In this design review, you will demonstrate at least two major systems for your project. You will also demonstrate complete device drivers and turn in your mechanical specification.
You need to have at least two main systems complete. An electrical main system usually integrates hardware and software together, although it may be only hardware (analog) or only software (for complex tasks). A mechanical main system may integrate with electronics (sensing, actuation) or may be standalone. A complete system will work without any bugs and without the need for breakpoints, etc. Most projects will require three to five main systems - two must be shown now; the others are required at the end of the quarter.
Some examples of main systems:
 |
Reading a voltage on an A/D and displaying it (accurately) in its final format on a LCD. |
|
Doing a complete send/receive session over the RS232 port |
|
A complete U/I system including all menus and buttons |
|
A complete system for setting the time, date, etc. and displaying it |
|
The analog front end for a particularly difficult sensor |
|
Audio amplifier |
|
A mechanical to electric power converter (generator) producing specified voltage and current at the specified efficiency. |
To prepare for your demonstration, please check the following:
|
Each system demo should be rehearsed to run smoothly, with little operator intervention needed |
|
You may use dummy data if your system doesn't include the input sources |
|
If your system doesn't include outputs, think carefully about the most effective way to show that the outputs are correct |
|
Prepare a list of all of the device driver functions that are used by each system so you won't have to demonstrate them separately (see below) |
|
SET UP YOUR HARDWARE well before the 4:00 design review time |
You should have all of your device drivers written and functioning. This means that all hardware that interfaces with software will be functioning completely. Use the device driver spec as your guide for what you need to write. You will not be required to demonstrate all device drivers (other than those needed for your main functions, above) because of the limited amount of time in design reviews. However, you will be required to verbally confirm that all drivers are complete, and the instructor may ask for evidence of that during the design review.
Your team will have completed the mechanical specification and turned it in by 11:00AM.
Your team should have turned in the following documents by 11:00AM on the day of the review:
Updated schematic, reflecting the FINAL state of your hardware. This should be ready for the PCB designer to use.
Schedule with up-to-date progress marked - email to instructor
All team members must be present at all design reviews. Students with unexcused absences from design reviews will receive a zero grade for the design review.
