EEPROM DATA RECOVERY METHOD OF EMBEDDED SYSTEM

摘要

A method for employing EEPROM data recovery in an embedded system is provided to store plural sets of data in an EEPROM and, even if there occurs an error at one among the plural sets of data, to maintain smoothly a system by using other sets of data. A method for employing EEPROM data recovery in an embedded system comprises the following several steps. A micro control unit loads the first set of data of the EEPROM(S100). The micro control unit inspects the loaded data via a check code and determines whether the loaded data is legal(S200). If there occurs an error at the data, the micro control unit loads the next set of data from the EEPROM(S300). The micro control unit inspects the loaded next set of data by using the check code(S400). If there occurs no error at the new loaded data, the micro control unit replaces the first set of data with the next set of data(S500).
