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.
Below is a description of the different example steps:
  - 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)
  - Erase the correponding blocks
  - Read the Erased blocks
  - Test if the corresponding Blocks are well erased: check if the EraseStatus 
    variable is equal to PASSED.
  - Set the Data Transfer Mode to DMA   
  - Write a single Block             
  - Read a single Block
  - Comapare the written Block and the read one: check if the TransferStatus1 
    variable is equal to PASSED.
  - Write multiple Blocks (2)             
  - Read multiple Blocks (2)
  - Comapare the written Blocks and the read one: check if the TransferStatus2 
    variable is equal to PASSED.

Hardware and Software environment 

  - This example runs only on STM32F10x High-Density Devices.
  
  - This example has been tested with STMicroelectronics STM3210E-EVAL (STM32F10x 
    High-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 

How to use it ? 

In order to make the program work, you must do the following:
- Create a project and setup all project configuration
- Add the required Library files:
  - stm32f10x_gpio.c 
  - stm32f10x_rcc.c 
  - misc.c 
  - stm32f10x_sdio.c 
  - stm32f10x_dma.c
  - system_stm32f10x.c (under Libraries\CMSIS\Core\CM3)
      
- Edit stm32f10x.h file to select the device you are working on (#define 
  STM32F10X_HD, in this case).
  
Tip: You can tailor the provided project template to run this example, for 
        more details please refer to "stm32f10x_stdperiph_lib_um.chm" user 
        manual; select "Peripheral Examples" then follow the instructions 
        provided in "How to proceed" section.   
- Link all compiled files and load your image into target memory
- Run the example

note
 - Low-density devices are STM32F101xx and STM32F103xx microcontrollers where
   the Flash memory density ranges between 16 and 32 Kbytes.
 - Medium-density devices are STM32F101xx and STM32F103xx microcontrollers where
   the Flash memory density ranges between 32 and 128 Kbytes.
 - High-density devices are STM32F101xx and STM32F103xx microcontrollers where
   the Flash memory density ranges between 256 and 512 Kbytes.
 - Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers.
