To save an integer, you must split it into a and a Low Byte across two consecutive addresses: High Byte Address ( ): (MyInteger >> 8) & 0x00FF Low Byte Address ( ): MyInteger & 0x00FF Reading an Integer (16-bit) from EEPROM: To rebuild the integer upon boot: MyInteger = (ReadAddress(A) << 8) | ReadAddress(A+1) Exclusive Optimization Techniques
Define the total byte capacity based on your target microcontroller's datasheet (e.g., 256, 512, or 1024 bytes).

Mastering Flowcode EEPROM: Exclusive Techniques for Advanced Embedded Developers
Most internal microcontroller EEPROMs are rated for roughly 100,000 to 1,000,000 write cycles per erase sector.
When working with external EEPROM that has more than 256 bytes of storage, address management becomes critical. Some external EEPROM chips require addresses above 255 (0xFF). For I2C communication, note that older microcontroller devices may lock up if there isn’t a between an I2C stop event and the next I2C start event. Most modern microcontrollers don’t have this issue, but it’s worth checking your device datasheet.
This technique is widely used in real‑world Flowcode projects. As one forum user noted about storing counter values up to 9,999: “You can store numbers from 0 to 32767 by using two EEPROM locations, which will be high bytes (0 to 255) and low bytes (0 to 255)”.
