/* 
DEMO92.c: Shows how to use the StopWatch function on channel 0 to switch the LED ON or OFF.

Compiler: BC++ 3.1, 
          Turbo C++ 1.01(3.01) (free from http://cc.codegear.com/free/cpp)
          MSC 6.0,
          MSVC 1.52.

Compile mode: Large

Project: DEMO92.c 
         ..\..\Lib\(8000e.Lib, 7188el.Lib or 7186el.Lib)

Hardware: i-7188/uPAC-7186/i-8000

Note: Function used:
      TimerOpen --> begin to use uPAC-7186 timer
      TimerClose --> stop to use timer
      StopWatchStart  --> start to count time interval
      StopWatchReadValue -->to decide if time is up.
      Use StopWatch to count 500ms(0.5s) to turn LED ON or OFF.
