[chuck-users] KBHit vs Hid

[Spencer Salazar]

Hi Atte,
Yes, thats the main difference.  Here are a few extra details that I  
can think of, if you are interested:

KBHit
- provides ASCII value for printable characters
- operates the same across all platforms
- tells you that a key was pressed, but not when it is released
- continually sends the key press if you hold down a key
- on most systems, only one key is reported when multiple keys are  
held down
- only reports key presses when associated terminal is in focus

HidIn keyboard
- provides os-dependent key code for almost all keys
- potentially different codes on different platforms
- tells you when a key was pressed + when it was released
- reports accurately when multiple keys are pressed simultaneously
- reports key presses regardless of window focus
- can handle multiple connected keyboards on Linux/Mac
- is known to not always (not ever?) recognize PS/2 keyboards on Linux

hope this helps!
