PIC network over AC 220V

[phoenix_1]

Yes, your idea with TDA kicked me to the right direction ))))
I am thinking now about the security of this solution, some kind of encryption or authentication, but anyway your idea was the best !!!

If you need more ideas write me here or on my Email.
I have one question!
Do you have some time problem like address 001F error write on 16F84A!
Today I read this first time in my life (37 year old) and I can read PIC
and I can't erase or write them !!!
PIC is not code protest !!!
I don't know hove to fix this problem - need some idea !!!
Best regards

I would bet of a poor JDM type programmer and IC-Prog? Case not, just tell us which one you're using

How do you program it? in the socket or ICSP?

I programming with ALL programmer ( not JDM ) and I was probe with ICSP to
but last night I was erase all in 16F84A @ 4 MHz , and after reading I was see
that at location 029F still have writen some code !!!
I was replaced that pic with next and board work correct but I want to find
what was hapend with this firs.
Its programmed only 3 times (program memory).Data memory is clear - not usage data location - eeprom inside.

Sorry for may bad english !!!
