C++ (Cpp) DMA_FLAG_OFFSET Examples

Example #1

File: dma_common_l1f013.c Project: insane-adding-machines/unicore-mx

void dma_clear_interrupt_flags(uint32_t dma, uint8_t channel,
			       uint32_t interrupts)
{
/* Get offset to interrupt flag location in channel field */
	uint32_t flags = (interrupts << DMA_FLAG_OFFSET(channel));
	DMA_IFCR(dma) = flags;
}

Example #2

File: dma_common_l1f013.c Project: insane-adding-machines/unicore-mx

bool dma_get_interrupt_flag(uint32_t dma, uint8_t channel, uint32_t interrupt)
{
/* get offset to interrupt flag location in channel field. */
	uint32_t flag = (interrupt << DMA_FLAG_OFFSET(channel));
	return ((DMA_ISR(dma) & flag) > 0);
}

Example #3

File: dma_common_f13.c Project: dipspb/libopencm3

void dma_clear_interrupt_flags(u32 dma, u8 channel, u32 interrupts)
{
/* Get offset to interrupt flag location in channel field */
	u32 flags = (interrupts << DMA_FLAG_OFFSET(channel));
	DMA_IFCR(dma) = flags;
}
