To enable the carrier frequency feature of the esp32 hardware, specify the

``carrier_freq`` as something like 38000, a typical IR carrier frequency.

So, in the example above, the 80MHz clock is divided by 8. Thus the

resolution is (1/(80Mhz/8)) 100ns. Since the ``start`` level is 0 and toggles

This class provides access to one of the eight RMT channels. *channel* is
|

required and identifies which RMT channel (0-7) will be configured. *pin*,
|

also required, configures which Pin is bound to the RMT channel. *clock_div*
|

is an 8-bit clock divider that divides the source clock (80MHz) to the RMT
|

channel allowing the resolution to be specified. *carrier_freq* is used to
|

be any value that converts to a boolean, with ``True`` representing high

voltage and ``False`` representing low.
|
||||
|
||||
To enable the transmission carrier feature, *tx_carrier* should be a tuple
|
||||
of three positive integers: carrier frequency, duty percent (``0`` to
|
||||
``100``) and the output level to apply the carrier to (a boolean as per
|
||||
*idle_level*).

.. method:: RMT.wait_done(*, timeout=0)
|
||||
|
||||
Returns ``True`` if the channel is currently transmitting a stream of pulses
|
||||
started with a call to `RMT.write_pulses`.
|
||||
|
||||
If *timeout* (defined in ticks of ``source_freq / clock_div``) is specified
|
||||
the method will wait for *timeout* or until transmission is complete,
|
||||
returning ``False`` if the channel continues to transmit. If looping is
|
||||
enabled with `RMT.loop` and a stream has started, then this method will
|
||||
always (wait and) return ``False``.
|
||||
Returns ``True`` if the channel is idle or ``False`` if a sequence of
|
||||
pulses started with `RMT.write_pulses` is being transmitted. If the
|
||||
*timeout* keyword argument is given then block for up to this many
|
||||
milliseconds for transmission to complete.
|

|

.. method:: RMT.loop(enable_loop)
|
||||
|
||||
Configure looping on the channel. *enable_loop* is bool, set to ``True`` to
|
||||
enable looping on the *next* call to `RMT.write_pulses`. If called with
|
||||
``False`` while a looping stream is currently being transmitted then the
|
||||
current set of pulses will be completed before transmission stops.
|
||||
``False`` while a looping sequence is currently being transmitted then the
|
||||
current loop iteration will be completed and then transmission will stop.
|
||||
|
||||
.. method:: RMT.write_pulses(pulses, start)
|
||||
.. method:: RMT.write_pulses(duration, data=True)
|
||||
|
||||
Begin sending *pulses*, a list or tuple defining the stream of pulses. The
|
||||
length of each pulse is defined by a number to be multiplied by the channel
|
||||
resolution ``(1 / (source_freq / clock_div))``. *start* defines whether the
|
||||
stream starts at 0 or 1.
|
||||
Begin transmitting a sequence. There are three ways to specify this:
|
||||
|
||||
If transmission of a stream is currently in progress then this method will
|
||||
block until transmission of that stream has ended before beginning sending
|
||||
*pulses*.
|
||||
**Mode 1:** *duration* is a list or tuple of durations. The optional *data*
|
||||
argument specifies the initial output level. The output level will toggle
|
||||
after each duration.
|
||||
|
||||
If looping is enabled with `RMT.loop`, the stream of pulses will be repeated
|
||||
indefinitely. Further calls to `RMT.write_pulses` will end the previous
|
||||
stream - blocking until the last set of pulses has been transmitted -
|
||||
before starting the next stream.
|
||||
**Mode 2:** *duration* is a positive integer and *data* is a list or tuple
|
||||
of output levels. *duration* specifies a fixed duration for each.
|
||||
|
||||
**Mode 3:** *duration* and *data* are lists or tuples of equal length,
|
||||
specifying individual durations and the output level for each.
|
||||
|
||||
Durations are in integer units of the channel resolution (as described
|
||||
above), between 1 and 32767 units. Output levels are any value that can
|
||||
be converted to a boolean, with ``True`` representing high voltage and
|
||||
``False`` representing low.
|
||||
|
||||
If transmission of an earlier sequence is in progress then this method will
|
||||
block until that transmission is complete before beginning the new sequence.
|
||||
|
||||
If looping has been enabled with `RMT.loop`, the sequence will be
|
||||
repeated indefinitely. Further calls to this method will block until the
|
||||
end of the current loop iteration before immediately beginning to loop the
|
||||
new sequence of pulses. Looping sequences longer than 126 pulses is not
|
||||
supported by the hardware.
