New to arduino - so description may be a little off & based on current understanding - sorry in advance. Corrections &/or questions appreciated. . Adafruit forum lead me here (http://forums.adafruit.com/viewtopic.php?f=22&t=72316) . Bought Adafruit HELLA = trellis controllers + leonardo + teeOnArdu + MIDI from teensy libraries = MIDI device. Win7 PC . Can talk to the Leonardo. Can run the trellis tests - all led & buttons functional, no obviosu hardware or connectivity issues. . Problem: TeeOnArdu files copied, but not seen by Arduino 1.6.3 - does not appear on Tools>Boards list . File>Preferences & preferences.txt confirm sketchbook is C:\Users\Spark\Documents\Arduino . Created hardware directory (in C:\Users\Spark\Documents\Arduino). Copied TeeOnArdu files into hardware directory . Arduino IDE 1.0.5 sees them, no problem, but does not like the teensy libraries. - not an option to continue with the older IDE. Teensyduino splash screen does say "for Arduino 1.06,1.6.1, 1.6.1-j7, 1.6.2 1.6.3" so I guess I am not so surprised. . The adafruit forum came up with the obvious answer: put things in the right place. Seems that if 1.0.5 finds the "hardware" & adds TeeOnArdu to the Tools?Boards list - then it's probably in the right place. . It has to be something obvious. Cannot see the mistake. . C:\Users\Spark\Documents\Arduino holds
hardware libraries Toys UNTZtrument_Hello_World . C:\Users\Spark\Documents\Arduino\hardware holds
TeeOnArdu . C:\Users\Spark\Documents\Arduino\hardware\TeeOnArdu holds
bootloaders cores Examples boards.txt . Adafruit confirm that they have been unable to reproduce the problem. . Obviously while prospecting for an IDE version that works, I've re-installed, (uninstall+new install) repeatedly. Seems the sketchbook contents are not deleted each time, but, well, they have not changed. . Anyone see the problem? Can someone point me to the method used to detect "hardware", so I can go through & check each thing off? Is there a start-up log file? Any other suggestions?
