4.2键盘驱动

4.2键盘驱动 [复制链接]

有做过矩阵键盘的指导下：
在oalintr.h 添加了中断的定义，CFW.C和ARMINTI.C添加了相应的实现。
s3c2440kbd.cpp文件修改如下：
BOOL Ps2Keybd::IsrThreadProc()
{
....
extern UINT v_uiPddId;
        extern PFN_KEYBD_EVENT v_pfnKeybdEvent;

        KEYBD_IST keybdIst;
        keybdIst.hevInterrupt = m_hevInterrupt;
        keybdIst.dwSysIntr_Keybd = dwSysIntr_Keybd;
        keybdIst.uiPddId = v_uiPddId;
        keybdIst.pfnGetKeybdEvent = KeybdPdd_GetEventEx2;
        keybdIst.pfnKeybdEvent = v_pfnKeybdEvent;

        RETAILMSG(DEBUGMODE, (TEXT("IsrThreadProc Call KeybdIstLoop()\r\n")));               
        KeybdIstLoop(&keybdIst);
....
}

static UINT KeybdPdd_GetEventEx2(UINT uiPddId, UINT32 rguiScanCode[16], BOOL rgfKeyUp[16])
{
....
ui8ScanCode = (UINT8)GetKeySCode(); //add 这个是我的键盘扫描函数
    RETAILMSG(DEBUGMODE, (TEXT("[KeybdPdd_GetEventEx2] ui8ScanCode : %x\r\n"),ui8ScanCode));
    DEBUGMSG(ZONE_SCANCODES,
        (_T("%s: scan code 0x%08x, code in progress 0x%08x, previous 0x%08x\r\n"),
        pszFname, ui8ScanCode, scInProgress, scPrevious));
   
        
     scInProgress = ui8ScanCode;
....
}

BOOL Ps2Keybd::KeybdPowerOn()
这个函数进行了中断和IO的初始话，

其他的几个文件改动不打。

编译下载后出现了：
-----Call Matrix_Entry-----
Initialize Matrix ID
Ps2Keybd::Initialize
IsrThreadStart:
++KeybdDriverInitializeAddresses
Touch Init
call Ps2KeybdIsrThread:
call IsrThreadProc:

Call InterruptInitialize()

AKY=00000009 PC=034a5d40 RA=034a5d30 BVA=080000d4 FSR=00000007

按键没有任何反应，大家看下那里错了，谢谢了

怎么没人回答啊

产生异常自己退出DLL了

4.2和5.0 没有什么不同，只有中断申请不同而已。
我就是让4.2的键盘驱动放在5.0下运行的。

中断初始化的问题吧，InterruptInitialize()初始化硬件管脚、中断等。
之后就进入IsrThreadStart->KeybdIstLoop等待键盘中断。

看你的信息，是KeybdIstLoop函数中，直接发生数据异常了Data Abort

1. IsrThreadProc Call KeybdIstLoop()
   
2. Data Abort: Thread=8fbf6c9c Proc=8d426a08 'gwes.exe'
   
3. AKY=00000009 PC=034a5d40 RA=034a5d30 BVA=080000d4 FSR=00000007

谢谢，楼上的，我参考了那文章，那问题解决了！！出现新问题了！！

我定义的中断号

        //        Since we don't need the handle, close it now.
        CloseHandle(hthrd);
        Sleep(1);
        key_index ++;
        }
        return TRUE;
}

只有SYSINTR_EINT13 调用InterruptInitialize（）成功，其他的全失败了，和SYSINTR_EINT13在数组中的位置无关，在CFW.C和arminit.c中它们的相应实现时一样的啊，为什么啊，有其他好的方法实现矩阵键盘的吗？

怎么没人给个消息啊

问题解决了，但是我没明白原理呵呵，采用的是系统的原有的中断
