Hello Kaspro,

The FT90x will handle this better than VNC2.

You are also in contact with our support team on this issue via email.
Feel free to post any resolution or information from the email support to help other forum users.

Hello Jeff,

Power should always be applied to the device when in use.
VCC and VCCIO should be applied at the same time.

When the board is powered off, do not apply any voltages to the IC pins.
There might be some current draw but this is not specified because the device can be in unknown states.

It may be advisable to add a buffer or MOSFET gated with PWREN# to avoid such behaviour.

FTDI Community

Hello,

Yes the FT90x can be used with an external HUB allowing for BOMs and HID class hosting.

Hello,

Vinculum and Vinculum-II are quite old solutions and it don’t seem to work with a lot of newer devices due to changing designs. Note that is only a Full Speed (12Mbits/second) controller.
These mature products have not had any development for years and have been superseded by FT9xx.

The best option would be to use the FT90x MCU, however note that this only includes 1 x USB Host and 1 x USB Device controller.
This uses a USB 2.0 Hi-Speed (480Mb/s) controller.

You could take a look at the following examples to host HID class devices:

AN_360 FT9xx Example Applications

There are significant benefits of FT90x over VNC2:

-Eclipse based IDE
-Source code for API drivers is provided
-Significant performance improvement
-Actively in development by R&D
-Improved documentation and software examples

We provide FT9xx Development Modules and a free FT9xx Toolchain for custom application development.

Hello,

There are plenty of examples available with the IDE.

Take a look at V2DAP:

C:\Users\Username\Documents\FTDI\Firmware\Samples\V2.0.2-SP2\VNC1L\V2DAP

This would allow a BOMs class device on Port 2 and HID class device on Port1.
You could customise the firmware to meet your needs or create your own custom firmware.

Also refer to the following documents:

Vinculum Firmware User Manual
AN_176 - Vinculum Comparison of VDAP and V2DAP

There may be other users on the forum who could help you further.

« on: April 01, 2020, 04:47:12 PM »
Hello,

Hopefully someone on the community forum has experience with the Aardvark Adapter.

You can refer to our documentation for further information:

AN_365 FT9xx API Programmers Manual
BRT_AN_020 FT90X Revision C User Manual

You must call spi_enable_interrupt in order to use interrupts with SPI.

Hello,

Unfortunately I did not have a chance to before the UK (where I am based) went into lockdown due to the COVID-19 pandemic.
As such I cannot get into the office to acquire the correct EVE board to try this on.

Can you try taking logic captures of the SPI lines? you can decode these and see if the correct data is getting sent to the EVE IC for the second larger font example.

BRT Community

Hi,

could you reproduce the error? Any news regarding this issue?

Thanks,
Santiago

Hello,

The SPI slave example in AN_360 is designed to work with the SPI master examples also in AN_360.

Check the 'Aardvark I2C/SPI Host Adapter' SPI master settings and either modify the example code or create your own custom code to communicate with this device.

Hello,

The FT602 is designed to transfer uncompressed YUV422 video data. All of our FT602 resources including software examples can be found on the product page:

Hello,

Please see AN_428 D2XX EEPROM Programming Examples for some useful information.

Also refer to the D2XX Programmer's Guide.

FT_EEPROM_Read and FT_EEPROM_Program must be used with the FT_X Series.

If you send us an email I can send a simple code example. This forum is limited to 20000 characters so couldn't post it here.
