I don’t know if this is rigth or not, but it seems to be working. Have you added a ‘failed’ lable routine to the I2Cread or write command so you can tell if it is failing.?
Join Date Sep Location montreal, canada Posts 6, There’s no problem, only learning opportunities. It seems neither writing or reading work. If you can’t get it working, check the MCP sheet for the pic, and look for the register settings for the IC 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.

If I still have some of the above wrong – please reply. What should I try next? A small town called Denmark.
There are some smart folks here tho, and they should be able to help you out. Maybe this update will help out going forward. Datasheeg with I2C 24c32 eeprom. Different than thebut perhaps some of what I just figured out will help you It took me 2.

datadheet Also tried pulling W pin on 24C32 to gnd, using another eeprom, tried with 24C64, still no luck. I am using 24LC units, I have two chips wired for addressing as follows: I got data back on I2C from the 18F! Surley the address size byte or word depends on the chip not the variable? My whining goes here.
The time now is Join Date Sep Posts 2. I2c Melanie, Thanks very much for taking the time to reply in full. Hi Tom, Yup, I learned about those address bits recently. Steve It’s not a bug, it’s a random feature.

The MELAb code defines the variable properly. This allowed correct excecution but I don’t know if it was the real cause. I have a similar issue, but have an idea that might help a little. Members who have read this thread: Datasheet program just keeps saying it is failing. In your case, yes indeed, Address variable [B0] must be a Word sized variable. Like Mulder always said in the X-Files “the answer is out there 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 Results 1 to 13 of Join Date Jul Posts 2, I have the same problem you are having – no I2C data!!
