I am facing a weird problem:
For tests during development of my software I built a simple circuit
on a Breadboard to test DIO I/O signals.
If I sent a output signal, everything is fine, my test LED turns on.
But I press an input switch, the signal has a variable delay between 0
and about half a sec.
The switches are not debounced, I wanted to do that in the software. I
wrote a loop that sends the input signal inverted to the output, so I
was expecting some jitter at the LEDs.
But instead of this the LEDs turn on, but with the described delay.
That happens in TS-Linux as well as in Debian, so I suppose it's not
because of other processes...
Then I made a simple bridge between GND and an input line to check if
the board's capacity is the reason - same result.
I'm a bit out of ideas now, any hint would be great,
Albrecht
