FTDI.FTD2XX_NET 1.3.3

FTD2XX_NET

A .NET wrapper for the FTD2XX DLL for FTDI devices. This package allows you to communicate with FTDI devices from your .NET applications.

Description

This is a .NET wrapper for the FTD2XX.DLL, which is used to communicate with FTDI's USB to serial converters and other devices. It provides a convenient managed API to access FTDI driver functionality from C# and other .NET languages.

Requires: The FTD2XX.DLL must be installed on the system. You can download the drivers from the FTDI website.

Requirements

• Operating System: Windows 10 or later (x86 or x64)
• FTDI Drivers: FTD2XX.DLL must be installed and registered in System32 or application folder.

Installation

Install via the NuGet Package Manager Console:

Install-Package FTDI.FTD2XX_NET

Or via the .NET CLI:

dotnet add package FTDI.FTD2XX_NET

Quick Start

using System;
using FTD2XX_NET;

class Program
{
    static void Main()
    {
        var ftdi = new FTDI();
        uint deviceCount = 0;
        var status = ftdi.GetNumberOfDevices(ref deviceCount);

        if (status == FTDI.FT_STATUS.FT_OK && deviceCount > 0)
        {
            Console.WriteLine($"Found {deviceCount} device(s).");
            ftdi.OpenByIndex(0);
            ftdi.SetBaudRate(115200);

            var dataToWrite = System.Text.Encoding.ASCII.GetBytes("Hello FTDI");
            uint bytesWritten = 0;
            ftdi.Write(dataToWrite, dataToWrite.Length, ref bytesWritten);

            var readBuffer = new byte[256];
            uint bytesRead = 0;
            ftdi.Read(readBuffer, (uint)readBuffer.Length, ref bytesRead);

            var response = System.Text.Encoding.ASCII.GetString(readBuffer, 0, (int)bytesRead);
            Console.WriteLine($"Received: {response}");

            ftdi.Close();
        }
        else
        {
            Console.WriteLine("No FTDI devices found or failed to enumerate.");
        }
    }
}
