Viete mi niekto prosím povedať kde robím chybu?
Dokážem zapísať v PIC údaje do EEPROM, ale keď chcem spraviť viac zápisov, tak zapíše sa len ten čo je v kóde prvý.
Opakujem tam túto časť kódu akurát zakaždým s inou adresou.
WREN = 1; // povolenie EEPROM
EEADR = 0x00;
EEDATA = 0x11;
EECON2 = 0x55;
EECON2 = 0xAA;
WR = 1; // spustenie zapisu
WREN = 0; //zakaz EEPROM
EEIF = 0;
