-Example description
-===================
-This example provides a description of how to use four DMA channels to transfer a
-data buffer from memory to SPI2 through SPI1 and a second data buffer from memory
-to SPI1 through SPI2 in ful-duplex mode.
-
-The NSS pins are configured by software to set SPI1 as master and SPI2 as slave.
-DMA1 Channel2 and Channel4 are configured to store, respectively, the data
-received by SPI1 into the SPI1_Buffer_Rx and the data received by SPI2 into the
-SPI2_Buffer_Rx.
-DMA1 Channel3 is configured to transfer data from the SPI1_Buffer_Tx to the
-SPI1_DR register for transmission to SPI2. DMA1 Channel5 is configured to transfer
-data from the SPI2_Buffer_Tx to the SPI2_DR register for transmission to SPI1.
-
-As soon as the two SPIs TxDMAEN and RxDMAEN bits are set in the SPI1_CR2 and
-SPI2_CR2 registers, DMA1 Channel3 and Channel5 start transmitting, respectively,
-the SPI1 and SPI2 Tx buffers at the same time. At the same moment, the data received
-on SPI1 and SPI2 are stored by DMA1 Channel2 and Channel4 to the SPI1 and SPI2
-Rx buffers, respectively.
-
-A polling on all Transfer complete flags are done for all used DMA channels to
-check the end of all DMA channels transfers. The last received data on SPI1 and
-SPI2 are the CRC values sent by each SPI to the other. The transmitted and received
-buffers are compared to check that all data have been correctly transferred.

-Directory contents
-==================
-stm32f10x_conf.h Library Configuration file
-stm32f10x_it.c Interrupt handlers
-stm32f10x_it.h Interrupt handlers header file
-main.c Main program
-
-
-Hardware environment
-====================
-This example runs on STMicroelectronics STM3210B-EVAL and STM3210E-EVAL evaluation
-boards and can be easily tailored to any other hardware.
-
- - Connect SPI1 SCK pin (PA.05) to SPI2 SCK pin (PB.13)
- - Connect SPI1 MISO pin (PA.06) to SPI2 MISO pin (PB.14)
- - Connect SPI1 MOSI pin (PA.07) to SPI2 MOSI pin (PB.15)
-
-Note: in STM3210E-EVAL board, the jumper 14 (USB Disconnect) must be set in
- position 1<->2 in order to not interfer with SPI2 MISO pin PB14.
-
-
-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_spi.c
- + stm32f10x_nvic.c
- + stm32f10x_gpio.c
- + stm32f10x_flash.c
-
-- Link all compiled files and load your image into target memory
-- Run the example
