I2CWRITE problem

[Art]

Dave,
I can't really use page write because I only want to write 6 bytes at a time.
The code in the first post only writes zeros, but it isn't really what I want in my application... it's just a simplified code that exhibits the problem.

I'm duplicating the hardware today, so this will be interesting.

Art, Are you accumulating the data or just re-writing the values at the same locations? If you are accumulating the values (data logger style (appending)) then just wait till you have 64,128 or so on (eeprom page dependent) , readings stored in the shadow ram then dump them to the eeprom.

That's a lot of bytes of RAM for the 16F877.
I think you get 368 bytes RAM, and PBP consumes some of that.

Art, Like I said, you can use a smaller eeprom like the 24LC256 or 24LC128 which has a 64 byte page write size or as small as a 24LC01B which has an 8 byte page write.

Ah, I get you, sorry. A 24LC256 would be ok.
I will give it a shot when I'm finished my current hardware stuff and get back, it would be a nice improvement for my program.
