##### How to use this driver #####
|
||||
==============================================================================
|
||||
[..]
|
||||
The DMA Extension HAL driver can be used as follows:
|
||||
(#) Start a multi buffer transfer using the HAL_DMA_MultiBufferStart() function
|
||||
for polling mode or HAL_DMA_MultiBufferStart_IT() for interrupt mode.
|
||||
|
||||
-@- In Memory-to-Memory transfer mode, Multi (Double) Buffer mode is not allowed.
|
||||
-@- When Multi (Double) Buffer mode is enabled the, transfer is circular by default.
|
||||
-@- In Multi (Double) buffer mode, it is possible to update the base address for
|
||||
the AHB memory port on the fly (DMA_SxM0AR or DMA_SxM1AR) when the stream is enabled.
|
||||
