Demonstration of an alarm clock as well as temperature display (DS1820). Time is interrupt driven sourced from the PIC external osc. This is more for beginners, like me, starting to learn the C programming language and MikroC Pro using the EasyPicv7.

Setup:
EasyPicv7 development board using PIC 18F45K22
Port E, BITS 0-2 and Port D bit 0 are all using pull down resistors. Set the Port dip switches accordingly.
DS1820 jumper is set for RA4 (PortA.B4).
Piezo buzzer jumper is set for RC2 (PortC.B2)
All Port LEDS are set to off using dipswitch SW4.
Operation:
RE2=Hours, RE1=Minutes, RE0=Seconds, RD0=Alarm on/off
Pressing or holding hours/minutes/seconds buttons increments the time.
Pressing the alarm on/off button for less than a half a second toggles the alarm on and off. Pressing the alarm button for more than a half a second and it enters the "set alarm" mode. In the "set alarm" mode, the hours and minutes buttons are used to set the alarm time. The seconds button has no effect.
When the alarm activates, the LCD displays "Alarm" mode and an alert tone is heard on the piezo. It remains in this mode until the user presses the alarm button. After that, the alert tone is turned off and the LCD displays regular time and temperature.
