Hex Editor for EEPROM

[exelanoz]

Hello!

I am looking for a recommendation for a Hex Editor that I can use with my 24LC16B eeprom.

I have made a display project, where the PIC16F628 reads some values off sensors, makes the calculations and then reads some display data off the eeprom and then send it to a LCD and 6x Max7219 LED Displays...

To edit the ASCII contents of the EEPROM, I use UPA2.3 Lite version.I have tried others that I have found via google, but not really happy with any of them, some won't even display the ASCII equivalent.

UPA2.3 - It's OK, but not efficient. It can be a little tedious...Can anyone recommend or make any suggestions on how I can edit the ASCII data on the EEPROM efficiently?
I don't mind if it is dos or windows based.

Many thanks

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
