本人非計算機科班出身，學習單片機是出于個人興趣愛好。為了更好地理解單片機的工作原理，最近學了51單片機匯編語言，學習過程中為了練手，將就手中的一塊開發板寫了這個俄羅斯方塊小游戲，芯片是STC89C52RC，顯示屏是LCD12864（驅動芯片UC1701X，不帶字庫），時鐘芯片是DS1302，游戲過程可以暫停/繼續，可以存檔/讀取存檔（使用芯片自帶的eeprom），時間日期可調。游戲過程中碰撞檢測采用位運算，即將圖塊與背景墻按位與，結果不為0則表示有碰撞。
代碼由9個asm文件組成
LCD12864和DS1302的連線請見代碼內的定義
4x4矩陣鍵盤的說明請見下圖

貼上幾個代碼運行的畫面：

部分代碼如下：

EXTRN BIT (key_pressed_flag,key_renewed_flag,confirm_option,menu_option,is_record_5,is_record_6,If_bottom,auto_down_flag)
EXTRN BIT (if_blink,is_pause,is_escape,Game_over_flag,is_record_1,is_record_2,is_record_3)
EXTRN BIT (is_set_time)

EXTRN DATA (Menu_options,Location_Y,Location_X,Current_block_no,Next_block_no,Current_shape)
EXTRN DATA (msn,auto_down_count,auto_down_count_2,auto_down_speed,Blink_count)

EXTRN IDATA (STACK)

EXTRN CODE (Init_LCD,Clean_screen,Draw_frame,Init_game,Clean_game_area,Load_enter_game_menu,Change_enter_menu_option)
EXTRN CODE (Move_menu_option_by_key,Display_records_menu,BCD_preload_scores,Display_preload_scores)
EXTRN CODE (Load_record,BCD_scores,Display_scores,Set_speed,Display_the_speed,Load_dropping_block)
EXTRN CODE (Create_shape_no,Display_the_next_block,Set_boundary,Copy_background,Cover_background,Display_by_bit)
EXTRN CODE (Recover_background,move_by_key,Judge_and_move_down,Stick_to_background,Judge_and_remove_full_lines,Judge_if_game_over)
EXTRN CODE (Move_down_remained_lines,Count_scores,Display_pause,resume_by_key,Load_exit_game_menu,Change_exit_menu_option)
EXTRN CODE (Display_game_over,Change_record_option,Escape_by_key,Save_record,Scan_keys)
EXTRN CODE (Get_time_from_DS1302,Init_DS1302,Display_time,Display_the_ok_button)
EXTRN CODE (Change_time_option_by_key,Change_time_by_key,Set_time_by_option,Set_time_keys)
EXTRN CODE (Enable_write_to_DS1302,Disable_write_to_DS1302,Write_confirmed_data_to_DS1302,Clr_record_flags)

這個看著不錯，還是可以運用于硬件也就是開發板上的
