-@par Example Description
-
-This example provides a basic example of how to use the SDIO firmware library and
-an associate driver to perform read/write operations on the SD Card memory (SD Card
-V1.0, V1.1, V2.0 and SDHC (High Capacity) protocol)that could be mounted on the
-STM3210E-EVAL board.
-
-The example provides different SD Card transfer states and operations and here
-below a description of each step:
- - First the SDIO peripheral and SD Card are initialized using the SD_Init()
- function:
- - Configure the SDIO according to the desired SDIO_CK clock frequency.
- - Reset the SD Card
- - Identify the SD Card
- - Initializes the SD Card
- - Get the SD Card Info
- - Select the SD Card
- - Enable the Wide Bus mode (4-bit data)
-
- - SD Card Erase Operation
- - Starts an Erase operation: Erase the corresponding blocks using
- the SD_Erase() function
- - Read the Erased blocks using the SD_ReadMultiBlocks() function
- - Test if the corresponding Blocks are well erased: check if the
- EraseStatus variable is equal to PASSED. If the erase operation is
- passed LED1 is turned ON.
-
- - SD Card Single Block Operation
- - Starts a Write operation: Write a single Block using the SD_WriteBlock()
- function
- - Read a single Block using the SD_ReadBlock() function
- - Compare the written Block and the read one: check if the TransferStatus1
- variable is equal to PASSED. If the Single Block Read/write operation
- is passed LED2 is turned ON.
-
- - SD Card Multiple Block Operation
- - Starts a Multiple Write operation: Write a multi Blocks using the
- SD_WriteMultiBlocks() function.
- - Read a multiple Blocks using the SD_ReadMultiBlocks() function
- - Compare the written Blocks and the read one: check if the TransferStatus2
- variable is equal to PASSED. If the Multiple Blocks Read/Write operation
- is passed LED3 is turned ON.
-
-All data transfers are made by DMA.
-At each operation, the SD Card presence and status is checked using the SD_GetStatus()
-function and a global variable "Status" storing the results of the last operation.
-
-SD Card Operations and Written/Read data correctness is signaled by LED
-lightening and though as follow:
- - If the Erase operation is PASSED then LED1 ON else the LED4 is ON and LED1 is OFF
- - If the Single Block Write/Read operation is PASSED then LED2 ON else the LED4 is ON and LED2 is OFF
- - If the Multi Blocks Write/Read operation is PASSED then LED3 ON else the LED4 is ON and LED3 is OFF
- - Any SD Card operation including the SD Initialization error is signaled by
- LED4 ON.

-@par Hardware and Software environment
-
- - This example runs only on STM32F10x High-Density and XL-Density Devices.
-
- - This example has been tested with STMicroelectronics STM3210E-EVAL (High-Density
- and XL-Density) evaluation board and can be easily tailored to any other
- supported device and development board.
-
-@note Make sure that the Jumper 17 (JP17) is closed and Jumper 20 (JP20) is open
- in STM3210E-EVAL
-
-
-@par How to use it ?
-
-In order to make the program work, you must do the following :
- - Copy all source files from this example folder to the template folder under
- Project\STM32F10x_StdPeriph_Template
- - Open your preferred toolchain
- - Rebuild all files and load your image into target memory
- - Run the example
-
-@note
- - Low-density Value line devices are STM32F100xx microcontrollers where the
- Flash memory density ranges between 16 and 32 Kbytes.
- - Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx
- microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes.
- - Medium-density Value line devices are STM32F100xx microcontrollers where
- the Flash memory density ranges between 64 and 128 Kbytes.
- - Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx
- microcontrollers where the Flash memory density ranges between 64 and 128 Kbytes.
- - High-density Value line devices are STM32F100xx microcontrollers where
- the Flash memory density ranges between 256 and 512 Kbytes.
- - High-density devices are STM32F101xx and STM32F103xx microcontrollers where
- the Flash memory density ranges between 256 and 512 Kbytes.
- - XL-density devices are STM32F101xx and STM32F103xx microcontrollers where
- the Flash memory density ranges between 512 and 1024 Kbytes.
- - Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers.
