Flowcode eliminates these barriers through its exclusive , which is part of its broader “Storage” palette. This component is not a mere code generator; it is an abstraction layer that provides a clean, macro-based interface. The user drags and drops the EEPROM component onto the 2D dashboard or system panel, and immediately gains access to two primary macros: ReadByte and WriteByte . Each macro requires only an address (0 to maximum EEPROM size) and a data byte (for write) or a return variable (for read).
The standard Flowcode EEPROM component works strictly with 8-bit bytes. Real-world applications, however, rely on 16-bit integers, 32-bit longs, and floating-point variables. To save these data types, you must decompose them into individual byte streams. Splitting and Merging Integers (16-bit)

To store a 16-bit variable ( My_Integer ) into EEPROM addresses 0x10 and 0x11 , utilize bitwise operators or mathematical division within a Flowcode Calculation Icon. Low_Byte = My_Integer & 0xFF Extract High Byte: High_Byte = (My_Integer >> 8) & 0xFF
A common task is storing an array of values in EEPROM. For example, if you have an array of 10 sensor readings, you might write: Flowcode eliminates these barriers through its exclusive ,
The finite write cycle endurance of EEPROM is a silent killer of embedded systems. An exclusive technique is to implement a circular buffer or a journaling system within EEPROM. Instead of repeatedly writing to the same address, you cycle through a block of addresses. The Flash EEPROM component mentioned earlier does this automatically. For standard EEPROM, you can implement a simple counter that increments an index, writes data, and wraps around. While more complex, it can extend the functional life of your device by orders of magnitude.
For complex data arrays or floating-point numbers, bypassing the graphical macros for a dedicated Flowcode C-code block is highly efficient. By utilizing C pointers and structures, you can stream entire data profiles into the EEPROM sequentially without building complex graphical loops. Each macro requires only an address (0 to
