Description

ICMP Ping library for the Arduino.

Requirements

This library works with the Arduino Ethernet shield. I have tested it with the Arduino Duemilanove, but it should work with any model that is compatible with the Ethernet shield.

Setup

  • Download the zip file or clone the repo
  • Copy the icmp_ping directory into the libraries directory of your Arduino folder.

Usage

The basic steps for using this library are:

  • Import the heder ICMPPing.h
  • Import Ethernet.h
  • Start Ethernet
  • Create an instance of ICMPPing
  • Use one of the two overloaded functional-call operators to send and receive an ICMPEcho.

For documentation of all classes and methods, see ICMPPing.h

Example
