Класс-обёртка для работы с библиотекой FTD2XX на Visual Basic .NET
Предлагается класс-обёртка для работы с библиотекой ftd2xx.dll, которая позволяет управлять различными микросхемами фирмы FTDI.
За основу данного кода взят проект класса-обёртки на языке C# с официального сайта FTDI. По сравнению с данным примером, классу был придан более объектно-ориентированный стиль. Кроме того, класс был разделён на два частичных (partial) класса. В первой части класса Ftdi находится базовая функциональность, которая чаще всего нужна для работы с микросхемами FTDI. Во второй части содержится код, необходимый для работы с ЭСППЗУ микросхем FTDI.
Замечу, что пришлось все члены типа IntPtr переделать на тип Integer. Это связано с тем, что в Visual Studio 2019 при работе с IntPtr возникает ошибка BC30657. Микрософт до сих пор не исправила её (Visual Studio 2019 версия 16.6.3), хотя они в курсе проблемы.
При этом при вызове нативных функций, которые требуют тип IntPtr, получить его можно двумя способами: либо создавая новый объект, инициализируя его значением целого числа integerValue:
New IntPtr(integerValue)
Либо через приведение типов:
CType(integerValue, IntPtr)
Также можно обратить внимание на вызов делегатов, которые повсеместно встречаются в коде при обращении к нативным функциям в библиотеке. При получении делегата по указателю, его можно вызвать тоже двумя способами. Например, в методе открытия устройства OpenByIndex() встречается такое:
Dim tFT_Open As OpenDelegate = CType(Marshal.GetDelegateForFunctionPointer(New IntPtr(pFT_Open), GetType(OpenDelegate)), OpenDelegate) 'получение делегата по указателю status = tFT_Open.Invoke(index, ftHandle) 'использование делегата
Это эквивалентно более краткой записи, когда можно опустить указание метода Invoke() и сразу записать аргументы, передаваемые делегату (или пустые скобки, если аргументы не передаются):
status = tFT_Open(index, ftHandle)
Нативные (родные) функции, методы – в данном контексте имеются в виду функции Windows, для выполнения которых необходимо обратиться к Windows API. Это функции, которые выполняются не средой .NET Framework, а непосредственно операционной системой. В противоположность нативному коду, существует т.н. «управляемый» код. Он выполняется под управлением фреймворка .NET, а точнее CLR – общеязыковой исполняющей среды. Нативный код также называют «неуправляемый».
В данном классе используются лишь три нативных метода, которые объявляются с атрибутом DllImport в самом начале класса Ftdi. Все они берутся из динамически загружаемой библиотеки Windows kernel32.dll.
Первая часть класса Ftdi: Базовые функции для работы с м/сх FTDI

Практически такая же большая по объёму кода вторая часть класса Ftdi. Она содержит большое число структур, которые описывают то, каким образом хранятся данные в ПЗУ различных типов микросхем FTDI. Если вы не планируете работать с ПЗУ своей микросхемы, то можно просто не использовать эту вторую часть класса. Тогда в первой части класса необходимо будет удалить ссылку на метод FindEeFunctionPointers() в конструкторе. Больше нигде эти две части класса Ftdi между собой не пересекаются.
Вторая часть класса Ftdi: Функции для работы с ПЗУ м/сх FTDI
Imports System.Runtime.InteropServices

Использовать данный класс можно, например, так:
Dim ft as New FTD2XX_NET.Ftdi()
Console.WriteLine($"Number of connected FTDI devices = {ft.GetNumberOfDevices()}")
ft.OpenByIndex(0)
Console.WriteLine($"Description = {ft.GetDescription()}")
Console.WriteLine($"Serial number = {ft.GetSerialNumber()}")
ft.Close()
Чтобы всё работало, в системе должен быть установлен драйвер для устройства FTDI, а также в заданной директории (путь задаётся в конструкторе класса Ftdi) должна находиться dll-ка FTD2XX.DLL, которую необходимо скачать с сайта производителя.
Понятно, что данный код несовершенен, и я буду его периодически обновлять. Все самые свежие обновления данного класса Ftdi будут размещаться в репозитории на GitHub.
