/*
<SoftSerial> library is exactly the same as the <SoftwareSerial> library but used with the <TinyPinChange> library which allows to share
the Pin Change Interrupt Vector.
<SoftwareSerial> monopolizes the Pin Change Interrupt Vector and don't allow sharing.
With <SoftSerial>, it's possible. Don't forget to #include <TinyPinChange> in your sketch!
Additionally, for small devices such as ATtiny85 (Digispark), it's possible to declare the same pin for TX and RX.
Data direction is set by using the new txMode() and rxMode methods.

* Digispark Debug Demo with 1 I/O *
****************************************
This sketch demonstrates how to debug a Digispark using a bi-directional serial port using a single I/O.
This approach allows to use the built-in Serial Console of the arduino IDE.
Please, note this solution requires a native RS232 port (rare today) or a RS232/USB adapter on the development PC.

Software serial multiple serial test
Receives from the hardware serial, sends to software serial.
Receives from software serial, sends to hardware serial.
The circuit:
* RX is digital pin 2 (connect to TX of other device)
* TX is digital pin 3 (connect to RX of other device)

<SoftSerial> adapted from <SoftwareSerial> for <TinyPinChange> library which allows sharing the Pin Change Interrupt Vector.
Single difference with <SoftwareSerial>: add #include <TinyPinChange.h> at the top of your sketch.

/*
Software serial multple serial test
Receives from the two software serial ports,
sends to the hardware serial port.
In order to listen on a software port, you call port.listen().
When using two software serial ports, you have to switch ports
by listen()ing on each one in turn. Pick a logical time to switch
ports, like the end of an expected transmission, or when the
buffer is empty. This example switches ports when there is nothing
more to read from a port
The circuit:
Two devices which communicate serially are needed.
* First serial device's TX attached to digital pin 2, RX to pin 3
* Second serial device's TX attached to digital pin 4, RX to pin 5
