The file registry must export:
|
|
|
|
|
|
|
|
|
|
STM32_ADVANCED_DMA - TRUE not used by the DMA drivers but other
|
|
|
|
|
drivers use it to enable checks on DMA
|
|
|
|
|
channels. Probably will be removed in the
|
|
|
|
|
future.
|
|
|
|
|
STM32_HAS_DMAx - Support for DMA unit "x" (1..2).
|
|
|
|
|
STM32_DMAx_CHn_HANDLER - Vector name for channel "n" (0..7).
|
|
|
|
|
STM32_DMAn_CHx_NUMBER - Vector number for channel "n" (0..7).
|

|
|
|
|
handling on DMA buffers.
