Expand description

Functionality that every OutputChannel must support

Required Methods

Set the logical level that the connected pin is pulled to while the channel is idle

Enable/Disable the output while the channel is idle

Set channel clock divider value

Enable/Disable carrier modulation

Assign a pin that should be driven by this channel

(Note that we only take a reference here, so the ownership remains with the calling entity. The configured pin thus can be re-configured independently.)

Send a pulse sequence in a blocking fashion

Send a raw pulse sequence in a blocking fashion

In this function we expect the sequence elements to be already in the correct u32 format that is understood by the RMT. Please refer to the reference manual or use the variant which accepts PulseCode objects instead.

Stop any ongoing (repetitive) transmission

This function needs to be called to stop sending when previously a sequence was sent with RepeatMode::Forever.
