Re: CW Mistakes

Does the new Teensy daughter board for the Raduino still use
the resistive voltage divider to detect whether the CW paddle
closure is DIT or DAH?? If that is true, then it might seem that
the problem may be more related to timing than to voltage
thresholds.?

If that is true, then moving the routine that reads the ADC
might be something to look into.? Just repositioning the ADC
read call in original Arduino code might be all that is needed
for those who are stuck with version 3, 4, 5, or 6 Arduino and
the original Raduino.?

Since the original goal of BITX designs was to make a rig
that those with limited funds could use to get on the air, it
would be great if this DIT versus DIT..DAH problem could
be fixed with just a simple change in software.

*** I have it!? Running right now.? The Teensy is orders of magnitude
more powerful than the Nano:? 600MHz clock, a floating point unit( could
do DSP stuff! ) , 8 megabytes of flash, 1 megabyte of RAM, buckets &
barrels of I/O, and built in Ethernet!

? ?I did have to get a new display.? With the original one, the clone
Raduino made unacceptable tuning ticks.? Replacement with a "Hiletgo"
display from
Amazon cured that problem.? So now I have a spare display... More about
that later.

? ?Only thing is... the Teensy is a $30 processor - as opposed to the
nano which costs IIRC $3.
