goflip is a Go/golang package for controlling a pinball machine. It's purpose is to run the game rules as well as communicate to the peripheral arduino devices.

go get github.com/jfleitz/goflip

Check out the Mike Bossy pinball project on how to use: http://www.github.com/jfleitz/Bossy

goflip utilizes the serial ports to communicate with the arduino peripherals. The following are required to be connected when using goflip:

• 8x8 Switch Matrix (Arduino nano)
• Lamp Driver Unit (LDU - Arduino nano)
• Solenoid Driver Unit (SDU - Arduino nano)

• GameStart = called when a credit is added to the machine (someone * presses the credit button)
• AddPlayer = adds to the number of players in the game
• PlayerUp = called every time that a new player is up
• PlayerEnd = called every time a player loses the ball in play
• PlayerFinish = called at the very end of the game for that player
• GameOver = called at the very end of the game

• BallDrained = called when a ball is now found in the outhole
• BallInPlay = called when a ball is launched

A player walks up and puts a coin in the machine (or freeplay and they don't)

• Credit button is pressed
  • GameStart event is callled
  • AddPlayer event is called (since credit button was pressed)
  • PlayerUp event is called (since we have player 1 in the game now)
• Another credit button is pressed and on Ball 1 still
  • AddPlayer event is called to add another player

Player X starts playing and launches the ball

• BallInPlay event is called

Player X loses the ball (and no ball save or after ball save)

• BallDrained is called
  • PlayerEnd is callled
    • If last ball was played for that player, then PlayerFinish is called
    • If more players or not the last ball, PlayerUp is called with next player
    • If no more balls left, then GameOver is called

• Display driver support
• LDU - short message support (currenly 4 byte messages)
• Remote monitoring (web interface)
