tcDspTimer

Introduction

The tcDspTimer class may be used to implement any number of simple timers. methods are provided to set, clear, and check the status of a timer. The sleep function is also provided to put the calling thread to sleep until the timer expires.

Timers are created in a disabled state, after construction the "set" method must be called on a timer to use it.

Example

This is a simple example of tcDspTimer creation and usage:

 {
     tcDspTimer myTimer;

     // some periodic operation
     while (true)
     {
         myTimer.set(MY_PERIOD);

         // perform periodic operation
         ...

         myTimer.sleep();
     }

     // retry something
     myTimer.set(MY_TIMEOUT);
     bool done = false;
     do
     {
         // check if it's done
         ...

     } while (!done && !myTimer.expired());
 
     // see how long "it" takes
     unsiged int remaining;
     myTimer.set(MAX_TIME);

     // do "it"
     ...

     myTimer.expired(&remaining);
     myTimer.cancel();
     printf("There were %1d ticks left (%1d elapsed)\r\n",
            remaining, MAX_TIME-remaining);
 }
