Six objects here: The document you re reading & its Chinese version Set of "HWDesign" includes

/*     Very Importany Updata Document
* Yes,as my opinion,There'll be 8 more or at least 4 LEDs on PortNo.0.
* But,as ur view,There are only two LEDs,and U canNOT add any LED more,because
* the rest PINs are defined as fun-control-PIN.
* The worst thing is the first version "myLED" lib and its document is invailed now.
* So re-defined here,but doNOT follow the notes and doNOT use LEDchange!!
