<p>Generates and transmits Morse code at a programmable rate.
Storage for 512 characters is provided.
Inputs can be characters or ASCII strings. Most amateur radio CW symbols
are available. Gaussian bandwidth shaping is used, with a rise time of about 5 milliseconds.
The output is a keyed sine wave of programmable frequency and amplitude.</p>

<p class=func><span class=keyword><strong>bool</strong> sendCW</span>(<strong>char</strong> ch);</p>
<p class=desc>This places a single character, ch, into the buffer. If successful,
meaning that the buffer is not full, a <strong>true</strong> is returned.</p>
<p class=func><span class=keyword><strong>bool</strong> sendStringCW</span>
(<strong>char*</strong> pStr);</p>
<p class=desc>This places a string, pointed to by pStr, into the buffer. If successful,
meaning that the buffer is not full, a <strong>true</strong> is returned.</p>
<p class=func><span class=keyword>enableTransmit</span>(<strong>bool</strong> en);</p>
<p class=desc>If en is <strong>true</strong> and the buffer has characters available, CW is sent.
If en is <strong>false</strong> CW is not sent and characters are left in the buffer.
This, of course, does not control PTT. No return value.</p>
<p class=func><span class=keyword><strong>bool</strong> getEnableTransmit</span>();</p>
<p class=desc>Returns the enableTransmit status. If enableTransmit(false) is applied,
the getTransmitEnable() will remain true until the current character is completed.
Additionally, getTransmitEnable() will go false when all characters in the buffer have
been fully sent. This can be useful for control of Transmit/Receive.</p>
<p class=func><span class=keyword>amplitude</span>(<strong>float32_t</strong> a);</p>
<p class=desc>Sets a, the zero-to-peak amplitude of the transmit signal. The default is 1.0.
No return value.</p>
<p class=func><span class=keyword>frequency</span>(<strong>float32_t</strong> f);</p>
<p class=desc>Sets the frequency of the CW waveform. The default is 600 Hz. Any value up to
half of the sample rate can be used.
No return value.</p>
<p class=func><span class=keyword>setLongDashMs</span>(<strong>uint32_t</strong> longDashMs);</p>
<p class=desc>Sets the length, in milliseconds, of the long dash, longDashMs. This is sent by a
semi-colon in the CW buffer. The default is 1000 milliseconds. No return value.</p>
<p class=func><span class=keyword>setSampleRate_Hz</span>
(<strong>const float32_t</strong> &fs_Hz);</p>
<p class=desc>Most standard sample rates are supported. See the Notes below for details. </p>

<p>See the library file radioCWModulator.h for more information</p>
<p>The alphabet includes A to Z (or a to z), 0 to 9, space, quote, dollar,
parentheses, period, comma, hyphen. slash, colon, equal (so-called double dash),
question-mark, under-score, error, KN, AR, SK, AS. There is also a programmable
long dash that is involked by the semicolon. By changing the frequency, amplitude
and length, this can be used as a general purpose pulsed tone generator.
<p>Seeds can be from 5 to 50 words per minute (WPM). From 5 to 30, all integer
speeds are available Above 30, you get the speed lower, or equal, than requested as
30, 35, 40, 45, or 50 WPM.</p>
<p>A 512 character circular buffer holds CW get to be sent. One can add to this buffer
any time. The actual transmission of data is controlled by the enable() function.
If there is any question that the buffer will be over-filled, the getBufferSpace() function
can be used to check.</p>
<p>This runs on T3.x or T4.x.</p>
<P>The built-in Gaussian bandwidth filter only runs with a sample rate around
12 ksps. To support higher rates, the output is "interpolated." The resulting
ranges of supported sample rates are 11.0 ksps to 12.1 ksps, 44.0 ksps to 50.1 ksps,
and 88.0 ksps to 100.1 ksps.</P>
<p>It is planned to add a couple of variables to support fast break-in (QSK I think?).
If someone needs this, let me know at the library Github "messages" and we could
try to finish it up.</p>
