Solved ✔ EEPROM reading
Hi,

I'm trying to figure out how to R/W an EEPROM from a IC.
It is mandatory to desolder the EEPROM for reading, or it can be read directly from PCB with the clip adapter?

Thanks.

RE: EEPROM reading
In general its considered best to always remove eeprom from the circuit to minimise the possibility of corrupt data.

RE: EEPROM reading
If the EEPROM is read from PCB, is there a way to verify that the file is corrupted?

Not until it is too late. rolling

Some can be corrupted merely by trying to read them, specially with cheap programmers and inexperienced users.

If someone took the time to help you, the least you can do is take a few seconds and press two buttons!

RE: EEPROM reading
So in other words, with a clone Digiprog 3 is better to desolder before doing anything.

RE: EEPROM reading
And save a backup of the original using the eeprom menu before trying to change anything.

RE: EEPROM reading
Haha!
Don't worry, I understand what you mean!

Last question, does it's better to solder a new EEPROM or keeping the old one?

RE: EEPROM reading
The old one is fine, I have never changed an eeprom.

Unless you are working with some 35080.

And I see you are fairly new here....
