sahilmgandhi | 18:6a4db94011d3 | 13 | ##### How to use this driver ##### |
sahilmgandhi | 18:6a4db94011d3 | 14 | ============================================================================== |
sahilmgandhi | 18:6a4db94011d3 | 15 | [..] |
sahilmgandhi | 18:6a4db94011d3 | 16 | This driver is a generic layered driver which contains a set of APIs used to |
sahilmgandhi | 18:6a4db94011d3 | 17 | control SRAM memories. It uses the FSMC layer functions to interface |
sahilmgandhi | 18:6a4db94011d3 | 18 | with SRAM devices. |
sahilmgandhi | 18:6a4db94011d3 | 19 | The following sequence should be followed to configure the FSMC to interface |
sahilmgandhi | 18:6a4db94011d3 | 20 | with SRAM/PSRAM memories: |
sahilmgandhi | 18:6a4db94011d3 | 21 | |
sahilmgandhi | 18:6a4db94011d3 | 22 | (#) Declare a SRAM_HandleTypeDef handle structure, for example: |
sahilmgandhi | 18:6a4db94011d3 | 23 | SRAM_HandleTypeDef hsram; and: |
sahilmgandhi | 18:6a4db94011d3 | 24 | |
sahilmgandhi | 18:6a4db94011d3 | 25 | (++) Fill the SRAM_HandleTypeDef handle "Init" field with the allowed |
sahilmgandhi | 18:6a4db94011d3 | 26 | values of the structure member. |
sahilmgandhi | 18:6a4db94011d3 | 27 | |
sahilmgandhi | 18:6a4db94011d3 | 28 | (++) Fill the SRAM_HandleTypeDef handle "Instance" field with a predefined |
sahilmgandhi | 18:6a4db94011d3 | 29 | base register instance for NOR or SRAM device |
sahilmgandhi | 18:6a4db94011d3 | 30 | |
sahilmgandhi | 18:6a4db94011d3 | 31 | (++) Fill the SRAM_HandleTypeDef handle "Extended" field with a predefined |
sahilmgandhi | 18:6a4db94011d3 | 32 | base register instance for NOR or SRAM extended mode |
sahilmgandhi | 18:6a4db94011d3 | 33 | |
sahilmgandhi | 18:6a4db94011d3 | 34 | (#) Declare two FSMC_NORSRAM_TimingTypeDef structures, for both normal and extended |
sahilmgandhi | 18:6a4db94011d3 | 35 | mode timings; for example: |
sahilmgandhi | 18:6a4db94011d3 | 36 | FSMC_NORSRAM_TimingTypeDef Timing and FSMC_NORSRAM_TimingTypeDef ExTiming; |
sahilmgandhi | 18:6a4db94011d3 | 37 | and fill its fields with the allowed values of the structure member. |
sahilmgandhi | 18:6a4db94011d3 | 38 | |
sahilmgandhi | 18:6a4db94011d3 | 39 | (#) Initialize the SRAM Controller by calling the function HAL_SRAM_Init(). This function |
sahilmgandhi | 18:6a4db94011d3 | 40 | performs the following sequence: |
sahilmgandhi | 18:6a4db94011d3 | 41 | |
sahilmgandhi | 18:6a4db94011d3 | 42 | (##) MSP hardware layer configuration using the function HAL_SRAM_MspInit() |
sahilmgandhi | 18:6a4db94011d3 | 43 | (##) Control register configuration using the FSMC NORSRAM interface function |
sahilmgandhi | 18:6a4db94011d3 | 44 | FSMC_NORSRAM_Init() |
sahilmgandhi | 18:6a4db94011d3 | 45 | (##) Timing register configuration using the FSMC NORSRAM interface function |
sahilmgandhi | 18:6a4db94011d3 | 46 | FSMC_NORSRAM_Timing_Init() |
sahilmgandhi | 18:6a4db94011d3 | 47 | (##) Extended mode Timing register configuration using the FSMC NORSRAM interface function |
sahilmgandhi | 18:6a4db94011d3 | 48 | FSMC_NORSRAM_Extended_Timing_Init() |
sahilmgandhi | 18:6a4db94011d3 | 49 | (##) Enable the SRAM device using the macro __FSMC_NORSRAM_ENABLE() |
sahilmgandhi | 18:6a4db94011d3 | 50 | |
sahilmgandhi | 18:6a4db94011d3 | 51 | (#) At this stage you can perform read/write accesses from/to the memory connected |
sahilmgandhi | 18:6a4db94011d3 | 52 | to the NOR/SRAM Bank. You can perform either polling or DMA transfer using the |
sahilmgandhi | 18:6a4db94011d3 | 53 | following APIs: |
sahilmgandhi | 18:6a4db94011d3 | 54 | (++) HAL_SRAM_Read()/HAL_SRAM_Write() for polling read/write access |
sahilmgandhi | 18:6a4db94011d3 | 55 | (++) HAL_SRAM_Read_DMA()/HAL_SRAM_Write_DMA() for DMA read/write transfer |
sahilmgandhi | 18:6a4db94011d3 | 56 | |
sahilmgandhi | 18:6a4db94011d3 | 57 | (#) You can also control the SRAM device by calling the control APIs HAL_SRAM_WriteOperation_Enable()/ |
sahilmgandhi | 18:6a4db94011d3 | 58 | HAL_SRAM_WriteOperation_Disable() to respectively enable/disable the SRAM write operation |
sahilmgandhi | 18:6a4db94011d3 | 59 | |
sahilmgandhi | 18:6a4db94011d3 | 60 | (#) You can continuously monitor the SRAM device HAL state by calling the function |
sahilmgandhi | 18:6a4db94011d3 | 61 | HAL_SRAM_GetState() |
