Bonus projects should be submitted via email, and critically, with a Piazza post containing a YouTube video demostrating the projet. This way your fellow classmates will see what bonus projects are being done.
[0.25 points] - Make sure that your implementation of Lab3 morse code blinking project is using one of the Timer interrupts for character timing. Display the Morse code message on the RGB led of the Launchpad. Using a different timer interrupt, configure the color of the RGB LED to cycle through the rainbow (at least 16 different colors) while the message is being flashed. The color cycling should be faster than the character timing.
[2-6 points] - MVP (2 points): after implementing the Lab1 morse code blinking project, connect an input GPIO pin of a second MSP430 to the LED driving pin on the first one (you’ll presumably also need to connect the ground lines). Track the signal on this pin to infer dashes, dots, and spaces. Decode these to characters, which can be viewed in memory in the debugger. Extra points: (a) Implement a serial interface to see the translated characters. (b) Figure out how to synchronize the clock over a large range of frequencies. You can assume that the message is limited to 3-4 letters and repeats for a long time. (c) Use a photodiode or other light sensor to get the signal rather than a wire.
[1 point] - Implement a 2 digit stopwatch. With the display PCB oriented horizontally, implement a 2-digit display, and have it count hundredths of seconds. Use the two buttons as a start/stop and reset. When the time is greater than 9.9 seconds, while running, the display should show only seconds. When stopped, it should scroll the full three-digit time.
[1-2 points] - Implement a multi-PCB clock. Use the header pins on the sides of the PCB to chain 2, 4 or 6 of the display PCBs together. Program them such that the rightmost one controls the timing of the rest of the PCBs in the chain. Come up with an interesting way to use one pair of buttons to control the full display, for example, to set the time, or to change the intensity.
[0.5-2 points] - Create some sort of interesting game involving the display and the buttons button. Optional: implement a long press to send the device into LPM4 (like turning off).
[0.25 points] - Demonstrate your soldering skill by removing the 7 330 ohm resistors that limit the LED current and replace them with smaller 100 ohm resistors to make the display brighter. (Note that they are 0402 size!)
Note that all of these are PCB-related bonuses. You can create a second PCB for Lab 4 or submit these designs as part of the midterm or final project board runs. Alternatively, you could have them manufactured yourself. Some of the bonuses are obviously exclusive (i.e., one PCB couldn’t do everything); the rest should be considered additive (if you make one PCB that satisfies multiple bonuses, you get them all.)
[1-2 point] - Create a musical sequencer involving the button, the slide potentiometer, and the buzzer. You should be able to program sequences of sounds with frequency controlled by the potentiometer, with selection and potentially timing controlled by the button. A long press should transition between programming and playback modes.
[0.25 - 0.5 points] - Make nice Youtube video showing your Simon game in action. Make sure that “Rice” and “ELEC327” are in the tile or otherwise searchable. Your demo video should show you playing through to a win, running the “Game Over - Win” animation, and then pushing a button to restart and then playing through but making a mistake to generate the “Game Over - Loss” animation. More points will be given for higher production quality, humor, or other aesthetics.
[0.5 - 1 point each] - Possible improvements or modifications for Simon:
[1-3 points] - Use the accelerometer on the Simon PCB to do something interesting. For example, have the LEDs signal the orientation of the PCB, so that if you hold it sideways, the LEDs always point up. Do something cool where you attach the PCB to a string and swing it in the air to create forces larger than 1g, with the LED denoting the intensity of acceleration.
