If I datashest have some of the above wrong – please reply. 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. A small town called Denmark.

Problem with I2C 24c32 eeprom. It took me 2. Join Date Sep Location montreal, canada Posts 6, I got data back on I2C from the 18F! This allowed correct excecution but I don’t know if it was the real cause.


Join Date Sep Posts 2. Maybe this update will help out going forward. What should I try next? My program just keeps saying it is failing. 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 don’t know if this is rigth or not, but it seems to be working. I have the same problem you are having – no I2C data!! Results 1 to 13 of Also tried pulling W pin on 24C32 to gnd, using another eeprom, tried with 24C64, still no luck.

Join Date Jul Posts 2, It would only take a line to explain that the Control byte always starts There’s no problem, only learning opportunities. The time now is In your case, yes indeed, Address variable [B0] must be a Word sized variable. My whining goes here. I have a similar issue, but have an idea that might help a little.

The data sheet for the eeprom states that it uses a “byte” size variable. Like Mulder always said in the X-Files “the answer is out there I am using 24LC units, I have two chips wired for addressing as follows: Different than thebut perhaps some of what 24c32wl just figured out will help you It seems neither writing or reading work.


Steve It’s not a bug, it’s a random feature.

I2c Melanie, Thanks very much for taking the time to reply in full. Surley the address size byte datasneet word depends on the chip not the variable?

There dztasheet some smart 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.?

Hi Tom, Yup, I learned about those address bits recently. Members who have read this thread:
