50高分奖励能解决我的问题者

各位大虾:本人想用DriverStudio进行并行口EPP模式的WDM编程,选总线(bus)为none生成程序框架,我试图对程序更改,但不知对不对,请指教:

void ParportEppModeDevice::SerialWrite(KIrp I)
{
t << \"Entering ParportEppModeDevice::SerialWrite, \" << I << EOL;
NTSTATUS status = STATUS_SUCCESS;

KIoRange   m_ParPortIos;
NTSTATUS status1 = m_ParPortIos.Initialize(
0x378,  // LPT1 Bus address
  TRUE,  //InCpuIoSpace
8,      // Device size
TRUE  // Map to system space
  );
#define CONTROL 2  //(37A)
#define ADDRESS 3  //(37B)
#define EDATA   4  //(37C)

    m_ParPortIos.outb(CONTROL,0x80);


// Declare a memory object
// KMemory Mem(I.Mdl());
// Use the memory object to create a pointer to the caller\'s buffer
// PUCHAR pBuffer = (PUCHAR) Mem.MapToSystemSpace();

ULONG   dwTotalSize = I.WriteSize(CURRENT);
ULONG   dwBytesSent = 0;


    m_ParPortIos.outb(ADDRESS,addr); //?????????????????
    m_DeviceIos.outb(EDATA,data); //????????????????????
// TODO: If the write can be satisfied immediately, set the Information
// and Status fields now, then call NextIrp to complete this IRP
// and start processing the next IRP in the queue.

// TODO: If the device cannot accept all of the data yet, initiate a
// request to the physical device here, and defer the Information,
// Status, and NextIrp handling until the hardware indicates that
// the write is complete.  Typically, this might be handled in a
// DPC that is called after the hardware finishes transferring
// the data.

// TODO: To satisfy the write now, transfer data to the device
// from caller\'s buffer at \"pBuffer\".  Then, indicate how much
// data was transferred:

I.Information() = dwBytesSent;

I.Status() = status;


// PnpNextIrp completes this IRP and starts processing
// for the next IRP in the driver managed queue.
// TODO: The Wizard creates a single queue for all Irps.
// If you have created additional queues, select
// the appropriate queue for this Irp here.
m_DriverManagedQueue.PnpNextIrp(I);
}

其中的   m_ParPortIos.outb(ADDRESS,addr); //?????????????????
    m_DeviceIos.outb(EDATA,data); //????????????????????
部分更不知怎么处理,请指教,高分相谢.

我看过,可就是不理解,你看懂了吗?
若能指教,一定重分奖励.

你说的是地址和数据的输入吧,在KIrp中有writedestsource(具体记不清了),可以将应用层的数据通过irp放到里面,你读里面的数据写到端口就是了.
(一般端口的读写都用Buffer方式)

多找贴子看吧,本站上有很多关于并口的贴子,我也是新手

好兄弟,你的并口驱动不是做好了吗,将源码Email给我参考参考吧，先奖你１０分，收到后再奖４０分如何？

能否也给我一份？我也给分！

各位大虾,这样行不行啊

我也想知道这样行不行，因为我想改成串口的读写。不知有没有人调试过这个程序？

兄弟，你这几条语句不应该放在这里

KIoRange m_ParPortIos;
NTSTATUS status1 = m_ParPortIos.Initialize(
0x378, // LPT1 Bus address
TRUE, //InCpuIoSpace
8, // Device size
TRUE // Map to system space
);
这怎么能够放在 Write（）韩树中呢？应该放在OnStartDevice中分配一次就够了，否则每次写的时候都重新分配！

你说的有道理,谢谢!可惜没法给你分了,真不好意思.
