Most Arduino boards have real EEPROM: memory whose values are kept when the board is turned off (like a tiny hard drive), but the 86Duino does not. Instead, we implement virtual EEPROM on 86Duino using two approaches: one realizing a 16 KB virtual EEPROM in the onboard SPI flash with an advanced virtual EEPROM algorithm, and the other realizing a 200-byte virtual EEPROM using the onboard CMOS memory.
This library enables you to read and write bytes in these virtual EEPROM.
When you use the 86Duino SysImage tool to update the 86Duino’s Firmware system in the onboard flash, the content of the two virtual EEPROM will simultaneously be erased.
