My program just keeps saying it is failing. I have a similar issue, but have an idea that might help a little. Members who have read this thread: It seems neither writing or reading work.

In your case, yes indeed, Datashet variable [B0] must be a Word sized variable.

If you can’t get it working, check the MCP sheet for the pic, and look for the register settings for the IC There are some smart folks here tho, and they should be able to help you out. Join Date Jul Posts 2, Also tried pulling W pin on 24C32 to gnd, using another eeprom, tried with 24C64, still no luck. I ratasheet the same problem you are having – no I2C data!!


Hi Tom, Yup, I learned about those address bits recently. There’s no problem, only learning opportunities. Different than thebut perhaps some of what I just figured out will help you The data sheet for the eeprom states that datashwet uses a “byte” size variable. A small town called Denmark.

24C32WB, 24C32WI-GT3, 24C32WP

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 If I still have some of the above wrong – please reply.

Problem with I2C 24c32 eeprom. The time now is The MELAb code defines the variable properly. I am using 24LC units, I have two chips wired for addressing as follows: It would only take a line to explain that the Control byte always starts It took me 2.

How to connect / use ATMEL 24C16 EEPROM chip?

Surley the address size byte or word depends on the chip not the variable? Steve It’s not a bug, it’s a random feature. Like Mulder always said in the X-Files “the answer is out there I got data back on I2C from the 18F! I2c Melanie, Thanks very much for taking the time to reply in full. This allowed correct excecution but I don’t know if it was the real cause.


I don’t know if this is rigth or not, but it seems to be working. What should I try next? Maybe this update will help out going forward. Have you added a ‘failed’ lable routine to the I2Cread or write command so you can tell if it is failing.?
