There’s no problem, datahseet learning opportunities. Steve It’s not a bug, it’s a random feature. The data sheet for the eeprom states that it uses a “byte” size variable.

It would only take a line to explain that the Control byte always starts 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.? Maybe this update will help out going forward.

This allowed correct excecution but I don’t know if it was the real cause. Join Date Jul Posts 2, My whining goes here.


Members who have read this thread: 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 datqsheet I2C bus In your case, yes indeed, Address variable [B0] must be a Word sized variable. The MELAb code defines the variable properly.

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. Different than thebut perhaps some of what I just figured out will help you I got data back on I2C from the 18F!

If you can’t get it working, check the MCP sheet for the pic, and look for the register settings for the IC A small town called Denmark. It took me 2.

Surley the address size byte or word depends on the chip not the variable? I2c Melanie, Thanks very much for taking the time to reply in full. My program just keeps saying it is failing. It seems neither writing or reading work. I have a similar issue, but have an idea that might help a little. Results 1 to 13 of The time now is Join Date Sep Location montreal, canada Posts 6, I don’t know if this is rigth or not, but it seems to be working. I am using 24LC units, I have two chips wired for addressing as follows: Problem with I2C 24c32 daasheet.

Hi Tom, Yup, I learned about those address dwtasheet recently. Join Date Sep Posts 2. Like Mulder always said in the X-Files “the answer is out there What should I try next?

There are some smart folks here tho, and they should be able to help you out.
