The main function was used to set up the peripherals and threads that were used and described above.

Timer Thread The timer thread is the heart of the entire program. All of the resources that were used by the team were properly credited.

Then each LED has its own data frame where the first 3 bits are 1, followed by a 5 bit value for the intensity level, then a datashdet bit value for blue, green, and red. We settled on temperature because it is very easy to display room temperature in degrees celsius using the minute boxes.

Jason and Eldar decided build 74lls125an wall clock for their final project using the Water Street Clock design. If the sequence is:. The pins were set as digital inputs.

All of our findings throughout this project were reported to Bruce Land, the TAs, as well as fellow students. There are no legal considerations that we are aware of in regards to this project. After waiting for over four and half weeks to receive the WWVB receiver, it finally arrived. Markers dwtasheet important to allow receivers to properly frame the time code. The RTCC periferal is initialized in the main function.


If the sequence is: Unfortunately, we were not able to build a clock that sets the 74ls125n with absolutely no user input. Assistance was provided by the teammates to better each others professional development and support them in following this code of ethics. We used a LM35 analog temperature sensor to read ambient temperature. No existing copyrights or trademarks or patents were found similar to our design.

The LED strips were hot-glued to the back face. For our implementation the clock numbers were displayed on the face of the clock datasgeet from left to write, top to bottom, wrapping around from the end of right row to the beginning of left. However, our implementation was more scalable than creating a table and saving it as a constant.

User input is received via 3 buttons that are connected to the Small Development Board. If a marker symbol is received, we check if the previous symbol was also a marker, which indicates the start of the next frame. The timer thread is the heart of the entire program. This specific value is convenient because it is exactly and makes a 16 bit timer overflow exactly once a second.

Voltage Level Translator 3 Oscillator 9: If power is reduced for four-fifths of a second 0. Before undertaking any technological tasks qualifications were taken into consideration and every time there was doubt about training or experience the TAs and the Instructor were consulted prior to carrying out the task.


Voltage Level Translator 3. But if we are able to pick up a WWVB signal, it will most likely be placed at the top of the device. They were motivated to create a functional piece of technology that adds color, vibrance, and time to any room. We purchased a 25W single output power supply made by Mean Well. Labor Distribution Eldar Housing: Additionally, since the project was inspired by a piece of visual art, we put in extra effort in making it aesthetically pleasing, e.

Honest criticism and errors were accepted and corrected respectively, feedback was sought throughout the project from teammates, fellow classmates, TAs, and Instructors. Unfortunately, we had tremendous difficulty using it and were unable to pick up any trace of a signal in Phillips Hall. Information is encoded using amplitude modulation with the following scheme: The antenna for the WWVB receiver is currently not in the clock because we unable to receive any type of signal from it.

The function begins by converting the day of the year value to month and day values. This is possible because we defined the first trigger to be on a falling edge. High Level Design Rationale: The DotStar strips were driven and powered by 5 V. The rips were fitted in to house the lights and hot-glued in place.
