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.
