Flowcode’s rich ecosystem of EEPROM components—onboard, I²C, SPI, Flash emulation, and One‑Wire—covers virtually every need. With the techniques outlined in this guide, you are now equipped to harness the full power of non‑volatile memory in your next project.
Double-check that you are not accidentally mapping a 16-bit signed integer into a component macro that expects an 8-bit unsigned character byte.
Even more practically, the EEStrings.fcfx example shows how to store and retrieve strings. This is essential for applications like saving user-entered names, configuration profiles, or short log messages.
Flowcode perfectly simulates EEPROM reads and writes on your PC screen. However, if your hardware fails to preserve data, ensure your compilation Config Bits are not set to "Clear EEPROM on Program" via your ICSP programmer tools. Conclusion flowcode eeprom exclusive
// Write a new value cyclically EEPROM1::WriteByte(currentAddress, sensorValue) currentAddress = currentAddress + 1 if currentAddress > maxAddress then currentAddress = 0 end if
Unlike standard "ReadByte" and "WriteByte" functions, the exclusive component offers:
You then write v2 to EEPROM address 0 and v3 to address 1. When reading, you multiply v2 by 100 and add v3 to reconstruct the original 10‑bit number. Even more practically, the EEStrings
Flowcode supports a wide range of microcontroller families, including PIC, AVR, ARM, and dsPIC, as well as platforms like Arduino and Raspberry Pi. This cross‑platform flexibility makes it an excellent choice for both educational settings and professional development.
Ideal for configuration flags and small settings.
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. However, if your hardware fails to preserve data,
The keyword represents a leap forward in abstraction. For professional engineers, it reduces development time for persistent storage by nearly 70%. For students and hobbyists, it demystifies non-volatile memory, allowing them to focus on application logic rather than bit-banging.
