Morse Library (non-blocking sending), Cyclocomp'r

I wrote a Morse library, the key feature of which (to differentiate it from the many others) is that it doesn't block while sending; for example, you can check on a sensor value while a long message is being played on a speaker. On github.

In ultra-brief, you can use it like this:

#define PIN_STATUS  13
LEDMorseSender sender(PIN_STATUS);
void setup() {
    sender.setup();
    sender.startSending();
}
void loop() {
    // do other work, while you...
    sender.continueSending();
}

I wrote it for use in a cyclocomputer (trip meter, histogram of speeds over a ride) project, also on github.
