// Increment address by 2 for the next reading address = address + 2

Writing data exclusively means ensuring that no other interrupt or background process can interrupt the memory modification cycle. Microcontroller EEPROM hardware requires a specific timing sequence to lock in a byte.

that allows users to read and write data directly to a microcontroller’s onboard non-volatile memory. Unlike RAM, which loses data when power is removed, EEPROM preserves information such as calibration settings or sensor logs. www.flowcode.co.uk Key Features and Functionality Simulation Support:

As a Flowcode user, migrating projects to a new version demands attention. A notable change involves the EEPROM.Read() macro. As one developer noted: "In Flowcode 8, I used EEPROM.Read() to retrieve a single byte of data without issues. In Flowcode 10, however, EEPROM.Read() appears to handle both 8- and 16-bit reads, so I switched to EEPROM.ReadByte() to ensure only a single byte is read". When migrating, you must carefully audit your EEPROM read operations and decide whether to use the new ReadByte() for single-byte reads or adapt your logic to handle potential 16-bit returns from Read() .

Not all microcontrollers have dedicated EEPROM hardware. For those that do not, Flowcode offers the component, which emulates EEPROM using the device’s Flash program memory. The trade‑off is that Flash memory has a much lower write endurance (typically 10,000–100,000 cycles compared to 1,000,000 cycles for true EEPROM). Nevertheless, this feature is a lifesaver when you need persistence on low‑cost chips.

In Flowcode, the EEPROM component provides a structured interface for reading from and writing to this onboard memory. The component is fully functional within Flowcode's simulation environment, allowing you to test your code without hardware. However, for compilation to succeed, the target microcontroller must physically possess EEPROM memory. Unlike RAM, which loses data when power is

Instead of overwriting a single address, create a rolling structure across your available memory space:

Why is this question so important? Because many microcontrollers and EEPROM chips are designed to handle 8‑bit bytes as their fundamental storage unit. However, real‑world data often comes in larger sizes: for instance, an analog‑to‑digital converter (ADC) might produce a 10‑bit value (0–1023). If you try to write that 10‑bit number directly into an 8‑bit EEPROM location, the upper bits will be truncated or corrupted.

: Specialized ReadString and WriteString macros allow for the storage and retrieval of text, automatically managing the necessary memory locations. Practical Applications

To guarantee exclusive access, wrap your write macros in atomic code blocks. Disable global interrupts right before calling the Flowcode EEPROM write component, then re-enable them immediately after. This structure guarantees that your critical system variables update fully without partial corruption from conflicting background tasks.
