"i basically want to be able to store a program in the serial eeprom and then ru n it through the pic. wich means the pic must extract the code and then execte it. any ideas ??" ok im new to the PIC world and EEPROM world. If i want to write like a list of opcodes to an eeprom i can set it up in assembly and then turn the file into a H EX file with mpasm and all that i can handle...however, when i download the hex file into the serial eeprom, when i read it bak through the software in my PIC i m goin to get like i assume hex number bak, exactly whats written in the PIC. H ow will i convert this bak into the original opcodes. Send someone a cool Dynamitemail flashcard greeting!! And get rewarded. GO AHEAD! http://cards.dynamitemail.com/index.php3?rid=fc-41
