Flowcode EEPROM Exclusive: Mastering Non-Volatile Memory in Embedded Systems
The practical utility of Flowcode’s exclusive EEPROM handling can be demonstrated through two typical embedded projects: flowcode eeprom exclusive
: Unlike standard RAM variables, EEPROM retains its value after a reset or power cycle. EEPROM is the preferred storage location for user‑defined
In your flowchart, you will use the following main functions: Saves a value to a specific address. Read(address) : Reads a value back from an address. This is only possible because EEPROM is —it
EEPROM is the preferred storage location for user‑defined passcodes in electronic lock systems. When a user changes the default passcode (e.g., from “1234” to a new 6‑digit code), the new code is stored in EEPROM. If power is lost, the system remembers the new passcode when power is restored. This is only possible because EEPROM is —it retains data during power cycles.
Once all data writes finish successfully, write 0xAA (or any specific validation token) back to Address 0 .
An integer consists of a High Byte (MSB) and a Low Byte (LSB). Use these precise macro steps to save an integer to EEPROM:
