Thank-you, Stopwatch.
Yes, to both of your questions.
The skip bounce software delay option has to limit the reaction time and accuracy; in the case of very short durations.
Using electronic debounce; the program can read the switch and immediately look for the toggle without software delay.
The software would look in two different places rather than look for a toggle at a single place.
This option requires:
A SPDT switch.
A RS232 Receiver/Transmitter chip.
A Set/Reset latch chip.
A power source for the chips.
One thing that bothers me is the RS232 standard. The standard has levels of plus and minus 15v.
It seems that many RS232 devices, now-a-days, use 0v and +5 volts.
I would appreciate any suggestions about chips and how to implement them.
