i want to know digital alarm clock using VHDL


Recommended Posts


the short answer is yes, the retrocade wing could be used to build a digital alarm clock. The display would be very small.


Have you considered using one of these? http://www.gadgetfactory.net/logicstart-megawing/

It has a much larger LED display. Easier to see night and day.


Functionally you will need:

1) Oscillator pulsing at 1Hz. Research the Spartan DCM module.

2) Some counters, e.g. hours, minutes

3) Display control logic e.g. binary to 7 segment converter, display multiplexer.


Most digital electronics texts will show you how. Wakerleys "Digital Design" (4th ed) is an excellent source.
