Custom parts and enclosures

Arduino library Clickbutton

This is the most important library you need to get the most functions per button

2018-08-02 - CAD files for the enclosure. Vectric software files AND .dxf files

You are on your own using these files... These are provided 'as is' and you have to think carefully how to mill and in what sequence etc.

/*
   This sketch is to use a Leanardo as a HID for in this case
   an Eding CNC Pendant

   The beauty of using a Leonardo is that you are so flexible!
   I have 20 keys on my Pendant but per key you can use 6 different
   functions. Way too much but I do use on some keys 3 functions.
   Very convienient and easy to use and manage.

/*
  Aduino website notes on using a Leonardo as HID:

  The keyboard functions enable a Leonardo, Micro,
  or Due to send keystrokes to an attached computer.

  Note: Not every possible ASCII character,
  particularly the non-printing ones, can be sent with the Keyboard library.
  The library supports the use of modifier keys.
  Modifier keys change the behavior of another key when
  pressed simultaneously.
  See here for additional information on supported keys and their use.

  Keyboard.begin()
  Keyboard.end()
  Keyboard.press()
  Keyboard.print()
  Keyboard.println()
  Keyboard.release()
  Keyboard.releaseAll()
  Keyboard.write()



  Reference   Language | Libraries | Comparison | Changes

  Keyboard Modifiers

  The Keyboard.write() and Keyboard.press()
  and Keyboard.release() commands don’t work with every possible ASCII character,
  only those that correspond to a key on the keyboard.
    For example, backspace works, but many of the other
    non-printable characters produce unpredictable results.
    For capital letters (and other keys), what’s sent is shift plus the character
    (i.e. the equivalent of pressing both of those keys on the keyboard).

  A modifier key is a special key on a computer keyboard that modifies
  the normal action of another key when the two are pressed in combination.

  For more on ASCII values and the characters or functions they represent,
  see asciitable.com

  For multiple key presses use Keyboard.press()

  The Leonardo's definitions for modifier keys are listed below:

  Key  Hexadecimal value Decimal value
  KEY_LEFT_CTRL     0x80  128
