Hi

Is there any way to write to internal EEPROM from the C code?

Hi,

Sure there is, look in the manual for the function Write_EEProm().

Of course.

write_eeprom(address, 8bit_value);

also look at the FAQ to write >8-bit values:

or did you mean to ask:

How do I pre-populate the eeprom with certain values while programming the PIC. That's possible too, but i'd have to do a search in the forum for that. I know the topic's been answered a few times before.

Hi

Thank you. Yes you are right about pre- populating the EEPROM.

From a previous thread I understand that have to use: #ROM command.

A few examples:
Code:
// Example to set words:
#ROM 0xF00000 = {1, 2, 3, 4, 5}

// Example to set bytes:
#ROM int8 0xF00000 = {1, 2, 3, 4, 5}

// Example to set a string of bytes:
#ROM 0xF00010 = {"12345"}
