******************************************************************************
* @file stm32746g_discovery_sdram.c
* @author MCD Application Team
* @brief This file includes the SDRAM driver for the MT48LC4M32B2B5-7 memory
* device mounted on STM32746G-Discovery board.
@verbatim
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.

* @file stm32746g_discovery_ts.c
* @author MCD Application Team
* @brief This file provides a set of functions needed to manage the Touch
* Screen on STM32746G-Discovery board.
@verbatim
1. How To use this driver:
--------------------------
- This driver is used to drive the touch screen module of the STM32746G-Discovery
board on the RK043FN48H-CT672B 480x272 LCD screen with capacitive touch screen.
- The FT5336 component driver must be included in project files according to
the touch screen driver present on this board.
2. Driver description:
---------------------
+ Initialization steps:
o Initialize the TS module using the BSP_TS_Init() function. This
function includes the MSP layer hardware resources initialization and the
communication layer configuration to start the TS use. The LCD size properties
(x and y) are passed as parameters.
o If TS interrupt mode is desired, you must configure the TS interrupt mode
by calling the function BSP_TS_ITConfig(). The TS interrupt mode is generated
as an external interrupt whenever a touch is detected.
The interrupt mode internally uses the IO functionalities driver driven by
the IO expander, to configure the IT line.
+ Touch screen use
o The touch screen state is captured whenever the function BSP_TS_GetState() is
used. This function returns information about the last LCD touch occurred
in the TS_StateTypeDef structure.
o If TS interrupt mode is used, the function BSP_TS_ITGetStatus() is needed to get
the interrupt status. To clear the IT pending bits, you should call the
function BSP_TS_ITClear().
o The IT is handled using the corresponding external interrupt IRQ handler,
the user IT callback treatment is implemented on the same external interrupt
callback.

;* File Name : startup_stm32f746xx.s

;* Description : STM32F746xx devices vector table for MDK-ARM toolchain.
;* This module performs:
;* - Set the initial SP
;* - Set the initial PC == Reset_Handler
;* - Set the vector table entries with the exceptions ISR address
;* - Branches to __main in the C library (which eventually
;* calls main()).
;* After Reset the CortexM7 processor is in Thread mode,
;* priority is Privileged, and the Stack is set to Main.
