macro_rules! for_each_rmt_channel {
    ($($pattern:tt => $code:tt;)*) => { ... };

Available on crate feature _device-selected only.

This macro can be used to generate code for each channel of the RMT peripheral.

For an explanation on the general syntax, as well as usage of individual/repeated matchers, refer to the crate-level documentation.

This macro has three options for its “Individual matcher” case:

• all: ($num:literal)
• tx: ($num:literal, $idx:literal)
• rx: ($num:literal, $idx:literal)

Macro fragments:

• $num: number of the channel, e.g. 0
• $idx: index of the channel among channels of the same capability, e.g. 0

Example data:

• all: (0)
• tx: (1, 1)
• rx: (2, 0)
