This project will provide a repository for information on creating homebrew versions of the hardware scoreboard, to operate with the Don Bluth Laserdisc Arcade games Dragon's Lair, Space Ace and Thayer's Quest, using Hypseus Singe. Support for a Space Ace hardware annunciator is also included.

The Hypseus Singe Game API also allows games to utilize this hardware.

Hypseus Singe and an Arduino/Esp32 sketch.

Arduino IDE to load sketch onto Board.

A Windows hypseus binary with USB serial support is provided in Releases.

The project uses serial communication with an Arduino Classic or Esp32 driving MAX7219
8-Digit LED Display Controllers to power 7-segment LED character, or other LED, displays.

The provided sketches demonstrate the serial communication (using serialib) between hypseus
and the Arduino. These should be portable to other programmable microcontrollers able to handle
serial communication.

Required Arduino libraries:
LEDControl
SerialLib

Easy to construct, it can be hand wired on a basic perfboard with LED sizes of your choosing. Be aware of the power consumption of the LEDs as larger displays will require that an exterior power source be implemented. Components can be (DIP/DIL) through hole to enable easy soldering.

Fabrication files can be found in schematics.

• 1    -  Arduino/Esp32 Microcontroller [IC2]
• 16  -  7-Segment display (common cathode) [LED1 to 16]
• 2    -  MAX7219 [IC1 & IC3]
• 2    -  100nf capacitor [C6 - C7]
• 2    -  10uf electrolytic capacitor [C1 - C2]
• 2    -  Resistor [R1 - R2] value:
  _{See table below:}

It can also be created using pre-built and commonly available 8-Digit MAX7219 modules:

See demonstration videos on image links above.

The provided sketches are coded for a 19200 baud rate on the Arduino side.
Baud rates should be adjusted to give the most reliable communication on your hardware.

Updates are communicated using a three byte struct using writeBytes():

typedef struct {
   char unit;
   char digit;
   char value;
} DigitStruct;

The scoreboard DigitStruct.value is 7-bit ASCII suitable for passing via setChar() as a (byte) cast.

The annunciator will recieve 0, 1, 2 or 4 on value, digit is unused.

Scoreboard: unit is 0 | Annunciator: unit is 1

You will need to provide the following arguments to enable serial communication on the required port:

^{(Use 19200 baud for provided sketch)}

In MS Windows:

-usbscoreboard COM <com port decimal> <baud rate>

In Linux, the USB device can appear as USB or ACM. Specify your connection as follows:

-usbscoreboard ACM <com port decimal> <baud rate>
-usbscoreboard USB <com port decimal> <baud rate>

Example:

-usbscoreboard COM 3 19200

Ensure that the hypseus user has read/write permission on the USB device.
Group membership to dialout should normally suffice in linux.

A massive thanks goes out to Rumblebelly5 for the inspiration, patience, schematics, hardware
itinerary and expertise on this project. Without them this project would not be possible.
