Project -
Your project is to design, develop, build and test a digital alarm clock.
You are to use the LCD display to show the current time.
For a high distinction grade your alarm clock MUST:
- Include all the attributes of the pass, credit and distinction grades
- Include additional functionality that in the minds of the academic staff is impressive
- Include a written user manual
- have a user interface that is clean, concise and easy to use.
Defence Question Sheet -
This defence will cover the initial design of their project. It will include interface selection, peripheral comparison and state machine choices.
Q1) Does the design display the time?
a. Display? HH:MM:SS? (or other display)?
b. How is it displayed?
c. Are the state transitions described?
Q2) Does it have 12/24 hour mode?
a. How is it selected?
b. How does it affect the time state machine?
Q3) How do we set the time?
a. How does it affect the time state machine?
Q4) Is there an alarm function?
a. How is it set?
b. How is it triggered?
c. Can we disable it?
d. Can we silence the alarm once triggered?
i. Does the alarm auto re-enable?
e. What happens when the alarm is being changed and it equals the current time?
f. How does it interact with the time state machine?
Q5) Is there a remote alarm display and silence?
a. Does it use the SPI link?
b. How does it work in terms of the alarm state machine?
Q6) Is there Daylight Savings interaction?
a. How is it stored?
b. What are its state transitions?
c. How does it interface with the time state machine?
d. Does it interact with the alarm state machine?
e. What if the alarm is set for a time in between the daylight savings change over times?
f. Are leap years handled?
Q7) Is there a user manual?
a. Is the manual clean and concise?
b. Does the manual describe any additional functionality
Q8) Is there impressive extra functionality?
a. If yes, describe it...
Note - Need only the state machine diagram for the entire project answers to these questions as well with the transition diagram.
