STC90C52RC製作打磚塊遊戲

STC90C52RC單片機可以用來製作各種有趣的遊戲，包括打磚塊遊戲。下面是一個簡單的打磚塊遊戲的程式碼示例，使用STC90C52RC單片機和一個16x2的LCD顯示屏，同時還需要一些按鈕、蜂鳴器和其他電子元件。

以下是示例程式碼：


#include <STC89.H>

#define LCD_RS P2_5
#define LCD_RW P2_6
#define LCD_E  P2_7

#define LCD_DATA P0

#define BTN_LEFT P3_1
#define BTN_RIGHT P3_2

#define BEEPER P3_3

unsigned char const BARRIER[] = { 0x0F, 0x1F, 0x3E, 0x7C, 0x7C, 0x3E, 0x1F, 0x0F }; //磚塊位圖
unsigned char const BALL[]    = { 0x04, 0x0E, 0x1F, 0x0E, 0x04 };                       //球的位圖

unsigned char buf;    //顯示屏緩存區
unsigned char score = 0;  //分數
unsigned char bar_x = 7;  //磚塊橫向位置
unsigned char ball_x = 7; //球的橫向位置
unsigned char ball_y = 1; //球的縱向位置
signed char ball_dx = 1;  //球的橫向速度
signed char ball_dy = 1;  //球的縱向速度

void delay(unsigned int t)

        lcd_write_cmd(0x80 + x);
    else
        lcd_write_cmd(0xC0 + x);

    for (i = 0; str; i++)
        lcd_write_data(str);
}

void draw_barrier()
{
    unsigned char i, j;

for (i = 0; i < 8; i++) {
    for (j = 0; j < 8; j++) {
        if (BARRIER & (1 << j))
            buf |= (1 << j);
        else
            buf &= ~(1 << j);
    }
}
}

void draw_ball()
{

    buf[(ball_y + i) * 2 + ball_x / 8] |= BALL << (ball_x % 8);

lcd_puts(6, 0, (unsigned char *)score + '0');
}

            lcd_puts(5, 1, "GAME OVER");
            while (1);
        }
    }

    draw_ball();
    draw_screen();
    delay(10);
}
}



這個程式碼使用了16x2的LCD顯示屏來顯示分數和遊戲畫面，同時還使用了幾個按鈕和一個蜂鳴器。在遊戲開始時，磚塊和球的初始位置會被設置，並且畫面會被繪製出來。
