members who have read this thread: Maybe this update will help out going forward. Also tried pulling W pin on 24C32 to gnd, using another eeprom, tried with 24C64, still no luck.

This allowed correct excecution but I don’t know if it was the real cause. There are some smart folks here tho, and they should be able to help you out.

Join Date Sep Location montreal, canada Posts 6, Problem with I2C 24c32 eeprom. If you can’t get it working, check the MCP sheet for the pic, and look for the register settings for the IC In your case, yes indeed, Address variable [B0] must be a Word sized variable. I datashet the same problem you are having – no I2C data!!

Hi Tom, Yup, I learned about those address bits recently. 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?

Join Date Sep Posts 2. I have a similar issue, but have an idea that might help a little.

It seems neither writing or reading work. 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 What should I try dayasheet

The MELAb code defines the variable properly. Steve It’s not a bug, it’s a random feature. My program just keeps saying it is failing.

The data sheet for the eeprom states that it uses a “byte” size variable. A small town called Denmark. My whining goes here. Have you added a ‘failed’ lable routine to the I2Cread or write command so you can tell if it is failing.?

I got data datassheet on I2C from the 18F! Different than thebut perhaps some of what I just figured out will help you I don’t know if this is rigth or not, but it seems to be working.
