Fields

clock_source: ClockSource

Selects the source clock for the RMT channel.

Note that, the selected clock is also used by other channels, which means the user should ensure this configuration is the same when allocating other channels, regardless of TX or RX. For the effect on the power consumption of different clock sources, please refer to the Power Management section.

resolution: Hertz

Sets the resolution of the internal tick counter. The timing parameter of the RMT signal is calculated based on this tick.

memory_access: MemoryAccess

Controls how the channel accesses memory.

interrupt_priority: i32

Set the priority of the interrupt. If set to 0, then the driver will use a interrupt with low or medium priority (priority level may be one of 1, 2 or 3), otherwise use the priority indicated by RxChannelConfig::interrupt_priority.

Please pay attention that once the interrupt priority is set, it cannot be changed until the channel is dropped.

invert_in: bool

Is used to decide whether to invert the incoming RMT signal.

io_loop_back: bool

The signal output from the GPIO will be fed to the input path as well.

allow_pd: bool

Configures if the driver allows the system to power down the peripheral in light sleep mode. Before entering sleep, the system will backup the RMT register context, which will be restored later when the system exit the sleep mode. Powering down the peripheral can save more power, but at the cost of more memory consumed to save the register context. It’s a tradeoff between power consumption and memory consumption. This configuration option relies on specific hardware feature, if you enable it on an unsupported chip, you will see error message like not able to power down in light sleep.
