Микроконтроллеры

ИМХО, стоит попробовать пользоваться своими функциями. Например: <c> unsigned char eeprom_getc(unsigned char __eeprom *addr) { /* Wait for completion of previous write */ while(EECR & (1 << EEWE)) ; __disable_interrupt(); /* Set up address register */ EEAR = (unsigned int) addr; /* Start eeprom read by writing EERE */ EECR |= (1 << EERE); /* Return data from Data Register */ EEAR = 0; __enable_interrupt(); return EEDR; } void eeprom_putc(unsigned char c, unsigned char __eeprom *addr) { /* Wait for completion of previous write */ while(EECR & (1 << EEWE)) ; __disable_interrupt(); /* Set up address and Data Registers */ EEAR = (unsigned int) addr; EEDR = c; /* Write logwical one to EEMWE */ EECR |= (1 << EEMWE); /* Start eeprom write by setting EEWE */ EECR |= (1 << EEWE); EEAR = 0; __enable_interrupt(); } </c> А дальше смотреть. Может проблемы с питанием.
