Example Description

This example provides a description of how to program the STM32F0xx FLASH.

After Reset, the Flash memory Program/Erase Controller is locked. To unlock it, the FLASH_Unlock function is used. Before programming the desired addresses, an erase operation is performed using the flash erase page feature. The erase procedure starts with the calculation of the number of pages to be used. Then all these pages will be erased one by one by calling FLASH_ErasePage function.

Once this operation is finished, the programming operation will be performed by using the FLASH_ProgramWord function. The written data is then checked and the result of the programming operation is stored into the MemoryProgramStatus variable.

Directory contents

• FLASH/FLASH_Program/stm32f0xx_conf.h Library Configuration file
• FLASH/FLASH_Program/stm32f0xx_it.c Interrupt handlers
• FLASH/FLASH_Program/stm32f0xx_it.h Interrupt handlers header file
• FLASH/FLASH_Program/main.c Main program
• FLASH/FLASH_Program/main.h Main program header file
• FLASH/FLASH_Program/system_stm32f0xx.c STM32F0xx system source file

Note:

The "system_stm32f0xx.c" is generated by an automatic clock configuration tool and can be easily customized to meet user application requirements. To select different clock setup, use the "STM32F0xx_Clock_Configuration_VX.Y.Z.xls" provided with the AN4055 package available on ST Microcontrollers

Hardware and Software environment

• This example runs on STM32F0xx Devices.

• This example has been tested with STMicroelectronics STM320518-EVAL and STM32072B-EVAL including respectively STM32F051R8T6 and STM32F072VBT6 devices and can be easily tailored to any other supported device and development board
