A test -on RxNE flag is done for both master and slave to check the reception of data on -their respective data register. The same procedure is done for the remaining data -to transfer except the last ones. - -Last data from SPI1_Buffer_Tx is transmitted followed by enabling CRC transmission -for SPI1 and the last data from SPI2_Buffer_Tx is transmitted followed by enabling -CRC transmission for SPI2: user must take care to reduce code on this phase for -high speed communication. - -Last transmitted buffer data and CRC value are then received successively on -master and slave data registers. The received CRC value are stored on CRC1Value -and CRC2Value respectively for SPI1 and SPI2. - -Once the transfer is completed a comparison is done and TransferStatus1 and -TransferStatus2 gives the data transfer status for each data transfer direction -where it is PASSED if transmitted and received data are the same otherwise it -is FAILED. -A check of CRC error flag, for the master and the salve, is done after receiving -CRC data. - -@par Directory contents - - - SPI/CRC/stm32f10x_conf.h Library Configuration file - - SPI/CRC/stm32f10x_it.c Interrupt handlers - - SPI/CRC/stm32f10x_it.h Header for stm32f10x_it.c - - SPI/CRC/main.c Main program - - SPI/CRC/system_stm32f10x.c STM32F10x system source file - -@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(STM32F10x Medium-Density Value line), STM3210E-EVAL - (STM32F10x High-Density) and STM3210B-EVAL (STM32F10x Medium-Density) - evaluation boards and can be easily tailored to any other supported - device and development board. - This example can't be tested with STMicroelectronics STM3210C-EVAL (STM32F10x - Connectivity Line) evaluation board. - - - STM32100E-EVAL Set-up - - Connect SPI1 SCK (PA.05) pin to SPI2 SCK (PB.13) pin - - Connect SPI1 MISO (PA.06) pin to SPI2 MISO (PB.14) pin - - Connect SPI1 MOSI (PA.07) pin to SPI2 MOSI (PB.15) pin - - - STM32100B-EVAL Set-up - - Connect SPI1 SCK (PA.05) pin to SPI2 SCK (PB.13) pin - - Connect SPI1 MISO (PA.06) pin to SPI2 MISO (PB.14) pin - - Connect SPI1 MOSI (PA.07) pin to SPI2 MOSI (PB.15) pin - - - STM3210E-EVAL Set-up - - Connect SPI1 SCK (PA.05) pin to SPI2 SCK (PB.13) pin - - Connect SPI1 MISO (PA.06) pin to SPI2 MISO (PB.14) pin - - Connect SPI1 MOSI (PA.07) pin to SPI2 MOSI (PB.15) pin - @note The jumper 14 (USB Disconnect) must be set in position 1<->2 in order - to not interfer with SPI2 MISO pin PB14. - - - STM3210B-EVAL Set-up - - Connect SPI1 SCK (PA.05) pin to SPI2 SCK (PB.13) pin - - Connect SPI1 MISO (PA.06) pin to SPI2 MISO (PB.14) pin - - Connect SPI1 MOSI (PA.07) pin to SPI2 MOSI (PB.15) pin - -@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 - -@note - - Low-density Value line devices are STM32F100xx microcontrollers where the - Flash memory density ranges between 16 and 32 Kbytes. - - Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx - microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes. - - Medium-density Value line devices are STM32F100xx microcontrollers where - the Flash memory density ranges between 64 and 128 Kbytes. - - Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx - microcontrollers where the Flash memory density ranges between 64 and 128 Kbytes. - - High-density Value line devices are STM32F100xx microcontrollers where - the Flash memory density ranges between 256 and 512 Kbytes. - - High-density devices are STM32F101xx and STM32F103xx microcontrollers where - the Flash memory density ranges between 256 and 512 Kbytes. - - XL-density devices are STM32F101xx and STM32F103xx microcontrollers where - the Flash memory density ranges between 512 and 1024 Kbytes. - - Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers. - - * <h3><center>© COPYRIGHT 2011 STMicroelectronics</center></h3> - */ |
