sahilmgandhi | 18:6a4db94011d3 | 18 | ============================================================================== |
sahilmgandhi | 18:6a4db94011d3 | 19 | [..] This driver provides functions to configure and program the FLASH memory |
sahilmgandhi | 18:6a4db94011d3 | 20 | of all STM32F2xx devices. It includes |
sahilmgandhi | 18:6a4db94011d3 | 21 | (#) FLASH Memory Erase functions: |
sahilmgandhi | 18:6a4db94011d3 | 22 | (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and |
sahilmgandhi | 18:6a4db94011d3 | 23 | HAL_FLASH_Lock() functions |
sahilmgandhi | 18:6a4db94011d3 | 24 | (++) Erase function: Erase sector, erase all sectors |
sahilmgandhi | 18:6a4db94011d3 | 25 | (++) There are two modes of erase : |
sahilmgandhi | 18:6a4db94011d3 | 26 | (+++) Polling Mode using HAL_FLASHEx_Erase() |
sahilmgandhi | 18:6a4db94011d3 | 27 | (+++) Interrupt Mode using HAL_FLASHEx_Erase_IT() |
sahilmgandhi | 18:6a4db94011d3 | 28 | |
sahilmgandhi | 18:6a4db94011d3 | 29 | (#) Option Bytes Programming functions: Use HAL_FLASHEx_OBProgram() to : |
sahilmgandhi | 18:6a4db94011d3 | 30 | (++) Set/Reset the write protection |
sahilmgandhi | 18:6a4db94011d3 | 31 | (++) Set the Read protection Level |
sahilmgandhi | 18:6a4db94011d3 | 32 | (++) Set the BOR level |
sahilmgandhi | 18:6a4db94011d3 | 33 | (++) Program the user Option Bytes |
