Instructions
Use Switch 2 to set the hours and Switch 3 to set the minutes. Pressing and holding
either of these switches will make the hours or minutes increment at a fast rate. Toggle
between displaying the time (hours and minutes) and displaying the seconds by
pressing Switch 4.
Discussion
The 32.768 kHz crystal is used to take the guess work out of creating a clock display.
You may recognize this frequency as being 2
clock pulses to seconds in the binary world of a microcontroller. Every time bit 15 in
Timer1 changes, one second has elapsed. A crystal is used because an RC oscillator
will have an unacceptable degree of error after several days.
