Hi,
I am trying to write and read eeprom 24C16. However it does not work.
Did you ever did it ? I am using 16F84, 4MHz oscillator, SDA to RB7, SCL
to RB6. Using Resistor pull-up to Vcc, 22k in, in SDA and SCL. I think
the circuit is correct. I checked the voltage too.

I followed the instruction in Application Notes AN567 and others,
modified it to run at  16F84. I just write and read 1 byte. However, my
16F84 just read FF.

Do you have any advises about it ? Is the algorithm wrong ? or Should I
buy the new eeprom?

Thanks a lot for your help.

Regards,
Harry
