好的,以下是简单的步骤:
1. 打开VS2010,创建一个新的Win32控制台应用程序项目
2. 在“解决方案资源管理器”中,右键单击项目名称,选择“添加”->“新建项”,命名为“SerialPortHelper.cpp”
3. 在“解决方案资源管理器”中,右键单击项目名称,选择“属性”,在“配置属性”中选择“常规”,将“字符集”选择为“使用多字节字符集”
4. 在“解决方案资源管理器”中,右键单击项目名称,选择“属性”,在“配置属性”中选择“C/C++”,在“常规”中将“附加包含目录”添加“C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include”
5. 在“解决方案资源管理器”中,右键单击项目名称,选择“属性”,在“配置属性”中选择“链接器”,在“常规”中将“附加库目录”添加“C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\lib”
6. 在“解决方案资源管理器”中,右键单击项目名称,选择“属性”,在“配置属性”中选择“链接器”,在“输入”中将“附加依赖项”添加“kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib”
7. 在“解决方案资源管理器”中,双击“SerialPortHelper.cpp”打开文件,输入以下代码:
```c++
#include <windows.h>
#include <stdio.h>
int main()
{
HANDLE hComm;
BOOL fSuccess;
DWORD dwEvtMask;
char lpBuffer[1024];
DWORD lpNumberOfBytesRead;
DCB dcbSerialParams = {0};
COMMTIMEOUTS timeouts = {0};
// 打开串口
hComm = CreateFile("COM1",
GENERIC_READ | GENERIC_WRITE,
0,
NULL,
OPEN_EXISTING,
0,
NULL);
if (hComm == INVALID_HANDLE_VALUE)
{
printf("Error opening serial port\n");
return 1;
}
// 配置串口参数
dcbSerialParams.DCBlength = sizeof(dcbSerialParams);
fSuccess = GetCommState(hComm, &dcbSerialParams);
if (!fSuccess)
{
printf("Error getting current serial port state\n");
CloseHandle(hComm);
return 1;
}
dcbSerialParams.BaudRate = CBR_9600;
dcbSerialParams.fBinary = TRUE;
dcbSerialParams.fParity = FALSE;
dcbSerialParams.fOutxCtsFlow = FALSE;
dcbSerialParams.fOutxDsrFlow = FALSE;
dcbSerialParams.fDtrControl = DTR_CONTROL_ENABLE;
dcbSerialParams.fDsrSensitivity = FALSE;
dcbSerialParams.fTXContinueOnXoff = TRUE;
dcbSerialParams.fOutX = FALSE;
dcbSerialParams.fInX = FALSE;
dcbSerialParams.fErrorChar = FALSE;
dcbSerialParams.fNull = FALSE;
dcbSerialParams.fRtsControl = RTS_CONTROL_ENABLE;
dcbSerialParams.fAbortOnError = FALSE;
dcbSerialParams.wReserved = 0;
dcbSerialParams.XonLim = 2048;
dcbSerialParams.XoffLim = 512;
dcbSerialParams.ByteSize = 8;
dcbSerialParams.Parity = NOPARITY;
dcbSerialParams.StopBits = ONESTOPBIT;
fSuccess = SetCommState(hComm, &dcbSerialParams);
if (!fSuccess)
{
printf("Error setting serial port state\n");
CloseHandle(hComm);
return 1;
}
// 配置超时时间
timeouts.ReadIntervalTimeout = 50;
timeouts.ReadTotalTimeoutConstant = 50;
timeouts.ReadTotalTimeoutMultiplier = 10;
timeouts.WriteTotalTimeoutConstant = 50;
timeouts.WriteTotalTimeoutMultiplier = 10;
fSuccess = SetCommTimeouts(hComm, &timeouts);
if (!fSuccess)
{
printf("Error setting serial port timeouts\n");
CloseHandle(hComm);
return 1;
}
// 监听串口事件
fSuccess = SetCommMask(hComm, EV_RXCHAR);
if (!fSuccess)
{
printf("Error setting serial port event mask\n");
CloseHandle(hComm);
return 1;
}
// 循环读取串口数据
while (1)
{
fSuccess = WaitCommEvent(hComm, &dwEvtMask, NULL);
if (!fSuccess)
{
printf("Error waiting for serial port event\n");
CloseHandle(hComm);
return 1;
}
if (dwEvtMask & EV_RXCHAR)
{
fSuccess = ReadFile(hComm, lpBuffer, sizeof(lpBuffer), &lpNumberOfBytesRead, NULL);
if (!fSuccess)
{
printf("Error reading from serial port\n");
CloseHandle(hComm);
return 1;
}
printf("%.*s", lpNumberOfBytesRead, lpBuffer);
}
}
// 关闭串口
CloseHandle(hComm);
return 0;
}
```
8. 保存并编译程序,生成exe文件
9. 使用串口连接设备后,打开cmd,切换到exe文件所在的目录,输入文件名并回车即可运行
以上代码只是一个简单的示例,可以根据实际需求进行修改和扩展。
