SOFTWARE Algorithm

 Values of switches are pointed by allocating their base address

volatile int * switch1_ptr = (int *) 0x0b081040;

volatile int * switch2_ptr = (int *) 0x0b081060;

 For displaying different options on the LCD Display :

sprintf(szText," + ");

vid_print_string_alpha(rcPlus.left+5, rcPlus.top, COLOR_WHITE, COLOR_BLACK, tahomabold_32, display,

szText);

vid_draw_round_corner_box ( rcPlus.left, rcPlus.top, rcPlus.right, rcPlus.bottom, 10, COLOR_WHITE,

DO_NOT_FILL, display);

sprintf(szText," - ");

vid_print_string_alpha(rcMinus.left+10, rcMinus.top, COLOR_WHITE, COLOR_BLACK, tahomabold_32,

display, szText);

vid_draw_round_corner_box ( rcMinus.left, rcMinus.top, rcMinus.right, rcMinus.bottom, 10, COLOR_WHITE,

DO_NOT_FILL, display);

sprintf(szText," & ");

vid_print_string_alpha(rcAnd.left+5, rcAnd.top, COLOR_WHITE, COLOR_BLACK, tahomabold_32, display,

szText);

vid_draw_round_corner_box ( rcAnd.left, rcAnd.top, rcAnd.right, rcAnd.bottom, 10, COLOR_WHITE,

DO_NOT_FILL, display);

sprintf(szText," | ");

vid_print_string_alpha(rcOr.left+10, rcOr.top, COLOR_WHITE, COLOR_BLACK, tahomabold_32, display,

szText);

vid_draw_round_corner_box ( rcOr.left, rcOr.top, rcOr.right, rcOr.bottom, 10, COLOR_WHITE, DO_NOT_FILL,

display);
