eeprom editor

[roby]

I have a .hex file. I need to program a 18f4580 with this .hex and edit (and then write to pic) the internal eeprom.
I have a Melabs programmer
Which program may I use?

[PCM programmer]

You could use MPLAB as a Hex file editor.

1. Start MPLAB. Close the workspace, if one exists.

2. Go to the Configure menu and select your PIC.

3. Use the File/Import menu to import the Hex File.

4. Go to the View menu and select EEPROM.

5. Edit the EEPROM data in the window.

6. Use the File/Export menu to save the Hex file. When you export,
a little dialog box will popup. Make sure the tickbox for EEPROM
memory is selected (and also Configuration bits).

For more information, look in the MPLAB Help file. Look in the index
for Import and Export.
