// Write a new value cyclically EEPROM1::WriteByte(currentAddress, sensorValue) currentAddress = currentAddress + 1 if currentAddress > maxAddress then currentAddress = 0 end if
For security applications, the exclusive version allows you to define a "Protected Zone." You can mark address ranges 100-200 as Read-Only after an initial factory calibration. A standard EEPROM component cannot enforce this; the exclusive component includes runtime checking to prevent accidental writes to critical calibration zones.
Are you utilizing or an external I2C/SPI EEPROM chip ?
One of the most impressive features hidden inside the simulation environment is wear leveling . When simulating a project on your PC, Flowcode tracks how many times you write to a specific EEPROM location. It visually alerts you when you are approaching the endurance limit, a feature absent in basic compilers.
| Macro Name | Description | Parameters | | :--- | :--- | :--- | | | Reads a byte from the specified address. | Address (UINT) | | Write | Writes a byte to the specified address. | Address (UINT), Data (BYTE) | | GetByte | Retrieves a byte (alternative syntax). | Index (UINT) | | SetByte | Sets a byte (alternative syntax). | Index (UINT), Value (BYTE) |
Read(Address)
An integer consists of two bytes: the High Byte and the Low Byte. To store an integer, you must split it apart before writing, and combine it back together when reading. The Split-Byte Write Method Create an integer variable: my_data .
When you need to store numbers from 0 to 65,535 (or 0 to 32767 depending on signed/unsigned implementation), you can split the value across two EEPROM locations:
The true power of the EEPROM component lies in its configurable properties:
If you’ve searched for “Flowcode EEPROM exclusive,” you’ve likely encountered a recurring question in embedded programming forums: How do I write data to EEPROM exclusively as 8‑bit bytes, even when my application works with larger numeric values?
Flowcode treats EEPROM through dedicated component libraries. Depending on your hardware architecture (PIC, AVR, Arduino, or ARM), you will interface with either internal or external storage.
Reading is non-destructive and fast.
: A simple boolean variable. If Storage_Busy was true, the rest of the program had to wait.
The official EEPROM component (EEPROM) in Flowcode is not a monolithic black box. It features several exclusive properties and macros that offer fine-grained control, setting it apart from simpler implementations.
The keyword phrase “flowcode eeprom exclusive” points to a specific and important nuance in embedded programming: . This concept arises from a real‑world forum discussion where a developer using Flowcode with a Matrix MIAC industrial controller asked:
