An Electronic Chessboard Using RGB LED Strips and Hall Effect Sensors: part2

摘要

A flow chart of the Teensy 3.1 loop() function is shown in Figure 1. The mainLoop() function contains the majority of the functionality of the chessboard program; a simplified flow chart of it appears in Figure 2. The mainLoop() function processes three possible legal moves for each turn: 1. A piece moves to a legal empty space. 2. A piece is picked up, but is just returned to its original location. 3. A piece captures an opponent's piece.
