Member Data Documentation
◆ cb_desc
| struct no_os_callback_desc no_os_dma_ch::cb_desc |
irq callback
◆ extra
| void* no_os_dma_ch::extra |
◆ free
| bool no_os_dma_ch::free |
Whether or not there is a transfer in progress on this channel
◆ id
| uint32_t no_os_dma_ch::id |
Channel number
◆ irq_ctx
| struct no_os_dma_default_handler_data no_os_dma_ch::irq_ctx |
IRQ parameter for the default inter transfer handler
◆ irq_num
| uint32_t no_os_dma_ch::irq_num |
Channel specific interrupt line number
◆ mutex
| void* no_os_dma_ch::mutex |
Used to synchronize channel specific operations
◆ sg_list
| struct no_os_list_desc* no_os_dma_ch::sg_list |
List of transfers for this channel
◆ sync_lock
| bool no_os_dma_ch::sync_lock |
Mark the channel as locked, in order to prevent it from being acquired even if it's free. Used as a synchronization mechanism between channels.
