| Macro | Description | |-------|-------------| | | Reads a value (8 or 16 bits depending on platform) from a specified EEPROM address | | Write | Writes a value (8 or 16 bits depending on platform) to a specified EEPROM address | | ReadByte | Explicitly reads a single byte (8 bits) from EEPROM—available in newer versions | | WriteByte | Explicitly writes a single byte to EEPROM—available in newer versions |
To guarantee data integrity, always append a validation checksum to your data packets.
In modern embedded systems, the Electrically Erasable Programmable Read-Only Memory (EEPROM) serves as the primary repository for configuration data, calibration constants, and state persistence. While Flowcode provides a simplified graphical interface for these operations, "exclusive" mastery of the EEPROM component requires a deep understanding of its timing, endurance, and memory mapping. 2. Component Architecture and Macro Logic Flowcode EEPROM component
Writing bytes one by one to an external EEPROM creates massive software delays due to the internal write-cycle pause required by the chip after every command. flowcode eeprom exclusive
// Reading from consecutive addresses HighByte = Call Component Macro: EEPROM::Read(0) LowByte = Call Component Macro: EEPROM::Read(1) // Reconstructing the 16-bit variable MyValue = (HighByte << 8) | LowByte Use code with caution. Advanced Strategies for Exclusive Data Protection

What do you need to store (Integers, Floats, Strings)? Does your project use interrupts or multiple loops ?
When you add the EEPROM component to your Flowcode dashboard, you must map it to the internal hardware EEPROM of your target chip. 2. Exclusive Implementation: Reading and Writing Data Types
One of Flowcode’s most helpful features for EEPROM development is the . To view the contents of EEPROM memory during simulation: Here are the most important ones:
Standard Flowcode components often compete for the same memory addresses automatically. When multiple graphical components or macros read and write to unmapped spaces, data corruption occurs.
To begin using EEPROM in Flowcode, simply click the in the Misc section of the Component toolbar to include the component into your flowchart. Once added, you can use component macros to call EEPROM‑related functions.
The EEPROM component provides several built‑in macros. Here are the most important ones:
