用軟體模擬驗證你的程式碼吧！

delay 迴圈&decfsz的應用:
WAKE_DELAY: MOVLW #D'255' MOVWF DELAY0 WAKE_DELAY_0: MOVLW #D'255' MOVWF DELAY1 WAKE_DELAY_1: CLRWDT NOP DECFSZ DELAY1,F GOTO WAKE_DELAY_1 DECFSZ DELAY0,F GOTO WAKE_DELAY_0 RETURN 跑馬燈: bsf GP0 call wake_delay bsf gp1 call wake_delay bsf GP2 call wake_delay bsf gp3 call wake_delay goto 跑馬燈 燈的顯示可自由變換 i/o設定在自己用

跟各位大大請教:
小弟是新手,上過一次w100的課,但還是沒有辦法把10f200用上手,我可以燒錄,可以外接按鈕輸入讀到信號,但卻寫不出會動作的delay迴圈, 連做跑馬燈都不行,希望哪位大大可以秀一下10f200的跑馬燈該怎麼寫, 還有為什麼程式會自己一直重複run, 好像decfsz把值都扣光了,卻還在跑??
