wince 6.0
pxa270

1*1按键，按照矩阵的方式连接。按下键盘时不产生中断。
部分代码如下

XLLP_BOOL_T XllpKeyPadConfigure(XLLP_KEYPAD_REGS *v_pKeyPadRegs,XLLP_GPIO_T *v_pGPIOReg)
{
XLLP_BOOL_T retval=XLLP_FALSE;
XLLP_UINT32_T GpioDirOutList[]={1,104};
XLLP_UINT32_T GpioDirInList[]={1,101};
XLLP_UINT32_T GpioAltFnPinList[]={2,101,104};
XLLP_UINT32_T GpioAltFnValList[]={2,1,2};
if(v_pGPIOReg != 0)
{
XllpGpioSetDirectionIn(v_pGPIOReg, GpioDirInList);
XllpGpioSetDirectionOut(v_pGPIOReg, GpioDirOutList);
XllpGpioSetOutput0(v_pGPIOReg, GpioDirOutList);
XllpGpioSetAlternateFn(v_pGPIOReg, GpioAltFnPinList, GpioAltFnValList);
}
if(v_pKeyPadRegs != 0)
{
v_pKeyPadRegs->kpControlReg = 1<<26 | 1<<23 |
MAT_SCAN_LINE1|
MATRIX_KP_ENABLE | MATRIX_INTR_ENABLE |
IGNORE_MULTIPLE_KEY_PRESS |
AUTO_SCAN_ON_ACTIVITY;
retval = XLLP_TRUE;
}
return(retval);
}
//物理中断与系统中断绑定
OALIntrStaticTranslate(SYSINTR_KEYPAD, IRQ_KEYPAD);
DWORD KYP_Init(DWORD dwContext)
{
DWORD dwRet = 0;
BOOL result; //
if(!Initialize())//初始化
{
goto KYP_Exit;
}
m_hevInterrupt = CreateEvent(NULL, FALSE, FALSE, NULL); //创建事件
if (!m_hevInterrupt)
{
goto KYP_Exit;
}
result = InterruptInitialize(SYSINTR_KEYPAD, m_hevInterrupt, NULL, 0);//注册事件，即
与中断相绑定
if(!result)
{
goto KYP_Exit;
}
//InterruptDone(SYSINTR_KEYPAD);
if (!IsrThreadStart())//创建新线程
{
goto KYP_Exit;
}
RETAILMSG(1,(TEXT("---------->KeyPad:KYP_Init<----------\r\n\r\n")));
return TRUE;
KYP_Exit:
KYP_Deinit(0);
return dwRet;
}
BOOL IsrThreadStart()
{
BOOL retval = FALSE;
hthrd = CreateThread(NULL,0,(LPTHREAD_START_ROUTINE) KeypdIsrThread,NULL,0,NULL);
if (hthrd != NULL)
{
retval = TRUE;
CloseHandle(hthrd);
}
return retval;
}
void KeypdIsrThread()
{
if ( WaitForSingleObject(hevInterrupt, AutoRepeatTimeout) == WAIT_TIMEOUT )
{
}
else
{
InterruptDone(SYSINTR_KEYPAD);
}
}
