Function Documentation

◆ dma_base()

static DMA_TypeDef* dma_base ( int  stream)
inlinestatic

For simplifying DMA stream handling, we map the DMA channels transparently to one integer number, such that DMA1 stream0 equals 0, DMA2 stream0 equals 8, DMA2 stream 7 equals 15 and so on.

Parameters
[in]streamlogical DMA stream

Definition at line 105 of file stm32f2/include/periph_cpu.h.

◆ dma_hl()

static int dma_hl ( int  stream)
inlinestatic
Parameters
[in]streamlogical DMA stream
Returns
0 for streams 0-3, 1 for streams 3-7

Definition at line 130 of file stm32f2/include/periph_cpu.h.

◆ dma_ifc()

static uint32_t dma_ifc ( int  stream)
inlinestatic
Parameters
[in]streamlogical DMA stream

Definition at line 140 of file stm32f2/include/periph_cpu.h.

◆ dma_isr_enable()

static void dma_isr_enable ( int  stream)
inlinestatic
Parameters
[in]streamlogical DMA stream

Definition at line 161 of file stm32f2/include/periph_cpu.h.

◆ dma_poweron()

static void dma_poweron ( int  stream)
inlinestatic
Parameters
[in]streamlogical DMA stream

Definition at line 87 of file stm32f2/include/periph_cpu.h.

◆ dma_stream()

static DMA_Stream_TypeDef* dma_stream ( int  stream)
inlinestatic
Parameters
[in]streamlogical DMA stream
Returns
base address for the selected DMA stream
