Example description
===================
This example provides a description of how to use a DMA channel to transfer
a word data buffer from FLASH memory to embedded SRAM memory.
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.
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
====================
This example runs on STMicroelectronics STM3210B-EVAL and STM3210E-EVAL evaluation
boards and can be easily tailored to any other hardware.
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 target memory
- Run the example
