Hi, Piclisters

I am developing a project where I want to communicate a 16F877
with an external computer and to be able to read/write an i2c
serial eeprom (24C64) and all these tasks interrupt driven.

I have ended with a huge assembly program with lots of interrupts
(serial in, serial out, tmr0, i2c ...) where everything works
except the reading from the serial eeprom. I am trying to debug
the program but I only have a dual trace scope and the data that
I get from the serial line to try to ascertain what is going
wrong. It seems that the eeprom writing is OK (?) : the signals
in the clock/data lines seem to look like what they should but
I cannot recover the data I wrote.

Has somebody a piece of code with an interrupt driven piece of
code to read and write serial eeproms ? It would be a big help for
me to try such a program and then to add to it the other features
I have already developed and tested.

Thanks a lot for your help
