-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
-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.
-
-
-Directory contents
-==================
-stm32f10x_conf.h Library Configuration file
-stm32f10x_it.c Interrupt handlers
-stm32f10x_it.h Header for stm32f10x_it.c
-sdcard.c SD Card Driver file
-sdcard.h Header for sdcard.c
-main.c Main program
-
-
-Hardware environment
-====================
-This example runs on STMicroelectronics STM3210E-EVAL evaluation board and can be
-easily tailored to any other hardware.
-
-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 your toolchain's start-up files
-- Compile the directory content files and required Library files:
- + stm32f10x_lib.c
- + stm32f10x_gpio.c
- + stm32f10x_rcc.c
- + stm32f10x_nvic.c
- + stm32f10x_flash.c
- + stm32f10x_sdio.c
- + stm32f10x_dma.c
-
-- Link all compiled files and load your image into either RAM or Flash
-- Run the example
