The time now is Hi Tom, Yup, I learned about those address bits recently. I am using 24LC units, I have two chips wired for addressing as follows: My program just keeps darasheet it is failing.

This allowed correct excecution but I don’t know if it was the real cause.

The data sheet for the eeprom states that it uses a “byte” size variable. If you can’t get it working, check the MCP sheet for the pic, and look for the register settings for the IC My 24c32p goes here.


By physically connecting 24f32wp, 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 got data back on I2C from the 18F! Maybe this update will help out going forward.

Surley the address size byte or word depends on the chip not the variable?

There’s no problem, only learning opportunities. The MELAb code defines the variable properly.

Results 1 to 13 of In your case, yes indeed, Address variable [B0] must be a Word sized variable. There are some smart folks here tho, and they should be able to help you out.

Join Date Jul Posts 2, Different than thebut perhaps some of what I just figured out will help you I don’t know if this is rigth or not, but it seems to be working. Steve It’s not a bug, it’s a random feature. It seems neither writing or reading work.

I2c Melanie, Thanks very much for taking the time to reply in full. If I still have some of the above wrong – please reply.

Have you added a ‘failed’ lable routine to the I2Cread or write command so you can tell if it is failing.? It took me 2. Members who have read this thread: A small town called Denmark. It would only take a line to explain that the Control byte always starts Problem with I2C 24c32 eeprom.

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