DMA Channel6 is configured to transfer the contents of a 32-word data buffer stored in Flash memory to the reception buffer declared in RAM. Trigger is done by software. DMA Channel6 memory-to-memory transfer is enabled. Source and destination address incrementing is also enabled. The transfer is started by setting the Channel enable bit for DMA Channel6. At the end of the transfer a Transfer Complete interrupt is generated if enabled. In the routine, the remaining data to be transferred is read, it must be equal to 0. The Transfer Complete Interrupt pending bit is then cleared. A comparison between the source buffer and the destination buffer is done to check that all data have been correctly transferred. Directory contents ================== stm32f10x_conf.h Library Configuration file stm32f10x_it.c Interrupt handlers stm32f10x_it.h Interrupt handlers header file main.c Main program Hardware environment ==================== No hardware connection needed. 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_dma.c + stm32f10x_rcc.c + stm32f10x_nvic.c + stm32f10x_flash.c - Link all compiled files and load your image into either RAM or FLASH - Run the example ******************* (C) COPYRIGHT 2007 STMicroelectronics *****END OF FILE******
