Hex Editor for EEPROM

[exelanoz]

Curious how you edit an eeprom chip with a PC hex edit program?

Hello Norm,

Thnx for the link. So that I can better explain what I am doing, I've attached 2 screen shots, first is from IC-Prog and then from UPA2.3

I open the hex file, then where the highlighted pink area is, I make additions or amendments and then save and write onto the EEPROM chip.

But using these programs / method it is quite tedious if you want fill up the entire EEPROM - - especially a 24LC256...

There must be an easier way. When I open the same hex file in your suggested program, it doesn't interpret the data correctly and shows 'garbage' that I can't understand...:-)

I might have the wrong view enabled...dunno.

A while ago I had a program that worked in a DOS window, I could very easily move around and change things. I don't remember the name or where I saved it on my HD...

Maybe I am doing it the wrong way?
