Next make a buffered record of ON OFF button presses along with the time stamps so that a non interrupt function can determine which morse values have been entered. This can then be displayed on the screen. This is based on the PicoAirQ code atmo. In the fututre there may be a microphone amplified and filtered to only hear morse frquencies at audio. this pcb could then listen to morse being played and decode it. An RS-232 output could be used for logging to other computers etc.
