bogdanm | 0:9b334a45a8ff | 12 | ============================================================================== |
bogdanm | 0:9b334a45a8ff | 13 | ##### How to use this driver ##### |
bogdanm | 0:9b334a45a8ff | 14 | ============================================================================== |
bogdanm | 0:9b334a45a8ff | 15 | [..] |
bogdanm | 0:9b334a45a8ff | 16 | This driver is a generic layered driver which contains a set of APIs used to |
bogdanm | 0:9b334a45a8ff | 17 | control SRAM memories. It uses the FMC layer functions to interface |
bogdanm | 0:9b334a45a8ff | 18 | with SRAM devices. |
bogdanm | 0:9b334a45a8ff | 19 | The following sequence should be followed to configure the FMC to interface |
bogdanm | 0:9b334a45a8ff | 20 | with SRAM/PSRAM memories: |
bogdanm | 0:9b334a45a8ff | 21 | |
bogdanm | 0:9b334a45a8ff | 22 | (#) Declare a SRAM_HandleTypeDef handle structure, for example: |
bogdanm | 0:9b334a45a8ff | 23 | SRAM_HandleTypeDef hsram; and: |
bogdanm | 0:9b334a45a8ff | 24 | |
bogdanm | 0:9b334a45a8ff | 25 | (++) Fill the SRAM_HandleTypeDef handle "Init" field with the allowed |
bogdanm | 0:9b334a45a8ff | 26 | values of the structure member. |
bogdanm | 0:9b334a45a8ff | 27 | |
bogdanm | 0:9b334a45a8ff | 28 | (++) Fill the SRAM_HandleTypeDef handle "Instance" field with a predefined |
bogdanm | 0:9b334a45a8ff | 29 | base register instance for NOR or SRAM device |
bogdanm | 0:9b334a45a8ff | 30 | |
bogdanm | 0:9b334a45a8ff | 31 | (++) Fill the SRAM_HandleTypeDef handle "Extended" field with a predefined |
bogdanm | 0:9b334a45a8ff | 32 | base register instance for NOR or SRAM extended mode |
bogdanm | 0:9b334a45a8ff | 33 | |
bogdanm | 0:9b334a45a8ff | 34 | (#) Declare two FMC_NORSRAM_TimingTypeDef structures, for both normal and extended |
bogdanm | 0:9b334a45a8ff | 35 | mode timings; for example: |
bogdanm | 0:9b334a45a8ff | 36 | FMC_NORSRAM_TimingTypeDef Timing and FMC_NORSRAM_TimingTypeDef ExTiming; |
bogdanm | 0:9b334a45a8ff | 37 | and fill its fields with the allowed values of the structure member. |
bogdanm | 0:9b334a45a8ff | 38 | |
bogdanm | 0:9b334a45a8ff | 39 | (#) Initialize the SRAM Controller by calling the function HAL_SRAM_Init(). This function |
bogdanm | 0:9b334a45a8ff | 40 | performs the following sequence: |
bogdanm | 0:9b334a45a8ff | 41 | |
bogdanm | 0:9b334a45a8ff | 42 | (##) MSP hardware layer configuration using the function HAL_SRAM_MspInit() |
bogdanm | 0:9b334a45a8ff | 43 | (##) Control register configuration using the FMC NORSRAM interface function |
bogdanm | 0:9b334a45a8ff | 44 | FMC_NORSRAM_Init() |
bogdanm | 0:9b334a45a8ff | 45 | (##) Timing register configuration using the FMC NORSRAM interface function |
bogdanm | 0:9b334a45a8ff | 46 | FMC_NORSRAM_Timing_Init() |
bogdanm | 0:9b334a45a8ff | 47 | (##) Extended mode Timing register configuration using the FMC NORSRAM interface function |
bogdanm | 0:9b334a45a8ff | 48 | FMC_NORSRAM_Extended_Timing_Init() |
bogdanm | 0:9b334a45a8ff | 49 | (##) Enable the SRAM device using the macro __FMC_NORSRAM_ENABLE() |
bogdanm | 0:9b334a45a8ff | 50 | |
bogdanm | 0:9b334a45a8ff | 51 | (#) At this stage you can perform read/write accesses from/to the memory connected |
bogdanm | 0:9b334a45a8ff | 52 | to the NOR/SRAM Bank. You can perform either polling or DMA transfer using the |
bogdanm | 0:9b334a45a8ff | 53 | following APIs: |
bogdanm | 0:9b334a45a8ff | 54 | (++) HAL_SRAM_Read()/HAL_SRAM_Write() for polling read/write access |
bogdanm | 0:9b334a45a8ff | 55 | (++) HAL_SRAM_Read_DMA()/HAL_SRAM_Write_DMA() for DMA read/write transfer |
bogdanm | 0:9b334a45a8ff | 56 | |
bogdanm | 0:9b334a45a8ff | 57 | (#) You can also control the SRAM device by calling the control APIs HAL_SRAM_WriteOperation_Enable()/ |
bogdanm | 0:9b334a45a8ff | 58 | HAL_SRAM_WriteOperation_Disable() to respectively enable/disable the SRAM write operation |
bogdanm | 0:9b334a45a8ff | 59 | |
bogdanm | 0:9b334a45a8ff | 60 | (#) You can continuously monitor the SRAM device HAL state by calling the function |
bogdanm | 0:9b334a45a8ff | 61 | HAL_SRAM_GetState() |
bogdanm | 0:9b334a45a8ff | 62 | |
