Flowcode Eeprom Exclusive: New!

The properties panel allows you to define initial values for your EEPROM cells at compilation time. This is highly useful for storing factory calibration constants or default system settings. Enter these values as a comma-separated list in the property box. When the microcontroller is flashed, these addresses are pre-populated automatically. Exclusive Pattern 1: Conditional "Change-Only" Writes

Flowcode provides for reading and writing to EEPROM (Electrically Erasable Programmable Read-Only Memory) on supported microcontrollers. These components allow non-volatile data storage that persists after power loss — ideal for saving configuration settings, calibration values, or user data. flowcode eeprom exclusive

from the "Storage" menu. Its exclusive benefit is providing a common interface that works across different microcontrollers (PIC, AVR, ARM) without you needing to know the specific hardware addresses. 2. Saving Critical Data Your flowchart uses a Component Macro The properties panel allows you to define initial

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. When the microcontroller is flashed, these addresses are

If you try to write a number greater than 255 to a single EEPROM location, you will lose data. The value will be truncated, and only the lower 8 bits will be stored. This is why understanding “exclusive” byte‑level handling is essential.

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

Specify the total bytes available (e.g., 256 bytes for standard PIC16 chips).
