Discussion - Software / Re: Building a DLL that uses LibFT4222 and now getting "Unresolved symbol" errors
« on: July 03, 2023, 11:55:15 AM »
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.

General Discussion / Re: 1 bit shift when communicating with SPI using FT4222H
« on: June 06, 2023, 04:01:43 PM »
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.

General Discussion / Re: Could chip of VNC2 support RFID or NFC reader function?
« on: June 02, 2023, 03:56:23 PM »
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.

Best Regards,

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.

Hi,
Our LibMPSSE source code is provided on the FTDI website if you want to make changes.
https://ftdichip.com/software-examples/mpsse-projects/

You could also choose not to use LibMPSSE and use d2xx direct. (See AN_108)

Hi,

What hardware is it you are using exactly?

i ran the example and was able to change the serial number without any issues. You could try using our programming utility FT_PROG to change the serial number as an alternative. it can be found on our website here: https://ftdichip.com/utilities/.

Hello,

Unfortunately there is no update from our R&D team due to other ongoing projects and priorities.

The source code is provided so should be easy for you to rebuild.

However if you send us an email we can send you a pre-release version that we have build containing this fix.

Thanks,

VNC2 AppWiard in IDE 2.0.2 SP2 and SP3:

Per the VNC2 datasheet, pin-9 is RESET# and pin-10 is PROG# for 48-pin and 64-pin packages.

A bug has been found in the pin definition of pin-9 and pin-10 are swapped in AppWizard of the IDE.
 
This will not currently be fixed in the IDE.
