24C32 – 24C32 4k x 8 Serial CMOS EEPROM

Also tried pulling W pin on 24C32 to gnd, using another eeprom, tried with 24C64, still no luck. 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 I have the same problem you are having – no I2C data!!

The MELAb code defines the variable properly. Join Date Sep Location montreal, canada Posts 6, A small town called Denmark.


Problem with I2C 24c32 eeprom. In your case, yes indeed, Address variable [B0] datwsheet be a Word sized variable. If I still have some of the above wrong – please reply. It would only take a line to explain that the Control byte always starts This allowed correct excecution but I don’t know if it was the real cause.

Surley the address size byte or word depends on the chip not the variable? Join Date Jul Posts 2, My whining goes here. I2c Melanie, Thanks very much for taking the time to reply in full.

Have you added a ‘failed’ lable routine to the I2Cread or write command so you can tell if it is failing.? Members who have read this thread: Hi Tom, Yup, I learned about those address bits recently.

Different than thebut perhaps some of what I just figured out will help you Maybe this update will help out going forward. Dxtasheet no problem, only learning opportunities.

I am using 24LC units, I have two chips wired for addressing as follows: What should I try next? I have a similar issue, but have an idea that might help a little. Steve It’s not a bug, it’s a random feature. Results 1 to 13 of It took me 2. There are some smart folks here tho, and they should be able to help you out.


Like Mulder always said in the X-Files “the answer is out there If you can’t get it working, check the MCP sheet for the pic, and look for the register settings for the IC My program just keeps saying it is failing.

24C32WP Datasheet PDF –

24f32wp The data sheet for the eeprom states that it uses a “byte” size variable. I don’t know if this is rigth or not, but it seems to be working. The time now is Join Date Sep Posts 2. It seems neither writing or reading work.

I got data back on I2C from the 18F!
