24C32WP Datasheet, PDF – Qdatasheet

Maybe this update will help out going forward. Steve It’s not a bug, it’s a random feature. Join Date Sep Location montreal, canada Posts 6, There’s no problem, only learning opportunities.

Hi Tom, Yup, I learned about those address bits recently. Join Date Sep Posts 2.

Also tried pulling W pin on 24C32 to gnd, using another eeprom, tried with 24C64, still no luck. In your case, yes indeed, Address variable [B0] must be a Word sized variable. Problem with I2C 24c32 eeprom.


A small town called Denmark. Members who have read this thread: I2c Melanie, Thanks very much for taking the time to reply in full. It seems neither writing or reading work.

What should I try next? My whining goes here.


I have a similar dattasheet, but have an idea that might help a little. Join Date Jul Posts 2, I have the same problem you are having – no I2C data!! It would only take a line to explain that the Control byte always starts I got data back on I2C from the 18F!

The data sheet for the eeprom states that it uses a “byte” size variable. There are some smart folks here tho, and they should be able to help you out.

Surley the address size byte or word depends on the chip not the variable? My program just keeps saying it is failing. This allowed correct excecution but I don’t know if it was the real cause. 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 Have you added a ‘failed’ lable routine to the I2Cread or write command so you can tell if it is failing.?


Different than thebut perhaps some of what I just figured out will help you The time now is Like Mulder always said in the X-Files “the answer is out there Results 1 to 13 of I am using 24LC units, I have two chips wired for addressing as follows: I don’t know if this is rigth or not, but it seems to be working. If you can’t get it working, check the MCP sheet for the pic, and look for the register settings for the IC The MELAb code defines the variable properly.

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