單片機(jī)源程序如下:
- ;
- ; C51 Snakes ~~~~~~~~~
- ;
- ; Created by Sandeep Sasi
- ; Project Started: 10/09/09, 12:00PM
- ; Project Completed: 30/09/09, 02:10AM
- ; File: C51Snakes.asm
- ; Created by: Sandeep Sasi
- $TITLE ('C51Snakes')
- ; This file defines the Main Block and the entry point of the app.
- ; The app. uses polling technique to sequentially montior the state of the
- ; keys and then bring about the appropriate response. Since there are no blocking
- ; modules and each module will complete executuion within a deterministic time
- ; period, polling tech. proves more efficient over others in implementing this logic!!!
- ORG 0000H ; System reset sets PC to this addr.
- SJMP ResetRecoveryISR ; After a sys. reset, pgm. exe. begins at this inst.
- ORG 0003H
- SJMP ExternalInterrupt0ISR
- ORG 000BH ; Sets PC to this addr. when a Timer 0 overflow signal is raised
- AJMP DisplayMuxISR ; Jump to the corresponding ISR's block
- ORG 0013H
- SJMP ExternalInterrupt1ISR
- ORG 0020H ; All the supporting librarires are place in page one of ROM.
- ; The game library (EggHandle.inc, GameBackEnd.inc and GameFrontEnd.inc) and
- ; C51Snakes.asm will be moved to page two of ROM!!!
- $INCLUDE (ConstAndDataDefs.inc) ; Program Conts.s, redefinition of SFRs and Variable defs.
- $INCLUDE (SystemPower.inc) ; Functions that handle system power down & program recovery after a system reset
- $INCLUDE (DisplayMuxing.inc) ; Function and ISR for Disp. Muxing.
- $INCLUDE (SystemFunctions.inc) ; Fns. to ctrl. disp., buzzer, scan keypad and delay the execution
- $INCLUDE (LowLevelGfx.inc) ; Fuctions that give pixel level access to the disp.
- $INCLUDE (HighLevelGfx.inc) ; Function to clear screen, print text and draw line
- $INCLUDE (WelcomeGfx.inc) ; Functions to display an animation when the console is switched on
- $INCLUDE (DelaySettings.inc) ; Functions to adjust the speed (prop. delay) of the snake
- $INCLUDE (StandByState.inc) ; Fuctions that are called when the app. enters stand by
- $INCLUDE (PauseState.inc) ; Functions that are called when the game is paused
- ORG 0801H ; The core game library functions; Beginning of page two of ROM
- $INCLUDE (EggHandle.inc) ; Functions to handle generation and management of eggs for the snake
- $INCLUDE (GameBackEnd.inc) ; Functions that not directly called from the Main block
- ; The core game logic is handled by these functions
- $INCLUDE (GameFrontEnd.inc) ; Functions that are called from Main block to notify various states of the game
- ; Beginning of the Main Block
- C51Main:
- GameStandBy:
- LCALL _StandBy ; Enter stand by
- GameInit:
- ACALL _NotifyGameBegin ; Initiate the operations before game begins
- LCALL _WaitForAllActionKeyRelease
- MOV PREV_KEY_STATES, #ALL_KEYS_PRESSED ; Force the user to release all keys
- ; to start processing them in the polling loop
- LCALL _ResetSystemIdleTime
- GameRun:
- MOV CURR_KEY_STATES, KEYPAD_ACCESS_PORT ; Sample the state of all keys
- TestForAnyKeyPress:
- MOV A, #ANY_KEY_MASK
- LCALL ADetectedDepressedStateOfKeyMaskInA
- JNZ BeginKeyScan ; If a key press is detected, start scanning the keys sequentially
- LCALL AStepSystemIdleTimeAndNotifyOnExpiry ; If not, advance that system idle time
- JZ EndOfKeyScan ; If system idle period expires,
- ACALL _NotifyGameFreeze ; then freeze the game and
- LCALL _PowerDownSystem ; initiate system power down
- ACALL _NotifyGameRestore ; Recover game from power down state
- LCALL _WaitForAnyKeyPress ; Wait for a user event
- MOV CURR_KEY_STATES, #ALL_KEYS_PRESSED
- SJMP EndOfKeyScan
- BeginKeyScan:
- LCALL _ResetSystemIdleTime
- ScanGamePauseKey:
- MOV A, #PAUSE_KEY_MASK
- LCALL ADetectedDepressingEdgeOfKeyMaskInA ; Check whether the pause key is hit
- JZ ScanDelaySettingsKey ; If not, check the state of Delay Settings key
- ACALL _NotifyGameFreeze ; If yes, initiate a game freeze
- LCALL AGamePause ; Enter paused state
- JZ GameEnd; If the user wishes to quit, end the game and
- ; display the game score
- ACALL _NotifyGameRestore ; Else, initiate game resume
- LCALL _WaitForAnyKeyPress ; After restoring the display to the state when the user
- ; hit the pause key, wait for a user event
- MOV CURR_KEY_STATES, #ALL_KEYS_PRESSED
- SJMP EndOfKeyScan ; Perform no more key processing in this iteration
- ScanDelaySettingsKey:
- MOV A, #DEL_SET_KEY_MASK
- LCALL ADetectedDepressingEdgeOfKeyMaskInA ; Check whether the pause key is hit
- JZ ScanGameActionKeys ; If not, check the state of Game Action Keys
- ACALL _NotifyGameFreeze ; If yes, initiate a game freeze
- LCALL _DelaySettings ; Enter the mode that helps the user to adjust the snake's speed
- ACALL _NotifyGameRestore ; Restore the game once the user has switched back to game mode
- LCALL _WaitForAnyKeyPress ; After restoring the display to the state when the user
- ; hit the pause key, wait for a user event
- MOV CURR_KEY_STATES, #ALL_KEYS_PRESSED
- SJMP EndOfKeyScan ; Perform no more key processing in this iteration
- ScanGameActionKeys:
- ACALL _ScanGameActionKeys
- EndOfKeyScan:
- MOV PREV_KEY_STATES, CURR_KEY_STATES ; Init. PREV_KEY_STATES before next round of processing
- MOV A, #GAME_TIME_STEP_PERIOD
- LCALL _DelayABy100ms
- ACALL ANotifyGameTimeStep ; Initiate a change of game state
- JZ GameOver ; Collision detected; So, game over!
- SJMP GameRun ; Loop around to Game Block
- GameOver:
- ACALL _EndOfGameGfx ; Alert user about end of the game
- GameEnd:
- ACALL _NotifyGameEnd
- ACALL _DisplayGameScore
- SJMP C51Main ; Loop around to Main Block
- END ; End of app.
