The DMA channels +involved in this transfer depend on the used SPIs (for more details please refer +to platform_config.h file). + +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 SPI_MASTER +and SPI_SLAVE 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. + + +@par Directory contents + + - DMA/SPI_RAM/platform_config.h Evaluation board specific configuration file + - DMA/SPI_RAM/stm32f10x_conf.h Library Configuration file + - DMA/SPI_RAM/stm32f10x_it.c Interrupt handlers + - DMA/SPI_RAM/stm32f10x_it.h Interrupt handlers header file + - DMA/SPI_RAM/main.c Main program + - DMA/SPI_RAM/system_stm32f10x.c STM32F10x system source file + +@par Hardware and Software environment + + - This example runs on STM32F10x Connectivity line, High-Density, Medium-Density, + XL-Density, High-Density Value line, 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), STM32100E-EVAL (High-Density Value line), STM3210C-EVAL + (Connectivity 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. + + - STM32100E-EVAL Set-up + - 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) + + - STM32100B-EVAL Set-up + - 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) + + - STM3210C-EVAL Set-up + - Connect SPI3 SCK pin (PC.10) to SPI2 SCK pin (PB.13) + - Connect SPI3 MISO pin (PC.11) to SPI2 MISO pin (PB.14) + - Connect SPI3 MOSI pin (PC.12) to SPI2 MOSI pin (PB.15) + @note In this case SPI3 pins are remapped by software. + + - STM3210E-EVAL Set-up + - 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 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 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) + + +@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> + */ |
