Ad hoc tools for playing the Bad Apple!! song's famous animation on the TM4C123GXL LaunchPad with the Nokia 5110 display.

1. Download the original animation video from https://www.youtube.com/watch?v=FtutLA63Cp8
2. Install Python, then the requirements for the Python scripts using pip install -r requirements.txt (preferably in a virtual environment).
3. Use the extract-frames.py script to extract frames from the video using a command like:
   python extract-frames.py --input bad-apple.mp4 --out frames-dir --frame-per-second 25
4. Use the frames-to-bitmaps.py script to convert the frames to a format the Nokia 5110 display can understand, using a command like:
   python frames-to-bitmaps.py --input frames-dir --out bitmaps.bin
5. Copy the resulting file to the bad-apple-ccs/Debug directory. The code assumes it will be named bitmaps.bin though you can change that in bad-apple-ccs/main.c.
6. Hook up your Tiva C board and wire the Nokia 5110 LCD connections as described in the bad-apple-ccs/Nokia5110.h file. Additionally, wire up the backlight pin to the A4 pin on your board, or change it in the bad-apple-ccs/main.c file to your liking.
7. If you don't have Code Composer Studio already installed, install it from here along with the TivaWare library from here.
8. In Code Composer Studio, set up a path variable named TIVAWARE_ROOT pointing to the location of the TivaWare library on your system.
9. Open the bad-apple-ccs folder in Code Composer Studio and run the project in debug mode. Running it in debug mode is vital, as the code uses the C standard library's IO functions to send data to the card through USB. I originally intended to use a MicroSD card adapter to store the data, but couldn't get my adapter to work with the microcontroller.

I extracted 25 frames per second from the video. The resulting video playback on the board was slow (taking about 12 minutes to finish), so I speeded it up by a factor of around 3.5 using ffmpeg:
ffmpeg -i in.mp4 -vf "setpts=(PTS-STARTPTS)/3.5" -crf 18 out.mp4
