SoftRcPulseIn library

SoftRcPulseIn is an asynchronous library designed to read RC pulse signals. It is a non-blocking version of arduino pulseIn() function.

Some examples of use cases:

• RC Servo/ESC/Brushless Controller
• Multi-switch (RC Channel to digital outputs converter) (look at RcSeq library)
• Servo sequencer (look at RcSeq library which uses SoftRcPulseOut library)
• RC Robot using wheels with modified Servo to support 360° rotation
• RC pulse stretcher (in conjunction with SoftRcPulseOut library)

Supported Arduinos:

• ATmega328 (UNO)
• ATmega2560 (MEGA)
• ATtiny84 (Standalone)
• ATtiny85 (Standalone or Digispark)
• ATtiny167 (Digispark pro)

Tip and Tricks:

Develop your project on an arduino UNO or MEGA, and then shrink it by loading the sketch in an ATtiny or Digispark (pro).

API/methods:

• attach()
• available()
• width_us()
• timeout()
• LibVersion()
• LibRevision()
• LibTextVersionRevision()

Design considerations:

The SoftRcPulseIn library relies the TinyPinChange library. This one shall be included in the sketch as well.

On the arduino MEGA, as all the pins do not support "pin change interrupt", only the following pins are supported:

• 10 -> 15
• 50 -> 53
• A8 -> A15

On other devices (ATmega328, ATtiny84, ATtiny85 and ATtiny167), all the pins are usable.
