1. How To use this driver:
--------------------------
- This driver is used to drive the MT48LC4M32B2B5-7 SDRAM external memory mounted
on STM32746G-Discovery board.
- This driver does not need a specific component driver for the SDRAM device
to be included with.
2. Driver description:
---------------------
+ Initialization steps:
o Initialize the SDRAM external memory using the BSP_SDRAM_Init() function. This
function includes the MSP layer hardware resources initialization and the
FMC controller configuration to interface with the external SDRAM memory.
o It contains the SDRAM initialization sequence to program the SDRAM external
device using the function BSP_SDRAM_Initialization_sequence(). Note that this
sequence is standard for all SDRAM devices, but can include some differences
from a device to another. If it is the case, the right sequence should be
implemented separately.
+ SDRAM read/write operations
o SDRAM external memory can be accessed with read/write operations once it is
initialized.
Read/write operation can be performed with AHB access using the functions
BSP_SDRAM_ReadData()/BSP_SDRAM_WriteData(), or by DMA transfer using the functions
BSP_SDRAM_ReadData_DMA()/BSP_SDRAM_WriteData_DMA().
o The AHB access is performed with 32-bit width transaction, the DMA transfer
configuration is fixed at single (no burst) word transfer (see the
SDRAM_MspInit() static function).
o User can implement his own functions for read/write access with his desired
configurations.
o If interrupt mode is used for DMA transfer, the function BSP_SDRAM_DMA_IRQHandler()
is called in IRQ handler file, to serve the generated interrupt once the DMA
transfer is complete.
o You can send a command to the SDRAM device in runtime using the function
BSP_SDRAM_Sendcmd(), and giving the desired command as parameter chosen between
the predefined commands of the "FMC_SDRAM_CommandTypeDef" structure.
