****************************************
* 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.
