#747 Using TextFinder

Using the TextFinder library to extract fields from a string with an Arduino.

Notes

The TextFinder library was originally posted by Michael Margolis on the old http://playground.arduino.cc/Code/TextFinder, and discussed in the Arduino Cookbook.

A copy of the code is now hosted and maintained on GitHub.

About TextFinder

TextFinder is a library for extracting information from a stream of data. It was created to be used with the Arduino Ethernet library to find particular fields and get strings or numeric values. I can also be used with Serial data.

For more examples of its use, see:

• TextFinder Library examples
• LEAP#018 FretBoard - for it’s use parsing data from a web page

Serial Example

The UsingTextFinder.ino sketch demonstrates the basic usage of TextFinder with serial data:

• reading an integer
• reading comma-separated list of integers
• reading a floating point number
• reading a string
