-@par Example Description
-
-This example provides a basic communication between USARTy (Synchronous mode)
-and SPIy using flags. USARTy and SPIy can be USART1 and SPI1 or USART2 and SPI3,
-depending on the STMicroelectronics EVAL board you are using.
-
-First, the USARTy sends data from TxBuffer1 buffer to SPIy using USARTy TXE flag.
-Data received, using RXNE flag, by SPIy is stored in RxBuffer2 then compared with
-the sent ones and the result of this comparison is stored in the "TransferStatus1"
-variable.
-
-Then, the SPIy sends data from TxBuffer2 buffer to USARTy using SPIy TXE flag.
-Data received, using RXNE flag, by USARTy is stored in RxBuffer1 then compared with
-the sent ones and the result of this comparison is stored in the "TransferStatus2"
-variable.
-
-USARTy 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
-
-SPIy 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

-@par Hardware and Software environment
-
- - This example runs on STM32F10x Connectivity line, High-Density, High-Density
- Value line, Medium-Density, XL-Density, Medium-Density Value line, Low-Density
- and Low-Density Value line Devices.
-
- - This example has been tested with STMicroelectronics STM32100E-EVAL (High-Density
- Value line), STM32100B-EVAL (Medium-Density Value line), STM3210E-EVAL
- (High-Density and XL-Density) and STM3210B-EVAL (Medium-Density) evaluation
- boards and can be easily tailored to any other supported device and development
- board.
- This example can't be tested with STM3210C-EVAL (Connectivity Line) evaluation
- board since the USART CK pins are already used by other on-board modules.
- To select the STMicroelectronics evaluation board used to run the example,
- uncomment the corresponding line in USART/Synchronous/platform_config.h file
-
- - STM32100E-EVAL Set-up
- - 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).
-
- - STM32100B-EVAL Set-up
- - 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).
-
- - STM3210E-EVAL Set-up
- - 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).
-
- - STM3210B-EVAL Set-up
- - 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).

-@par How to use it ?
-
-In order to make the program work, you must do the following :
- - Copy all source files from this example folder to the template folder under
- Project\STM32F10x_StdPeriph_Template
- - Open your preferred toolchain
- - Rebuild all files and load your image into target memory
- - Run the example
