If anyone is interested in a Morse library, I just finished one based on my original Morse translator, now presenting the Phi_Morse library:
The functions have been improved and the init function takes care of initialization so the number of parameters in most functions has reduced.
This video is taken prior to the library but it shows most features.
Now all you need to do is to include the library and you can do things like
morse_out("HELLO");
to di and dah away or
char a=morse_in(10,0);
and key in your code (display di and dah at 10,0 on LCD), just like that! Everything is explained on my blog page.
