If you are writing raw assembly or C, a poorly timed interrupt during an EEPROM write can cause a system crash or data corruption. Flowcode’s "Exclusive" macros handle this critical sectioning for you. It creates a .
Here is a useful story demonstrating its exclusive role in a real-world project, like a Persistent Industrial Counter The Scenario: The "Never-Forget" Factory Counter
An integer consists of a High Byte (MSB) and a Low Byte (LSB). Use these precise macro steps to save an integer to EEPROM: flowcode eeprom exclusive
Write each array element to its own EEPROM location by referencing specific addresses. This works well for small arrays and gives you precise control over memory mapping.
// Write exclusively as 8‑bit values EEPROM1::WriteByte(address, lowByte) // low byte first EEPROM1::WriteByte(address + 1, highByte) // high byte next If you are writing raw assembly or C,
To appreciate Flowcode’s exclusivity, one must first understand the conventional difficulty of EEPROM programming. In standard C for a PIC or AVR microcontroller, writing a single byte to EEPROM involves:
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. Here is a useful story demonstrating its exclusive
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
