windows下gd芯片与FM17550串口通讯demo

可以使用以下步骤在Windows下使用GD芯片与FM17550进行串口通讯：

1.首先，确保您的计算机上已经安装了串口驱动程序，并且可以正常使用。

2.使用串口连接GD芯片和FM17550。请注意，确保两个设备的波特率和数据位数等设置是相同的。

3.编写串口通讯程序，您可以使用C、C++、Python等语言编写。以下是一个简单的C++程序示例：

#include <iostream>
#include <windows.h>

int main()
{
    HANDLE hSerial;
    DCB dcbSerialParams = { 0 };
    COMMTIMEOUTS timeouts = { 0 };
    DWORD dwBytesWritten, dwBytesRead;
    char* lpBuffer = "Hello, World!";
    char lpReadBuffer[100];

    hSerial = CreateFile("COM3", GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);

    if (hSerial == INVALID_HANDLE_VALUE) {
        std::cout << "Error: Cannot open serial port." << std::endl;
        return 1;
    }

    dcbSerialParams.DCBlength = sizeof(dcbSerialParams);

    if (!GetCommState(hSerial, &dcbSerialParams)) {
        std::cout << "Error: Cannot get serial port parameters." << std::endl;
        return 1;
    }

    dcbSerialParams.BaudRate = CBR_9600;
    dcbSerialParams.ByteSize = 8;
    dcbSerialParams.StopBits = ONESTOPBIT;
    dcbSerialParams.Parity = NOPARITY;

    if (!SetCommState(hSerial, &dcbSerialParams)) {
        std::cout << "Error: Cannot set serial port parameters." << std::endl;
        return 1;
    }

    timeouts.ReadIntervalTimeout = 50;
    timeouts.ReadTotalTimeoutConstant = 50;
    timeouts.ReadTotalTimeoutMultiplier = 10;
    timeouts.WriteTotalTimeoutConstant = 50;
    timeouts.WriteTotalTimeoutMultiplier = 10;

    if (!SetCommTimeouts(hSerial, &timeouts)) {
        std::cout << "Error: Cannot set serial port timeouts." << std::endl;
        return 1;
    }

    if (!WriteFile(hSerial, lpBuffer, strlen(lpBuffer), &dwBytesWritten, NULL)) {
        std::cout << "Error: Cannot write to serial port." << std::endl;
        return 1;
    }

    if (!ReadFile(hSerial, lpReadBuffer, sizeof(lpReadBuffer), &dwBytesRead, NULL)) {
        std::cout << "Error: Cannot read from serial port." << std::endl;
        return 1;
    }

    std::cout << "Received: " << lpReadBuffer << std::endl;

    CloseHandle(hSerial);

    return 0;
}

4.根据您的实际情况修改程序中的串口号、波特率等参数，并编译运行程序。
