Hello,

There are two ftd2xx.lib files for x86 and x64.

The static .lib doesn't rely on a .dll.

Again you can reference the most recent .lib and .dll for D2xx in the 2.12.36.4 driver files.

TN_153 Instructions on Including the D2XX Driver in a Visual Studio Express 2013 Project should help you too.

Hello,

It depends if you are building a static or dynamic application.

.lib is a static library which is linked into an .exe at compile time. Only the .lib is included in the folder.
.dll is a dynamic library that is loaded at runtime. That includes a .lib for the symbols.

Hello,

You can also reference the latest version of ftd2xx.h in the latest 2.12.36.4 driver files.

Hi Yvonne,

I did the same experiment, but I could detect the second HID device successfully.
I've checked our source code and there is nowhere that is actively calling the changeInEnumeration function.
At present, I can only suspect that the possible reason is that there is something wrong with the program you are running, which leads to such strange things happening.

Could you provide us more details, so we can clarify the problem?

Best regards

Hi,

What version of LibFT4222 are you using?

if you are using an old version of the library, then there are such dependencies. But if you are using the latest version, there should be no dependencies.

Best regards

Hi,

These undefined symbols don't look familiar. The LibFT4222 examples can be build for x86 and x64 which generates a .exe. not a DLL

If the version is lower than or equal to 1.4.4. Libft4222 bases on Microsoft Visual C++ 2010 x86 and x64 Redistributable package.

Please install the below package on the target machine.

https://docs.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170


If the version is higher than or equal to 1.4.5. Microsoft Visual C++ 2010 runtime library is built in LibFt4222. The user does not need to install Microsoft Visual C++ 2010 x86 and x64 Redistributable package on the target machine.

Discussion - Software / Re: FT232HL maximum SPI Rx hz
« on: June 26, 2023, 11:33:47 AM »
Hi Terry,

The maximum SPI clock for FT232H is 30MHz. This information can be found in LibMPSSE-SPI User Guide.

Hello,

We assume this is an SPI Master application.
We have already tested this on SPI Flash and it works fine.
Maybe you are encountering some hardware or wiring trouble?
Please make sure the SPI wiring is as short as possible if you want a higher frequency.
Probing the wiring may also cause signal delay so it is not recommended.

Hello,

VNC2 may not support all USB HID class devices.

"USBHostHID" and "USBHostHID2" are only examples.
Refer to the ReadMe.txt inside the example folder.

You can refer to AN_151 Vinculum II User Guide for all API usage which may help you implement your own solution to host an NFC reader.

There may be other FTDI Community users who can help you further.

Discussion - Hardware / Re: USB to I2C Master Reference Designs?
« on: May 04, 2023, 04:48:13 PM »
Hello,

There are a few products which you can consider as a USB to I2C master.

The I2C master devices that we have are as follows.
All will require some form of application code running on the OS to control the device:

Using MPSSE and d2xx:
FT232H
See AN_135 MPSSE Basics. Also MPSSE software examples exist.
UM232H is available for test, evaluation and reference.

Using LibFT4222 and d2xx:
FT4222H
Software examples are provided with the library download.
UMFT4222EV-D is available for test, evaluation and reference.

HID class device
FT260
LibFT260 can be used with Windows, software examples are provided with the LibFT260 library download.
UMFT260EV1A is available for test, evaluation and reference.

Schematics are provided in the modules linked above.

Note that the FT602 is not an appropriate product. This is a UVC video class device with built-in I2C master interface for video device configuration, not for general I2C master usage. It's likely the FT602 is overkill if you are just looking for an USB to I2C master bridge.
