Wince 下的红外驱动，不加任何遥控协议，只是一个简单的功能测试，升级版本，等下一次更新在发给大家，好了 废话少说现在告诉大家方法。
本产品以ok6410为例，介绍如何新建和修改ce6下的红外驱动和红外测试程序
只要按照步骤执行下去，即可建立一个红外驱动。并做驱动介绍。完成驱动开发的准备工作。
硬件平台：飞凌OK6410-A
操作系统：飞凌光盘中的BSP，WINCE6.0
编译工具：VS2005 + WINCE6.0 + BSP
在上述所有工具安装完成后，直接用BSP的快捷方式打开。
驱动主要在文件夹PLATFORM/SMDK6410/src/drivers下
建立过程：
1.在drivers文件夹上点击右键，选择add->New Source Subproject->WCE Dynamic-Link Library在name框中输入IRS，下一步。
选择A simple Windows Embedded CE DLL subproject完成。
2，打开PLATFORM/SMDK6410/src/drivers/IRS文件夹
里面已经替你建好了如下文件：makefile，source，StdAfx.cpp，StdAfx.h，XXX.cpp，XXX.def
用文本编辑器打开XXX.def文件，添加如下代码
LIBRARY IRS_DRV
EXPORTS IRS_Init
IRS_Deinit
IRS_Open
IRS_Close
IRS_Read
IRS_Write
IRS_Seek
IRS_PowerDown
IRS_PowerUp
IRS_IOControl
3.打开IRS.cpp文件加入如下代码：
#include "stdafx.h"
#include <s3c6410.h>
#include <DrvLib.h>
#include <winuser.h>
#include "IRS.h"
// GPIO virtual address
static volatile S3C6410_GPIO_REG *v_pIOPregs ;
//----------------------------------------------------------------------------//
//
DLL entry
//
//----------------------------------------------------------------------------//
BOOL APIENTRY DllMain(HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved) {
switch (ul_reason_for_call) {
case DLL_PROCESS_ATTACH:
OutputDebugString(L"\nIRS - DLL_PROCESS_ATTACH\n");
RETAILMSG(1,(TEXT("IRS - DLL_PROCESS_ATTACH\n")));
break;
case DLL_PROCESS_DETACH:
//RETAILMSG(1,(TEXT("LED - DLL_PROCESS_DETACH\n")));
//OutputDebugString(L"LED - DLL_PROCESS_DETACH\n");
break;
case DLL_THREAD_ATTACH:
//RETAILMSG(1,(TEXT("LED - DLL_THREAD_ATTACH\n")));
//OutputDebugString(L"LED - DLL_THREAD_ATTACH\n");
break;
case DLL_THREAD_DETACH:
//RETAILMSG(1,(TEXT("LED - DLL_THREAD_DETACH\n")));
//OutputDebugString(L"LED - DLL_THREAD_DETACH\n");
break;
default:
break;
}
return TRUE;
}
//----------------------------------------------------------------------------//
//
IRS initial
//
//----------------------------------------------------------------------------//
DWORD IRS_Init(LPCTSTR pContext, LPCVOID lpvBusContext) {
//Virtual address mapping
v_pIOPregs = (volatile S3C6410_GPIO_REG*)DrvLib_MapIoSpace(S3C6410_BASE_REG_PA_GPIO,
sizeof(S3C6410_GPIO_REG),
FALSE);
return 1;
}
//----------------------------------------------------------------------------//
//
IRS deinit
//
//----------------------------------------------------------------------------//
BOOL IRS_Deinit(DWORD hDeviceContext) {
VirtualFree((PVOID)v_pIOPregs, 0, MEM_RELEASE);
v_pIOPregs = NULL;
return TRUE;
}
//----------------------------------------------------------------------------//
//
IRS open
//
//----------------------------------------------------------------------------//
DWORD IRS_Open(DWORD hDeviceContext, DWORD AccessCode, DWORD ShareMode) {
OutputDebugString(L"IRS - IRS Open\n");
return 1;
}
//----------------------------------------------------------------------------//
//
IRS close
//
//----------------------------------------------------------------------------//
BOOL IRS_Close(DWORD hOpenContext) {
OutputDebugString(L"IRS - IRS Close\n");
return TRUE;
}
//----------------------------------------------------------------------------//
//
IRS read
//
//----------------------------------------------------------------------------//
DWORD IRS_Read(DWORD hOpenContext, LPVOID pBuffer, DWORD Count) {
return 1;
}
//----------------------------------------------------------------------------//
//
IRS write
//
//----------------------------------------------------------------------------//
DWORD IRS_Write(DWORD hOpenContext, LPCVOID pBuffer, DWORD Count) {
return 1;
}
//----------------------------------------------------------------------------//
//
IRS power up
//
//----------------------------------------------------------------------------//
VOID IRS_PowerUp(DWORD hDeviceContext) {
}
//----------------------------------------------------------------------------//
//
IRS down
//
//----------------------------------------------------------------------------//
VOID IRS_PowerDown(DWORD hDeviceContext) {
}
//----------------------------------------------------------------------------//
//
IRS seek
//
//----------------------------------------------------------------------------//
DWORD IRS_Seek(DWORD hOpenContext, long Amount, DWORD Type) {
return 0;
}
//----------------------------------------------------------------------------//
//
IRS IO control
//
//----------------------------------------------------------------------------//
BOOL IRS_IOControl(DWORD Handle,
DWORD dwIoControlCode,
PBYTE pInBuf,
DWORD nInBufSize,
PBYTE pOutBuf,
DWORD nOutBufSize,
PDWORD pBytesReturned) {
switch (dwIoControlCode) {
case IOCTL_COL0:
v_pIOPregs->GPECON &= (~0xf); //直接将gpe1配置成输入，然后读取他的状态，放到pOutBuf[0]
if ((v_pIOPregs->GPEDAT) & (0x01<< 1))
{
pOutBuf[0] = 1;
}
else {
pOutBuf[0] = 0;
}
break;
return TRUE;
}
}
4.在IRS.h中添加
#define IOCTL_COL0
0x1000
5.添加C:\WINCE600\PLATFORM\SMDK6410\FILES\platform.reg
;================ IRS ===========
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\IRS]
" refix"="IRS"
"Dll"="IRS.dll"
"Order"=dword:35
"Index"=dword:1
6.添加C:\WINCE600\PLATFORM\SMDK6410\FILES\platform.bib
;------------- IRS Driver -------------------------------------------------------------
;IF BSP_NOIRS !
IRS.dll
$(_FLATRELEASEDIR)\IRS.dll NK SHK
;ENDIF BSP_NOIRS !
;---------------------------------------------------------------------------------------
7.打开PLATFORM/SMDK6410/src/drivers/IRS文件夹，打开irs文件夹，找到sourse文件，用一下代码替换原有代码：
!if 0

!endif
!if 0

!endif
!if "$(BSP_NOLED)" == "1"
SKIPBUILD=1
!endif
RELEASETYPE=PLATFORM
PREPROCESSDEFFILE=1
TARGETNAME=IRS
SOURCES= \
IRS.cpp \
TARGETTYPE=DYNLINK

CDEFINES=$(CDEFINES) -DLED_EXPORTS

8.然后clean sysgen
应用程序编写
新建一个工程，取名IRS，然后在，窗体中创建一个如图所示的窗体：
在
IRSDlg.cpp中添加如下代码：
// IRSDlg.cpp : implementation file
//
#include
"stdafx.h"
#include
"IRS.h"
#include
"IRSDlg.h"
#ifdef
_DEBUG
#define
new
DEBUG_NEW
#endif
#define
IOCTL_COL0
0x1000
// CIRSDlg dialog
CIRSDlg::CIRSDlg(CWnd* pParent
/*=NULL*/)
: CDialog(CIRSDlg::IDD, pParent)
{
m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
}
void
CIRSDlg: oDataExchange(CDataExchange* pDX)
{
CDialog:oDataExchange(pDX);
}
BEGIN_MESSAGE_MAP(CIRSDlg, CDialog)
#if
defined(_DEVICE_RESOLUTION_AWARE) && !defined(WIN32_PLATFORM_WFSP)
ON_WM_SIZE()
#endif
//}}AFX_MSG_MAP
ON_BN_CLICKED(IDC_BUTTON1, &CIRSDlg::OnBnClickedButton1)
END_MESSAGE_MAP()
// CIRSDlg message handlers
BOOL
CIRSDlg::OnInitDialog()
{
CDialog::OnInitDialog();
// Set the icon for this dialog. The framework does this automatically
// when the application's main window is not a dialog
SetIcon(m_hIcon, TRUE);
// Set big icon
SetIcon(m_hIcon, FALSE);
// Set small icon
// TODO: Add extra initialization here
return
TRUE; // return TRUE unless you set the focus to a control
}
#if
defined(_DEVICE_RESOLUTION_AWARE) && !defined(WIN32_PLATFORM_WFSP)
void CIRSDlg::OnSize(UINT /*nType*/, int /*cx*/, int /*cy*/)
{
if (AfxIsDRAEnabled())
{
DRA::RelayoutDialog(
AfxGetResourceHandle(),
this->m_hWnd,
DRA::GetDisplayMode() != DRA: ortrait ?
MAKEINTRESOURCE(IDD_IRS_DIALOG_WIDE) :
MAKEINTRESOURCE(IDD_IRS_DIALOG));
}
}
#endif
void
CIRSDlg::OnBnClickedButton1()
{
HANDLE
hLed;
CString
str1;
int
hot = 0;
hLed = CreateFile(TEXT("IRS1:"),GENERIC_READ|GENERIC_WRITE,0,NULL,OPEN_EXISTING,0,NULL);
if (hLed == INVALID_HANDLE_VALUE)
{
printf ("can't open IRS1\r\n");
}
else
{
printf ("\rOpen IRS1\r\n");
}
while(1){
DWORD
dwReturn = 0;
DeviceIoControl(hLed,
IOCTL_COL0,
NULL,
sizeof(DWORD),
&dwReturn,
0,
NULL,
NULL);
if (dwReturn){
//SetDlgItemTextW(IDC_EDIT1,str1);
}else{
hot++;
str1.Format(L"%d",hot);
SetDlgItemTextW(IDC_EDIT1,str1);
}
Sleep(100);
}
}
然后编译，将测试程序下载到开发板中，会看到当我们打开测试程序，点击开始读取后，按下手中遥控器的按键会有键值的增加，还有一个现象就是，当我们打开测试程序，测试的时候，会感觉开发板很卡，原因是我们用的是查询的方式，所以占用的系统资源很大，故，此程序仅供参考！！！！！ |
