Introduction

How to write C# programs using the new DLL starting from the old DLL.

Introduction

There are some major differences between the two DLLs.

HANDLE m_handle = 0;

CyUSBDevice TE_USB_FX2_USBDevice = null;
USBDeviceList USBdevList = new USBDeviceList(CyConst.DEVICES_CYUSB);

Tip
The handles are internally managed by CyUSBCyAPI.dll lib and there is no need to expose them to the user.
Tip
CyUSBDevice TE_USB_FX2_USBDevice take the place of handles for C# programmers.

cout << endl << TE0300_ScanCards() << endl;

int NumberOfCardAttached = TE_USB_FX2.TE_USB_FX2.TE_USB_FX2_ScanCards(ref USBdevList);
Console.WriteLine(" {0} ", NumberOfCardAttached);

TE0300_Open(&m_handle, 0)!=0

TE_USB_FX2.TE_USB_FX2.TE_USB_FX2_Open
(ref TE_USB_FX2_USBDevice, ref USBdevList, 0) == false

Tip
titleTE_USB_FX2_Open()
In the code, it is possible to call TE_USB_FX2_Open() where TE0300_Open() is used.
Note
titleTE_USB_FX2_Open() act as Close() for other TE USB handles already open

When a new handle to the device driver is open (TE_USB_FX2_Open() run successfully) other internal handles (inside USBDeviceList) are automatically closed by TE_USB_FX2_Open() function. No more than one handle can be active on the same time. It is a behavior inherithed by CyAPI.dll Open() function. For this reason, TE_USB_FX2_Close() function is almost useless.

Note
titleTE_USB_FX2_Open() as SelectCard()
TE_USB_FX2_Open(TE_USB_FX2_USBDevice, USBdevList, x) acts more as a SelectCard() function because the list of USB devices is already created in USBdevList. TE_USB_FX2_USBDevice is the selected device number x (0 in this case).

TE0300_Open(&m_handle, 1)!=0

TE_USB_FX2.TE_USB_FX2.TE_USB_FX2_Open
(ref TE_USB_FX2_USBDevice, ref USBdevList, 1) == false

TE0300_Close(&m_handle);

TE_USB_FX2.TE_USB_FX2.TE_USB_FX2_Close
(ref USBdevList USBdevListToDispose);

 

Warning

In the code, it is not recommended to call TE_USB_FX2_Close() where TE0300_Close() is used. This function differs from its homonym of the previous TE0300DLL.dll in that it does not close a Handle but disposes (erases) all USB devices in the list USBdevList.

The reason of this behavior is due to the CyUSB.dll as explained by Cypress document CyUSB.NET.pdf, pages 132-133 and pages 139-140: "You should never invoke the Dispose() method of a USBDevice directly. Rather, the appropriate technique is to call the Dispose() method of the USBDeviceList object that contains the USBDevice objects".

ref reply, ref reply_length, TIMEOUT_MS)
