18F4620 and EEPROM
PostPosted: Thu Jun 09, 2005 3:35 pm     Reply with quote
Code:
#ROM int 0xF00000 = {
20,//vol
1,//curfil
0,//seqstart
0,//psound
}


The code above works to put values into eeprom of a 18F452. Now I want to use 18F4620. The code above gives me verify errors so obviously the eeprom data needs to go elsewhere. Where do you guys look to find the eeprom location for a specific chip? I have looked at the data book and I don't see where they print this information.

Thanks.

Go to the programming specifications page on the Microchip website.
http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1407
Download the spec for your PIC:
Programming for PIC18FXX20 Flash MCUs

Look near the end of the document, for this section:
5.6 Embedding Data EEPROM
Information In the HEX File

That's where Microchip gives the address.
It's listed as F00000h.

Make sure that your programming software has the data eeprom
enabled for programming.
