Detailed Description

Driver configuration set in transfer_api_t::open. All elements except p_extend are required and must be initialized.

Field Documentation

◆ activation_source

elc_event_t transfer_cfg_t::activation_source

Select which event will trigger the transfer.

Note: Select ELC_EVENT_ELC_SOFTWARE_EVENT_0 or ELC_EVENT_ELC_SOFTWARE_EVENT_0 for software activation. When using DTC, these events may only be used once each. DMAC uses internal software start when either of these events are selected.

◆ auto_enable

bool transfer_cfg_t::auto_enable

Select whether the transfer should be enabled after open.

◆ irq_ipl

uint8_t transfer_cfg_t::irq_ipl

Interrupt priority level.

Warning: Unsupported for DTC except when ELC software events are used. DTC transfers trigger the interrupt associated with the activation source.

◆ p_callback

void(* transfer_cfg_t::p_callback) (transfer_callback_args_t *p_args)

Callback for transfer end interrupt. Set to NULL for no CPU interrupt.

Warning: Unsupported for DTC except when ELC software events are used. DTC transfers trigger the interrupt associated with the activation source.

◆ p_context

void const* transfer_cfg_t::p_context

Placeholder for user data. Passed to the user p_callback in transfer_callback_args_t.

◆ p_info

transfer_info_t* transfer_cfg_t::p_info

Pointer to transfer configuration options. If using chain transfer (DTC only), this can be a pointer to an array of chained transfers that will be completed in order.
