+Example description
+===================
+This example provides a description of how to use two DMA channels to transfer a
+word data buffer from Flash memory to external SRAM memory and to recuperate the written
+data from external SRAM to be stored in internal SRAM.
+DMA2 Channel5 is configured to transfer, word by word, the contents of a 32-word data
+buffer stored in Flash memory to the external SRAM memory interfaced by FSMC. The start
+of transfer is triggered by software. DMA2 Channel5 memory-to-memory transfer is enabled.
+Source and destination address incrementing is also enabled. The transfer is started by
+setting the Channel enable bit for DMA2 Channel5. A polling on the Transfer Complete flag
+is done to check the end of transfer. The DMA2 Channel5 Transfer complete flag is then cleared.
+DMA1 Channel3 is configured to transfer, byte by byte, the contents of the first 128Bytes
+of external SRAM to the internal SRAM memory. The start of transfer is triggered by software.
+DMA1 Channel3 memory-to-memory transfer is enabled. Source and destination address
+incrementing is also enabled. The transfer is started by setting the Channel enable bit for
+DMA1 Channel3. A polling on the Transfer Complete flag is done to check the end of transfer.
+the DMA1 Channel3 Transfer complete flag is then cleared.
+A comparison between the source and destination buffers is done to check that all data have been
+correctly transferred.

+==================
+stm32f10x_conf.h Library Configuration file
+stm32f10x_it.c Interrupt handlers
+stm32f10x_it.h Interrupt handlers header file
+main.c Main program
+fsmc_sram.c FSMC SRAM driver
+fsmc_sram.h Header for the fsmc_sram.c file

+
+Hardware environment
+====================
+This example runs on STMicroelectronics STM3210E-EVAL evaluation board and can be
+easily tailored to any other hardware (with high density devices only).
+
+
+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_dma.c
+ + stm32f10x_rcc.c
+ + stm32f10x_nvic.c
+ + stm32f10x_flash.c
+ + stm32f10x_fsmc.c
+ + stm32f10x_gpio.c
+
+- Link all compiled files and load your image into target memory
+- Run the example
