generated documentation for Blink on the telosb platform, you'll see 
documentation for interfaces such as Boot, Leds, and Timer, as well as some from 
the underlying hardware implementations, such as Msp430TimerEvent and 
HplMsp430GeneralIO. </P>
<P>In the navigation panel on the left, components are below interfaces. Click 
on BlinkAppC, and you should a figure like this: </P>

<P>Shaded ovals denote wireable interfaces. Because MainC provides the Boot 
interface and uses the Init (as SoftwareInit) interface, it has two shaded 
ovals. Note the direction of the arrows: because it uses SoftwareInit, the wire 
goes out from RealMainP to SoftwareInit, while because it provides Boot, the 
wire goes from Boot into RealMainP. The details of MainC aren't too important 
here, and we'll be looking at it in greater depth in <A

<P>This lesson has introduced the concepts of the TinyOS component model: 
configurations, modules, interfaces and wiring. It showed how applications are 
built by wiring components together. The next lesson continues with Blink, 
looking more closely at modules, including the TinyOS concurrency model and 
executable code. </P><A name=Related_Documentation></A>

  The TimerMilliC component is a <I>generic component</I> which means that, 
  unlike non-generic components, it can be instantiated more than once. Generic 
  components can take types and constants as arguments, though in this case 
  TimerMilliC takes none. There are also <I>generic interafces</I>, which take 
  type arguments only. The Timer interface provided by TimerMilliC is a generic 
  interface; its type argument defines the timer's required precision (this 
  prevents programmer from wiring, e.g., microsecond timer users to millisecond 
  timer providers). A full explanation of generic components is outside this 
  document's scope, but you can read about them in the nesc generic component 
  documentation.
