I'm using an Arduino Uno with version 0022 of the software. It's installed on a Windows Vista SP2 machine and, up until this morning, everything has worked as expected. I'm new to the Arduino but am pretty experienced with PCs and software. (I write software for a living).
I've been trying to install some libraries for use on my board. This morning I installed the Tone library (from http://code.google.com/p/rogue-code/wiki/ToneLibraryDocumentation
) without any problems. I copied this into the C:\Users\MyUserName\Documents\arduino-0022\arduino-0022\libraries folder on my machine. The Tone library appeared in the Import Library list as expected and loaded correctly when selected.
Later I tried to install the TimeDate library from http://www.arduino.cc/playground/Code/Time
(again by copying to the C:\Users\MyUserName\Documents\arduino-0022\arduino-0022\libraries folder on my machine).
This would not appear in the Import Library list and compiling fails with a selection of error messages!
Now neither the TimeDate nor the Tone libraries appear in the Import Library list. (Odd that the Tone library should disappear when I haven't removed it).
I have also tried copying the Sketchbook folder as described at http://www.arduino.cc/en/Reference/Libraries
If anyone could offer any advice on:
1) Why the Tone library has disapeared?
2) Where I'm going wrong installing the other library?
If I've missed any information you need to know please let me know.
