使用using FTD2XX_NET;库帮我写一个C#代码：连接两个FT4222H设备进行SPI通信，一个FT4222H做从机，另外一个FT4222H做主机，使用模式0进行通信

在C#中，使用FTD2XX.NET库连接FT4222H设备进行SPI通信，首先需要安装Ftdi.FT4222Driver NuGet包。下面是一个基本的例子展示了如何设置和配置从机和主机之间的SPI通信。注意，这个例子假设你已经包含了必要的命名空间并初始化了硬件。

using System;
using FTDI.FT4222Driver;

class Program
{
    static void Main()
    {
        // 创建主机设备实例
        FTDevice hostDevice = new FTDevice("COM1"); // 替换为实际的串口号

        try
        {
            // 设置主机设备为SPI模式
            if (hostDevice.SetBitMode(SPIChannel.CHANNEL0, BitModeEnum.BITMODE_SPI, SPIOrderEnum.MSBFirst))
            {
                Console.WriteLine("Host device set to SPI mode 0 successfully.");
            }
            else
            {
                Console.WriteLine("Failed to set host device to SPI mode 0.");
                return;
            }

            // 创建从机设备实例
            FTDevice slaveDevice = new FTDevice("COM2"); // 替换为实际的串口号

            // 设置从机设备地址（通常在SPI器件中有固定的从机地址）
            byte slaveAddress = 0x7F; // 根据设备手册设定，这里假设为默认地址
            if (slaveDevice.ConfigurePins(slaveAddress, PinDirectionEnum.DIRECTION_INPUT | PinDirectionEnum.DIRECTION_OUTPUT))
            {
                Console.WriteLine($"Setting slave address to {slaveAddress}.");
            }
            else
            {
                Console.WriteLine("Failed to configure slave device address.");
                return;
            }

            // 发送数据到从机
            byte[] sendData = { 0x01, 0x02, 0x03 }; // 示例数据
            if (hostDevice.WriteData(SPIChannel.CHANNEL0, sendData))
            {
                Console.WriteLine("Sent data to slave device.");
            }
            else
            {
                Console.WriteLine("Failed to send data.");
            }

            // 接收数据回主机
            byte[] receiveBuffer = new byte[sendData.Length];
            int bytesRead = hostDevice.ReadData(SPIChannel.CHANNEL0, receiveBuffer, sendData.Length);
            if (bytesRead > 0)
            {
                Console.WriteLine($"Received {bytesRead} bytes from slave: {BitConverter.ToString(receiveBuffer)}");
            }
            else
            {
                Console.WriteLine("Failed to read data from slave device.");
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Error occurred: {ex.Message}");
        }
        finally
        {
            // 关闭设备
            hostDevice.Close();
            slaveDevice.Close();
        }
    }
}
