uint16_t data = 0xABCD; EE_WriteVariable(0x0001, data); // Store at virtual address 0x0001
Example for STM32F4:
uint16_t readData; EE_ReadVariable(0x0001, &readData); x-cube-eeprom github
if(readData == data) { printf("EEPROM works like a charm!\r\n"); }
Whether you're building a smart thermostat or a custom flight controller, give this library a try. Your future self—debugging a corrupted configuration at 2 AM—will thank you. You could use the internal Flash, but that
If you haven't stumbled across this GitHub gem yet, you’re in for a treat. This repository provides a hardware-agnostic, lightweight abstraction layer for managing EEPROM (or Flash emulated as EEPROM) on STM32 microcontrollers.
Every embedded developer knows the struggle. You have sensor calibration data, device settings, or a transaction log that needs to survive a power cycle. You could use the internal Flash, but that often involves complex unlock sequences, page erases, and the risk of bricking your firmware if you overwrite the wrong sector. You could use the internal Flash
/* Specify the memory areas */ MEMORY { FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 1024K EEPROM (rx) : ORIGIN = 0x08080000, LENGTH = 64K RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K } #include "eeprom.h" int main(void) { HAL_Init(); EE_Init();
Let’s dive into why this library deserves a spot in your toolchain. The x-cube-eeprom repository (hosted on GitHub under STMicroelectronics or community forks) is an expansion software pack designed to simplify non-volatile data storage. While the name suggests a physical EEPROM driver, the core logic often focuses on EEPROM Emulation .
