A (micro/u) Morse Encoder
To build the test binary run
make -C tests/
./tests/test
The default delay for a Morse DIT is 60ms (milliseconds), which is quiet fast for Morse beginners. To increase the timing interval, e.g. to 240ms, run
CFLAGS=-DUMORSE_DELAY_DIT=240 make -C tests/ clean all
./tests/test
