Detailed Description
Describes the state of the DMA controller.
Member Data Documentation
◆ channels
| struct no_os_dma_ch* no_os_dma_desc::channels |
References to channels associated with the controller
◆ extra
| void* no_os_dma_desc::extra |
Platform specific data
◆ id
| uint32_t no_os_dma_desc::id |
Unique id of a DMA controller
◆ irq_ctrl
| struct no_os_irq_ctrl_desc* no_os_dma_desc::irq_ctrl |
Interrupt controller configured by the platform specific DMA functions. May be left uninitialized,Start resulting in the interrupt handler not being called once a transfer completes. As such, the user (or platform code) has to provide the cycling mechanism.
◆ mutex
| void* no_os_dma_desc::mutex |
Used to synchronize DMA controller specific operations
◆ num_ch
| uint32_t no_os_dma_desc::num_ch |
The number of channels associated with the controller
◆ platform_ops
| struct no_os_dma_platform_ops* no_os_dma_desc::platform_ops |
Platform specific DMA functions
◆ ref
| uint32_t no_os_dma_desc::ref |
Reference counter
◆ sg_handler
| void(* no_os_dma_desc::sg_handler) (void *) |
Interrupt handler function called when a transfer is completed. It's used to configure the DMA controller for the next transfer in a channel's list.
