*******************************************************
* <TinyPinChange> library Demo *
* with debugging capabilities using *
* <SoftSerial> object as single wire serial interface *
*******************************************************
This sketch demonstrates how to use <TinyPinChange> library.
It counts all the transitions (both edges) on 2 different pins.
/!\CAUTION/!\: as <TinyPinChange> library can be shared (and it is with SoftSerial in this sketch) , the user shall test if the changes are related to the declared pins.
Trick: By connecting Pin#1 to Pin#0 or to Pin#5 through a 1K resistor, you can generate transitions for testing purpose.
Output results are sent to a software serial.
And the great thing is: using a <SoftSerial> object as a bi-directionnal software serial port (half-duplex) on a single pin to communicate with the outside world!
To display the sketch results on a PC (in a Terminal):
1) Build the "Serial One Wire Debug Cable" and plug it to the regular RS232 port as depicted below,
2) Open your favorite Terminal at 38400,n,8,1: HyperTerminal, Teraterm (Windows) or Minicom, GtkTerm (Linux) and CoolTerm (MAC) does the trick.
3) You can also use the Serial Monitor of the arduino IDE: Tools->Serial Port and select your RS232 port (may be an USB virtual port), Rate=38400.
4) To enable the display, type 1, to disable, type 0 in the Terminal/Monitor.
