In recent years we have responded to hundreds of supports requests on the Arduino Forum, GitHub and elsewhere for many recurring issues with IRremote – the library for Infrared remote control. As many of the issues are similar we decided it was time to develop a ‘IRremoteInfo a Helper utility for troubleshooting IRremote’ that will help users resolve their own issues or failing that, provide solid support information to those who are providing free support services. Today we release the first version of IRremoteInfo, which prints the settings for most of the relevant parameters within the IRremote library, in the hope that users seeking support can post or upload this information when seeking assistance on-line.

IRremoteInfo a Helper utility for troubleshooting IRremote

Example Output
Below we show some sample output from the IRremoteInfo sketch, including:

• Header Information
• A printout of all the important configurable settings within the library
• A list of the different IR protocols available
• Indicators showing whether each protocol is enabled for sending during compile.
• Indicators showing whether each protocol is enabled for decoding during compile.
• A footer which includes some useful information for users.

The Platform which generated this output is an Arduino Nano. (Scroll the panel to the right to see all the sample output)

             - A helper sketch to assist in troubleshooting issues with the library by reviewing the settings within the IRremote library
             - Prints out the important settings within the library, which can be configured to suit the many supported platforms
             - When seeking on-line support, please post or upload the output of this sketch, where appropriate

Notes: 
     - Most of the seetings above can be configured in the following files included as part of the library
     - IRremteInt.h
     - IRremote.h
     - You can save SRAM by disabling the Decode or Send features for any protocol (Near the top of IRremoteInt.h)
     - Some Timer conflicts, with other libraries, can be easily resolved by configuring a differnt Timer for your platform
