Lab 6 Solution

1) Create a synchSM to blink three LEDs connected to PB0, PB1, and PB2 in sequence, 1 second each. Implement that synchSM in C using the method defined in class. In addition to demoing your program, you will need to show that your code adheres entirely to the method with no variations.

2) Create a simple light game that requires pressing a button on PA0 while the middle of three LEDs on PB0, PB1, and PB2 is lit. The LEDs light for 300 ms each in sequence. When the button is pressed, the currently lit LED stays lit. Pressing the button again restarts the game.

3) **(Challenge)** (from an earlier lab) Buttons are connected to PA0 and PA1. Output for PORTB is initially 7. Pressing PA0 increments PORTB once (stopping at 9). Pressing PA1 decrements PORTB once (stopping at 0). If both buttons are depressed (even if not initially simultaneously), PORTB resets to 0. Now that we have timing, only check to see if a button has been pressed every 100 ms. Additionally, if a button is held, then the count should continue to increment (or decrement) at a rate of once per second.
