This code provides functions that may prove useful in implementing the Lab 5 game

The player is represented by an unsigned char containing a position on the board. Relies on an LCD library - included as LCD/LCD.h.

• unsigned char initPlayer();

  • returns the address of the first position in the game
  • this can be called to place the player at the starting position

• void printPlayer(unsigned char player);

  • prints the player symbol to the passed in location

• void clearPlayer(unsigned char player);

  • clears the passed in location by printing a space

• unsigned char movePlayer(unsigned char player, unsigned char direction);

  • returns an updated position based on an input position and direction of movement
  • constants for UP, DOWN, LEFT, and RIGHT are included in the header

• char didPlayerWin(unsigned char player);

  • returns 1 if the player is at the winning position, 0 otherwise

• void BOOM(); -prints BOOM! on the top and bottom lines of the LCD and waits a set time, or until a button is pushed

• void displayYouWon(); -prints You Won! to the LCD screen, you on top and won on bottom

• unsigned char gameOver(); -displays Game on the top LCD line and Over! on the bottom LCD line

• void setMines(unsigned char firstMine, unsigned char secondMine); -draws an X on the designated locations of the mines

These are the other funcitons, but are declared in main

• void generateAndSetMines(); -randomly creates locations for two mines -if the mines are stacked or diagonal, it will keep generating random locations
• void init_timer(); -stop timer -clear TAR -configure for SMCLK -divide timer clock by 8 -clear interrupt flag -set count mode to continuous -enable interrupt
• void init_buttons(); -set buttons to input -enable the interrupts -configure interrupt to sense falling edges -enable internal pull-up/pull-down network -configure as pull-up -clear flags -#pragma vector=TIMER0_A1_VECTOR; -__interrupt void TIMER0_A1_ISR(void);` -clears interrupt flag -Flag for continuous counting is TAIFG -every 0xffff clock cycles, the timer overflows and the interrupt occurs -the timer ticks one count every clock cycle -sets flag to 1, saying the timer overflowed

-#pragma vector=PORT1_VECTOR; -__interrupt void Port_1_ISR(void) -configures interrupts for buttons -P1IES this is what triggers the interrupt, if it is 1, the interrupt will trigger on --a falling edge. If it is 0, the interrupt will trigger on a rising edge. P1 Edge Select.
