(The input portion of this program has not been implelemented.)
Uses the BynaseDriver.
At the MakerFaire we mashed up the above part to make a ThrowieTalkie. This is a simplified variation we make for the GRL exhibit in Austria.
This program generates morse code on keyout (active low) sending a sequence of preprogrammed messages. Keying speed is fixed.
This version of the program has been modified to run at a slow clock rate to reduce power consumption.

DaveTadlock worked out the bit patterns for more Morse letters. Find his work here:
