It uses the FMC layer functions to interface - with SRAM devices. - The following sequence should be followed to configure the FMC/FSMC to interface - with SRAM/PSRAM memories: - - (#) Declare a SRAM_HandleTypeDef handle structure, for example: - SRAM_HandleTypeDef hsram; and: - - (++) Fill the SRAM_HandleTypeDef handle "Init" field with the allowed - values of the structure member. - - (++) Fill the SRAM_HandleTypeDef handle "Instance" field with a predefined - base register instance for NOR or SRAM device - - (++) Fill the SRAM_HandleTypeDef handle "Extended" field with a predefined - base register instance for NOR or SRAM extended mode - - (#) Declare two FMC_NORSRAM_TimingTypeDef structures, for both normal and extended - mode timings; for example: - FMC_NORSRAM_TimingTypeDef Timing and FMC_NORSRAM_TimingTypeDef ExTiming; - and fill its fields with the allowed values of the structure member. - - (#) Initialize the SRAM Controller by calling the function HAL_SRAM_Init(). This function - performs the following sequence: - - (##) MSP hardware layer configuration using the function HAL_SRAM_MspInit() - (##) Control register configuration using the FMC NORSRAM interface function - FMC_NORSRAM_Init() - (##) Timing register configuration using the FMC NORSRAM interface function - FMC_NORSRAM_Timing_Init() - (##) Extended mode Timing register configuration using the FMC NORSRAM interface function - FMC_NORSRAM_Extended_Timing_Init() - (##) Enable the SRAM device using the macro __FMC_NORSRAM_ENABLE() - - (#) At this stage you can perform read/write accesses from/to the memory connected - to the NOR/SRAM Bank. You can perform either polling or DMA transfer using the - following APIs: - (++) HAL_SRAM_Read()/HAL_SRAM_Write() for polling read/write access - (++) HAL_SRAM_Read_DMA()/HAL_SRAM_Write_DMA() for DMA read/write transfer - - (#) You can also control the SRAM device by calling the control APIs HAL_SRAM_WriteOperation_Enable()/ - HAL_SRAM_WriteOperation_Disable() to respectively enable/disable the SRAM write operation - - (#) You can continuously monitor the SRAM device HAL state by calling the function - HAL_SRAM_GetState() - - @endverbatim - ****************************************************************************** - * @attention - * - * <h2><center>© COPYRIGHT(c) 2015 STMicroelectronics</center></h2> - * - * Redistribution and use in source and binary forms, with or without modification, - * are permitted provided that the following conditions are met: - * 1.
