Method sendPulseDistanceWidthData

src/IRSend.hpp:611–648

* Core send function **********************************************************************************************************************/ * Sends PulseDistance data with timing parameters and flag parameters. * The output always ends with a space * @param aOneMarkMicros Timing for sending this protocol. * @param aData uint32 or uint64 holding the bits to be sent. * @param aN

 * @param aFlags            Evaluated flags are PROTOCOL_IS_MSB_FIRST and SUPPRESS_STOP_BIT. Stop bit is otherwise sent for all pulse distance protocols.
