# Dragon's Lair (Arcade) Hardware Scoreboard
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][HS]. Support for a `Space Ace` hardware _annunciator_ is also included.
The Hypseus `Singe Game` API also allows games to utilize this hardware.
## Software
[Hypseus Singe][HS] and an _Arduino/Esp32_ [sketch](sketches/).
[Arduino IDE][AI] to load sketch onto Board.
A Windows _hypseus_ binary with _USB serial_ support is provided in _Releases_.
## Hardware
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][LED]
[SerialLib][SL]
### Hardware details and schematics
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](schematics/).
#### Bill of Materials:
* 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:_
### Using prebuilt LED modules
It can also be created using pre-built and commonly available _8-Digit_ `MAX7219` modules:

**See demonstration videos on image links above.**
## Serial protocol
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`_
## Hypseus command arguments
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
In _Linux_, the USB device can appear as `USB` or `ACM`. Specify your connection as follows:
-usbscoreboard ACM
-usbscoreboard USB
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_.
