*******************************************
* Digispark RC Debug Demo with 1 I/O *
*******************************************
This sketch demonstrates how to display received RC pulse width with a Digispark in the serial console of the arduino IDE.
by 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.
To display properly the outputs in the IDE serial console, you have to:
- in the arduino IDE, select "Tools->Board->Digispark 16.0mhz - NO USB (Tiny core)"
- in the arduino IDE, select the right serial port in "Tools->Serial Port" and select the port where the debug cable is connected to.
- in the serial console, set the right baud rate (38400 in this sketch)
In this sketch, only Tx capabilty of SoftSerial is used.

/*
This sketch demonstrates how to use <SoftRcPulseIn> library to get RC pulses from a receiver and to use <SoftRcPulseOut> library to drive 2 servos.
The first servo will follow the order, and the second one will have a reverted motion.
Please notice this sketch is fully asynchronous: no blocking functions such as delay() or pulseIn() are used.
Tested on arduino UNO, ATtiny84, ATtiny85 and Digispark rev2 (Model A).
