Running the Example
Once programmed into the board, the example rapidly toggles the Blue LED from the idle loop (blue LED glows) and toggles the Red and Green LEDs as the Philosophers change their state. Additionally, you can depress and hold the SW1 button (left) to PAUSE the application (Table transitions into the "paused" state). Releasing the SW1 button causes transition back to the "serving" state.
