irda driver for wince6

[zym0805]

Can Adeneo at91x wince bsp for serial driver support irda mode? Can anybody answer this question?

how can modify serial driver of Adeneo wince bsp to support irda mode?

解决方法：

1.第一步在Serial_SAM926X_HW.cpp中添加

//-----------------------------------------------------------------------------
//! \fn VOID HWSetIrFilter (T_SERIAL_INIT_STRUCTURE *pInitContext, DWORD dwFilter)
//-----------------------------------------------------------------------------
VOID HWEnableIrMode (T_SERIAL_INIT_STRUCTURE *pInitContext)
{
EnterCriticalSection(&pInitContext->csUsartReg);
pInitContext->pUSARTReg->US_MR &= ~AT91C_US_USMODE;
pInitContext->pUSARTReg->US_MR |= AT91C_US_USMODE_IRDA;
pInitContext->pUSARTReg->US_IF = 30;
pInitContext->m_fIREnable = 1;
LeaveCriticalSection(&pInitContext->csUsartReg);
}

//-----------------------------------------------------------------------------
//! \fn VOID HWSetIrFilter (T_SERIAL_INIT_STRUCTURE *pInitContext, DWORD dwFilter)
//-----------------------------------------------------------------------------
VOID HWDisableIrMode (T_SERIAL_INIT_STRUCTURE *pInitContext)
{
EnterCriticalSection(&pInitContext->csUsartReg);
pInitContext->pUSARTReg->US_MR &= ~AT91C_US_USMODE;
pInitContext->pUSARTReg->US_MR |= AT91C_US_USMODE_NORMAL;
pInitContext->m_fIREnable = 0;
LeaveCriticalSection(&pInitContext->csUsartReg);
}

//-----------------------------------------------------------------------------
//! \fn
//-----------------------------------------------------------------------------

VOID HWIrdaPutByte(T_SERIAL_INIT_STRUCTURE *pInitContext, BYTE ch)
{
while(!(pInitContext->pUSARTReg->US_CSR & AT91C_US_TXEMPTY));
pInitContext->pUSARTReg->US_THR = (ch & 0x1FF);
while(!(pInitContext->pUSARTReg->US_CSR & AT91C_US_TXEMPTY));
}


第二步：修改Serial_SAM926X.cpp中COM_IOControl的函数，添加使能红外和禁止红外的函数；

case IOCTL_SERIAL_ENABLE_IR :
//DEBUGMSG (ZONE_IR,(TEXT("IOCTL Enable IR not supported\r\n")));
HWEnableIrMode(pHWIHead);
break;
case IOCTL_SERIAL_DISABLE_IR :
//DEBUGMSG (ZONE_IR,(TEXT("IOCTL Disable IR not supported\r\n")));
HWDisableIrMode(pHWIHead);
break;


第三步：修改COM_Write的函数，增加红外模式功能：

else if(pInitContext->m_fIREnable == 1)//红外模式
{

ULONG byteID=0;

HWDisableReceive(pInitContext);

pInitContext->pUSARTReg->US_CR = AT91C_US_TXEN;

while(byteID<NumberOfBytes)
{
HWIrdaPutByte(pInitContext, pSourceBytes[byteID]);
byteID++;
}

pInitContext->pUSARTReg->US_CR = AT91C_US_TXDIS;

HWEnableReceive(pInitContext);

dwNbByteSent = byteID;
//printf("comm_send\r\n ");
RETAILMSG (1,(TEXT("-COM_WRITE: returning %d\r\n"),byteID));

}

第四步：应用时除了Create后，调用KernernIOControl使能红外模式即可；

请问第三步，应该修改COM_Write的函数的哪个位置？

If something wrong in nandflash, why wince starts ok?
No debug serial in my mainboard, so it is not easy for me to find the cause.?????
