PIC EEPROM Data to PC

Started by Paul March 15, 2006
Hi. How would i go about transfering my EEPROM Data from the PIC to 
either a PC or Floppy/Memory Card? I am currently looking on the Net 
for info, but just wondering if anyone has done this or have any 
information to help me?

Cheers

Simplest is serial link. Bit bang it if you have to.
Capture with Hyperterm. Use commas to separate data fields
and you can easily import saved file into a spreadsheet.
Interface is as simple as 74HC14 and some series resistors.

Next easiest is using a memory card in '1bit' mode.
Basically SPI. Lots of web docs out there on how to do that.
Look for 'SD card PIC data logger' for lots of hits.
Digikey has the card connectors. (Hirose)
Big headache is that you have to write the card in FAT16 or
FAT32 format for a PC to understand it without a special driver.

HI Paul,

How much data?

You can probably use MPLAB, "view" the EEPROM, copy/paste it to a text
editor.  I have done that with the program memory view after loading hex
code that I don't have the source code for (a partial disassembly).

In this case you'd just have a HEX code dump; but with a little trimming
with the editor you can then create an array for a source file.  The file
can then be assembled/compiled, and a proper hex file generated.

At one time I had a utility that would generate a proper hex file from a
simple trimmed HEX dump.  Not too hard to write.  Mostly you need to
calculate the checksum and add the Intel (or whatever) format.

From a HEX file you should be able to write it where ever you want.

You can read it directly from some programmers.  IC-Prog will do it.
