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. @par Directory contents - SDIO/stm32f10x_conf.h Library Configuration file - SDIO/stm32f10x_it.c Interrupt handlers - SDIO/stm32f10x_it.h Header for stm32f10x_it.c - SDIO/sdcard.c SD Card Driver file - SDIO/sdcard.h Header for sdcard.c - SDIO/main.c Main program @par 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 @par 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). @b 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. * <h3><center>&copy; COPYRIGHT 2009 STMicroelectronics</center></h3> */
