Design a simple digital clock., Computer Engineering

Assignment Help:

Use a timer interrupt to design a easy digital clock.  This clock will count only minutes and seconds, and start at 00:00 every time your program starts.  The show on the screen should read

 mm:ss

The display should be consider on one line, and should only update once a second. There will also be a ticking sound on the speaker once each second.

How should you make the clock?  The specific method you use is up to you.  Here are a few suggestions to get started:

 

  • You can count interrupts to count seconds. For instance, if you use a 32 ms rate, one second is roughly 31 interrupts.
  • When your clock reaches 59:59, reset the whole thing to 00:00 and start counting again.
