Manchester code (phase encoding) library

It implements Manchester code according to both IEEE 802.3 and G.E. Thomas' conventions.

• A '0' is expressed by a high-to-low transition, a '1' by low-to-high transition in the IEEE 802.3 convention. The reverse is true in the G.E. Thomas' convention.
• The transitions which signify '0' or '1' occur at the midpoint of a period.
• Transitions at the start of a period are overhead and don't signify data.
• Least significant bit is sent first
• There are synchronization pulses (the number can be set) at the begin of transmission
  
  Select a convention to be used by commenting or uncommenting the line below in the Manchester.h header file.
  

#define G_E_THOMAS 1

The IEEE 802.3 convention is used by default.

A Manchester encoded message (using G.E. Thomas' convention), with one sync pulse in the preamble, carrying four bytes:

ACKNOWLEDGEMENT: The code in this library was based on this article published by Robert Guastella.

NOTE: To perform a simple test (without radio modules) connect the txPin on transmitter board to the rxPin on the receiver board and make sure that grounds are also connected one another.
