DMA1 Channel6 is configured to transfer the contents of a 32-word data buffer stored in Flash memory to the reception buffer declared in RAM. The start of transfer is triggered by software. DMA1 Channel6 memory-to-memory transfer is enabled. Source and destination addresses incrementing is also enabled. The transfer is started by setting the Channel enable bit for DMA1 Channel6. At the end of the transfer a Transfer Complete interrupt is generated since it is enabled. Once interrupt is generated, the remaining data to be transferred is read which must be equal to 0. The Transfer Complete Interrupt pending bit is then cleared. A comparison between the source and destination buffers is done to check that all data have been correctly transferred. @par Directory contents - DMA/FLASH_RAM/stm32f10x_conf.h Library Configuration file - DMA/FLASH_RAM/stm32f10x_it.c Interrupt handlers - DMA/FLASH_RAM/stm32f10x_it.h Interrupt handlers header file - DMA/FLASH_RAM/main.c Main program @par Hardware and Software environment - This example runs on STM32F10x Connectivity line, High-Density, Medium-Density, XL-Density, Medium-Density Value line, Low-Density and Low-Density Value line Devices. - This example has been tested with STMicroelectronics STM32100B-EVAL (Medium-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. @par How to use it ? In order to make the program work, you must do the following : - Create a project and setup all project configuration - Add the required Library files : - stm32f10x_dma.c - stm32f10x_rcc.c - misc.c - system_stm32f10x.c (under Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x) - Edit stm32f10x.h file to select the device you are working on. @b Tip: You can tailor the provided project template to run this example, for more details please refer to "stm32f10x_stdperiph_lib_um.chm" user manual; select "Peripheral Examples" then follow the instructions provided in "How to proceed" section. - Link all compiled 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 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>&copy; COPYRIGHT 2010 STMicroelectronics</center></h3> */
