/* 
DEMO96.c: Using a timer interrupt function to controll the 5-Digit 7-segment LED.

Compiler: BC++ 3.1,
          Turbo C++ 1.01 (3.01),
          MSVC 1.52

Compile mode: Large

Project: DEMO96.c
         ..\..\Lib\upac5000.lib

Hardware: uPAC-5000

Description
    TimerOpen(): Starts the timer.
    TimerClose(): Stops the timer.
                  If TimerOpen() is called within your program, it must call TimerClose() before exiting.
    InstallUserTimer(): Install a custom timer function and the function will be called at regular intervals of 1 ms.
    
    Each digit of the LED is numerically identified  from left to right using the numbers 1 to 5.
    5-Digit 7-segment LED show 0 to F.
    
    LED #1 will be updated every 1 sec
    LED #2 will be updated every 0.5 sec
    LED #3 will be updated every 0.4 sec
    LED #4 will be updated every 0.3 sec
    LED #5 will be updated every 0.2 sec
