Ping))) Rev E and onwards

Starting at Rev E, the Parallax Ping))) module adds a serial interface alongside the existing PWM protocol. The newer module is fully backward compatible.

Here are some SPIN code examples for:

• Original PWM mode (Note: The original PWM code will operate on any revision of Ping or LaserPing module - old or new!)
• Dual PWM mode - operate two Ping))) sensors!
• Serial mode

The serial mode switches the Ping))) module into a serial stream output at 115200 baud.
The measurement data is output in millimeters.
The serial data is encoded as standard ASCII decimal with an ASCII carriage return delimiter.
