The Read macro requires a specific target memory address and returns the byte stored at that location. Address (Integer/Byte) Return: Data (Byte) The Write Macro The Write macro sends a byte of data to a specific address. Input: Address (Integer/Byte), Data (Byte)
Flowcode treats EEPROM as a dedicated peripheral component. Instead of writing raw C code to manipulate specialized registers (like EECON1 or EEDATA in PIC microcontrollers), Flowcode uses a standard, unified component interface. Memory Addressing and Layout
Flowcode's exclusive simulation environment includes a powerful debugging tool: the . You can view the contents of the emulated EEPROM in real-time by navigating to View -> Consoles and then selecting the EEPROM tab . This allows you to verify writes, check for unintended modifications, and confirm data persistence across simulation restarts. flowcode eeprom exclusive
To bypass this limitation, you must implement bit-shifting algorithms to break large data types down into byte-sized chunks, and then reassemble them during the read cycle. Saving 16-Bit Integer Values
Repeatedly writing the same value to an EEPROM address shortens its lifespan. An exclusive update routine reads the existing byte first, compares it to the new byte, and only executes a write macro if the data has changed. This simple logical gate extends device longevity exponentially. 2. Handling Multi-Byte Data Types The Read macro requires a specific target memory
2. Exclusive Optimization: Overcoming the Endurance Bottleneck
A killer feature of the Exclusive component is the ability to retain EEPROM data during a microcontroller reprogramming. In standard workflows, flashing a new HEX file often erases the EEPROM. The Flowcode Exclusive linker script allows you to check a box in the Project Options: "Preserve EEPROM Contents." This is vital for field-updated devices that must retain calibration data. Instead of writing raw C code to manipulate
Upon system boot, read Address 0 . If it does not equal 0xAA , your system knows the last write operation was interrupted by a power failure, allowing you to trigger a safe factory reset routine. Enabling Hardware Brown-Out Reset (BOR)
Note: According to Flowcode support forums , when designing high-cycle write applications (like data logging), it is important to minimize write operations, as EEPROM has a limited number of write cycles (typically 100,000 to 1,000,000). Conclusion: Why Choose Flowcode for EEPROM?
