+Example description

+===================

+This example provides a basic communication between USART1 (Synchronous mode) 

+and SPI1 using flags.

+

+First, the USART1 sends data from TxBuffer1 buffer to SPI1 using USART1 TXE flag.

+Data received, using RXNE flag, by SPI1 is stored in RxBuffer2 then compared with

+the sent ones and the result of this comparison is stored in the "TransferStatus1" 

+variable.

+ 

+Then, the SPI1 sends data from TxBuffer2 buffer to USART1 using SPI1 TXE flag.

+Data received, using RXNE flag, by USART1 is stored in RxBuffer1 then compared with

+the sent ones and the result of this comparison is stored in the "TransferStatus2" 

+variable.   

+

+

+USART1 configured as follow:

+  - BaudRate = 115200 baud  

+  - Word Length = 8 Bits

+  - One Stop Bit

+  - No parity

+  - Hardware flow control disabled (RTS and CTS signals)

+  - Receive and transmit enabled

+  - USART Clock enabled

+  - USART CPOL: Clock is active high

+  - USART CPHA: Data is captured on the second edge 

+  - USART LastBit: The clock pulse of the last data bit is output to the SCLK pin

+

+SPI1 configured as follow:

+  - Direction = 2 Lines FullDuplex

+  - Mode = Slave Mode

+  - DataSize = 8 Bits

+  - CPOL = Clock is active high

+  - CPHA = Data is captured on the second edge 

+  - NSS = NSS Software

+  - First Bit = First Bit is the LSB     

+

+Directory contents

+==================

+stm32f10x_conf.h  Library Configuration file

+stm32f10x_it.h    Interrupt handlers header file

+stm32f10x_it.c    Interrupt handlers

+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.

+There is no need for any modification when switching between these two boards.

+

+Connect USART1_Tx(PA.09) to SPI1_MOSI(PA.07), USART1_Rx(PA.10) to SPI1_MISO(PA.06)

+and USART1_CK(PA.08) to SPI1_SCK(PA.05).

+ 

+  

+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_usart.c

+  + stm32f10x_spi.c

+  + stm32f10x_nvic.c

+  + stm32f10x_flash.c    

+

+- Link all compiled files and load your image into target memory

+- Run the example
