Abstract What is "Hackers of Catron"? o Electronic Settlers of Catan® board. Settlers of Catan is a resource gathering and trading board game in which players compete to build the largest economy. What we will improve upon? o The game is really fun, but it takes too long to set up. We will shorten the setup process. o Make resource gathering and spending automatic. o This project intends to simplify the execution of Catan without adding more complexity.

Software Design Considerations Modules Continued o GPIO i. LEDs ii. Hall Effect Sensors o DSP i. Random Numbers o Delay Module

Code Design Power On Micro Initialization Initial Piece Placement Game Loop Initial Board Generation Play New Game? Ready for Power Off Wait for Pi to Boot Wait for Pi to Shut Down No Yes

Initial Board Generation For each hexagon o Assign a Resource from available Resource Pool o Remove Resource from Resource Pool Select random edge hexagon o Assign scarcity from list for each resource hexagon in sequence o Skip desert Go to wait for Pi To Boot

Initial Piece Placement Wait for players to join Randomly assign player order For each player 1-4 o Wait for settlement placement and confirm o Wait for road placement and confirm For each player 4-1 o Wait for settlement placement and confirm o Wait for road placement and confirm o Assign Resources Start Game Loop

Main Game Loop While turn isn't over o If dice roll pressed i. Check if 7 1. If yes, make players with more than 7 resources discard half and move thief 2. If no, assign resources to players as appropriate ii. Set Dice Rolled Flag o If dev card played i. Check if knight 1. If yes, move thief 2. If no, place 2 roads

Main Game Loop o Check if piece purchased i. If road, place road ii. If city, place city iii. If settlement, place settlement o Update Board State o Check if Ending Turn i. If yes, clear dice rolled, move to next player ii. If no, continue looping
