SingleWireSerial - Arduino Library that Supports Single-Wire Half-Duplex Serial Communication

I worked on a hardware debugger making use of the debugWIRE protocol, but couldn’t get it to work reliably. So, I worked on my own solution that led to the SingleWireSerial library. It satisfies the following three requirements: single-wire serial communication, extremely accurate and robust up to 125 kbps, and communication speed can be set at runtime.
