WebThis specifies that we wish to store the userConfig variable in the .user_data section and const makes sure the address of userConfig is kept static. Now, to write to this area of flash during runtime, you can use the stm32f4 stdlib or HAL flash driver. Webstorage of data updated with byte or word granularity during run time. Microcontrollers used in these systems are more often based on embedded Flash memory. To eliminate components, save PCB space and reduce system cost, the STM32F0xx Flash memory may be used instead of an external EEPROM for simultaneous code and data storage.
WebApr 13, 2024 · 2. Programming Procedure. Step 1: Contact Levetop for the MCU source code (based on STM32F103x), and program it to the MCU board. In the code, two buttons (KEY0 & KEY1) are designed to work as below: KEY0: Erase the flash chip. KEY1: Retrieve and print out the first 100 data bytes stored in the flash. Step 2: Connect the MCU board to LT768x ... WebJan 2, 2024 · The API is very similar to the well known Arduino EEPROM.h API but with two additional functions: EEPROM.isValid() returns true if data in the EEPROM is valid or, in other words, if the data has been written at least once, otherwise EEPROM data is "undefined" and the function returns false. EEPROM.commit() store the EEPROM data in flash. Use ...
