Hex Editor for EEPROM

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

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?

Looks like you need PSPAD.

Goto http://www.pspad.com It is a programmers text editor with hex editor built in. Highly recommended for daily use. Also has a diff tool built into it.

Hello Darrel & Jerson,

Thx for the links.

Darrel - I've tried the program - yes, you can navigate quite easily, but it still doesn't display the data the way I want it to. I've attached a small screenshot clip to show you what I mean.
Jerson's suggestion looks even fancier, but still doesn't interpret the data.

That is exactly the same file the IC-Prog and UPA2.3 can open with the Characters equivalents showing on the side.

I open the same file in XVi32 and my screenshot shows how it is displayed.

My aim is to fill up the EEPROM on the PC, then put it in circuit and disable the write feature by connecting the WP pin to the Vcc. The pic chip will never need to write to it.

I can use IC-PROG and the other to fill it up, but it doesn't navigate real well.

i must be doing it the wrong way - or i may have the wrong settings within the editor. I've tried all kinds of option in the menus for displaying the data, but I have had no luck in correctly displaying it.

Many thanks

AP

I guess I don't understand.

That's the way I'd expect to see a HEX editor.

How are you expecting it to be displayed?

No...No...it's probably me doing things in a non-conventional way. :-)

I sometimes hold my soldering iron back to front. :-))))

For example: Have a look at my earlier post with screen shot A or B

I highlighted the characters saved on the EEPROM in the Pink section.
See how they are 'human' readable.
Yet, that same file in XVi32 displays like my screen shot C. And the right column has a bunch of numbers that is not 'human' readable.

Sorry it might be my bad explanation, or I am doing it the wrong way.

Thnx
