Jerome Coutant 2:123b894b49dd 38 User NOTES
Jerome Coutant 2:123b894b49dd 39 1. How To use this driver:
Jerome Coutant 2:123b894b49dd 40 --------------------------
Jerome Coutant 2:123b894b49dd 41 - This driver is used to drive the MT48LC4M32B2B5-7 SDRAM external memory mounted
Jerome Coutant 2:123b894b49dd 42 on STM32469I-Discovery board.
Jerome Coutant 2:123b894b49dd 43 - This driver does not need a specific component driver for the SDRAM device
Jerome Coutant 2:123b894b49dd 44 to be included with.
Jerome Coutant 2:123b894b49dd 45
Jerome Coutant 2:123b894b49dd 46 2. Driver description:
Jerome Coutant 2:123b894b49dd 47 ---------------------
Jerome Coutant 2:123b894b49dd 48 + Initialization steps:
Jerome Coutant 2:123b894b49dd 49 o Initialize the SDRAM external memory using the BSP_SDRAM_Init() function. This
Jerome Coutant 2:123b894b49dd 50 function includes the MSP layer hardware resources initialization and the
Jerome Coutant 2:123b894b49dd 51 FMC controller configuration to interface with the external SDRAM memory.
Jerome Coutant 2:123b894b49dd 52 o It contains the SDRAM initialization sequence to program the SDRAM external
Jerome Coutant 2:123b894b49dd 53 device using the function BSP_SDRAM_Initialization_sequence(). Note that this
Jerome Coutant 2:123b894b49dd 54 sequence is standard for all SDRAM devices, but can include some differences
Jerome Coutant 2:123b894b49dd 55 from a device to another. If it is the case, the right sequence should be
Jerome Coutant 2:123b894b49dd 56 implemented separately.
Jerome Coutant 2:123b894b49dd 57
Jerome Coutant 2:123b894b49dd 58 + SDRAM read/write operations
Jerome Coutant 2:123b894b49dd 59 o SDRAM external memory can be accessed with read/write operations once it is
Jerome Coutant 2:123b894b49dd 60 initialized.
Jerome Coutant 2:123b894b49dd 61 Read/write operation can be performed with AHB access using the functions
Jerome Coutant 2:123b894b49dd 62 BSP_SDRAM_ReadData()/BSP_SDRAM_WriteData(), or by DMA transfer using the functions
Jerome Coutant 2:123b894b49dd 63 BSP_SDRAM_ReadData_DMA()/BSP_SDRAM_WriteData_DMA().
Jerome Coutant 2:123b894b49dd 64 o The AHB access is performed with 32-bit width transaction, the DMA transfer
Jerome Coutant 2:123b894b49dd 65 configuration is fixed at single (no burst) word transfer (see the
Jerome Coutant 2:123b894b49dd 66 BSP_SDRAM_MspInit() weak function).
Jerome Coutant 2:123b894b49dd 67 o User can implement his own functions for read/write access with his desired
Jerome Coutant 2:123b894b49dd 68 configurations.
Jerome Coutant 2:123b894b49dd 69 o If interrupt mode is used for DMA transfer, the function BSP_SDRAM_DMA_IRQHandler()
Jerome Coutant 2:123b894b49dd 70 is called in IRQ handler file, to serve the generated interrupt once the DMA
Jerome Coutant 2:123b894b49dd 71 transfer is complete.
Jerome Coutant 2:123b894b49dd 72 o You can send a command to the SDRAM device in runtime using the function
Jerome Coutant 2:123b894b49dd 73 BSP_SDRAM_Sendcmd(), and giving the desired command as parameter chosen between
Jerome Coutant 2:123b894b49dd 74 the predefined commands of the "FMC_SDRAM_CommandTypeDef" structure.
