Did the work to test and verify....? For whatever reason the port is stuck to ground so the
easy solution for now is to change the code to ignore the keyer.
Analog pin A6 appears to have developed a low resistance to ground about 150 ohms
compared to others at 2-5 megohms.
That done I get normal behavior save for no CW.? that's ok for the work I'm doing.
I plan to rework the code to suit me. If I have to get a few nanos so be it I can just
as easily sub a pro-mini with bunch or wires to the right pins as I have more than a few.
Why that pin failed is a mystery, the header had no wire at all, the 4.7K was on the back
aout of the way.? A7 works fine and could be used for the same purpose if need be.
