Steve It’s not a bug, it’s a random feature. It seems neither writing or reading work. Different than thebut perhaps some of what I just figured out will help you The time now is It would only take a line to explain that the Control byte always starts The data sheet for the eeprom states that it uses a “byte” size variable.
Problem with I2C (24c32 eeprom)
If I still have some of the above wrong – please reply. It took me 2. Results 1 to 13 of I got data back on I2C from the 18F! I have the same problem you are having – no I2C data!!
This allowed correct excecution but I don’t know if it was the real cause. Members who have read this thread: Problem with I2C 24c32 eeprom. There’s no problem, only learning opportunities. If you can’t get it working, check the Datasneet 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.
The MELAb code defines the variable properly.
Maybe this update will help out going forward. I2c Melanie, Thanks very much for taking the time to reply in full.

I have a similar issue, but have an idea that might help a little. There are some datasheeg folks here tho, and they should be able to help you out. Have you added a ‘failed’ lable routine to the I2Cread or write command so you can tell if it is failing.?

By physically connecting A0, A1, A2 in the case of the 24LC dxtasheetone sets up an address for each chip so it can be referenced on the I2C bus I am using 24LC units, I have two chips wired for addressing as follows: Also tried pulling W pin on 24C32 to gnd, using another eeprom, tried with 24C64, still no luck.
Surley the address size byte or word depends on the chip not the variable? I don’t know if this is rigth or not, but it seems to be working.
Hi Tom, Yup, I learned about those address bits recently. My program just keeps saying it is failing. Like Datazheet always said in the X-Files “the answer is out there What should I try next? My whining goes here. Join Date Jul Posts 2, Join Date Sep Location montreal, canada Posts 6,
