The Running Man Running Man

Background

Arcade Retro Clock started out as a project on an 8x8 matrix. Over the years it has been converted to 16x16 and now 64x32. Each conversion process involved solving many bugs and enhancing the game play especially with respects to the computer's ability to play against itself.

For LEDarcade, I decided to isolate classes, functions, sprites, etc. that are used specifically for displaying messages and animations and to exclude any functions used to control the specific games.

What it can do

LEDArcade has many classes, functions, pre-defined sprites that are used to do the following:

  • draw a sprite
  • move a sprite
  • make a sprite float across the screen
  • raw animated sprites floating across the screen
  • draw text of multiple sizes
  • scroll text left or right at various speeds
  • multiple ways to clear the screen (zooming in / zooming out / fading)
  • scroll the screen around a large map, displaying only a section of the map in a window

There are many more functions available but they are fairly complex. As this project moves forward I will create more examples and document each function.

  • No Screen Output - Troubleshooting

    No Screen Output - Troubleshooting

    I have a RPI ZW2 with a 64x32 screen. It is running MLB, NHL, NBA and a couple other boards without any problems. I performed "git clone https://github.com/datagod/LEDarcade"

    Next I ran: python3 -m pip install --upgrade pip python3 -m pip install --upgrade Pillow

    Now I'm running: "sudo python3 RunningTest.py" = No display on led matrix, but I see the commands being run on my ssh session.

    Also: "sudo python3 RunningTest.py --led-gpio-mapping=adafruit-hat-pwm --led-brightness=40 --led-slowdown-gpio=2 --led-cols=64 --led-rgb-sequence=RBG"

    Both commands have screen outputs as follows:

    --Load Config Data-- Config file not found! Running with default values.

    Suggestion: to slightly improve display update, add isolcpus=3 at the end of /boot/cmdline.txt and reboot (see README.md)

    -- Starry Night Display Text Text1: HIGH SCORES Text2: WATCH THE TOP PLAYERS IN THE WORLD Text3: BREAK RECORDS, MAKE FRIENDS, CELEBRATE EXCELLENCE ElapsedSeconds: 2 ElapsedSeconds: 3 ElapsedSeconds: 5

    Am I missing something simple?

    Thanks!
