Do you have a method to program a 24xxx chip right now?
Yes.
Now I program the 24 using Olimex JDM programmer:

Using the ICSP header I connect them as:

3-Gnd-->gnd of 24CX
4-PGD-->Data of 24CX
5-PGC-->Clk of 24CX

Using windows Pic progarmming software, I can program the 24X

But not by 16f84a.
Could this be a voltage issue ? or Should I try something else than i2cwrite ?

Thanks
