筆記2 --- Turn On/Off LVDS

筆記2 --- Turn On/Off LVDS

(only for V10IS)

先將047D bit3 先設為1方能控制

Turn off LVDS：
。 0B36 bit6 = 1
。 0870 bit0 = 1

Turn on LVDS：
。 0B36 bit6 = 0
。 0870 bit0 = 0

PS：
當LVDS關閉後，可用KB或TP動一下即可開啟LVDS

%IF    Icetest  ;mice test
TT_start:
    lda    PwrAP_PwrCtrl                 
    jnb    acc.Cut_LVDS,Exit            ; If PWR AP not select cut LVDS item,jmp     lda    SENSE_FLAG_1
    lda    SENSE_FLAG_1
    anl    a,#03h
    jnz    RstBkLitSaver_1                ; If any key or TP is active, jmp
    jmp    GoBackLitSaver_1            ; Check time is or not up
    ret

    oemclb    BKLightIdleSTS_1,ecLCDBriSeg_1        ; Leave BackLightIdle mode

    mov     r0,#BIOSNORL_LVDS            ; BIOS recory LVDS and Backlight
    call    _PUT_SCI_RECORDER
    mov     a,#080h                    ; A=SCI Task Description Byte
    call    WigglePin
RstBKLFTimer_1:

    CLRBIT    MATRIX_SENSE_1,SENSE_FLAG_1
    RET
GoBackLitSaver_1:
    GETA    0871h
    JNB     ACC.0, Exit
    oemseb    BKLightIdleSTS_1,ecLCDBriSeg_1        ; Don't do again
    SET_BACKLIGHT_OFF                ;;jerry10/13
    mov     r0,#BIOSCUT_LVDS            ; BIOS cut LVDS and Backlight
    call    _PUT_SCI_RECORDER
    mov     a,#080h                    ; A=SCI Task Description Byte
    call    WigglePin
Exit:
    RET
%ENDIF

不過…由於加入上面的code會造成code size爆掉(@@")
所以把某段code刪減成如下：
(因為跟047D原本的功能相衝突，所以就刪它部份功能了:) )

後記：
最後因為每台機種不同的因素，(HW拉線路不同)
有些機種是整個LCD panel都關閉了，
有些機種只是LCD brightness降到某個程度，但訊號依輸出。
可能要改BIOS…大工程= =
(還不知道改哪裡)
後來請Inco用VS寫隻AP通知OS，也能達到相同效果 / \

SendMessage(HWND_BROADCAST, WM_SYSCOMMAND, SC_MONITORPOWER, (LPARAM) 2);
或著
PostMessage(hWnd,WM_SYSCOMMAND,SC_MONITORPOWER,2);
