Thank you.  Using the FT90x worked as you described. 

As an aside, is there a way to configure the FT90X MCU to accept RS232 instead of TTL/UART?  I'm interested in translating 232 signals, but will use a MAX232 chip.  However, I've read that some micros can perform this conversion.  Thanks.

Hello,

Please ensure the VNC2 Debugger/Programmer Module drivers have installed correctly.
This can be checked in device manager.
You might want to try a driver uninstall/reinstall. See FTDI_Driver_Uninstall_with_2-12-28_Install.pdf.

The other thing to do would be to disable the COM port, because the VNC2 uses the D2XX drivers rather than VCP drivers.
This would stop any other software program claiming the COM port without you knowing, which means that the D2XX interface wouldn’t be available.
This can be changed in the EEPROM using FT_Prog which would make this change permanent.
It can also be done at Windows device manager level, but the option would only exist for that particular installation.

Then ensure that the VNC2 Debugger/Programmer Module is connected to the VNC2 module/device correctly.

Can you also try programming directly within the IDE?

Vinculum/Vinculum-II are very mature products and are no longer supported by R&D and has been superseded by FT9xx.

The best solution we have is our FT90x MCU.

There are lots of other examples available:

AN_360 FT9xx Example Applications
FT90x Software Examples
FT9xx Software Examples

There are significant benefits of FT90x:

-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.

If you need any further information, please email your local support team:

Hello!

I'm developing V2DIP1-3D with VNC2 Debug Module.
But they don't work correctly...
I cannot flash a firmware via the debugger.

I tried FT_Prog and V2Prog, but both failed with errors.
Did I miss something?

BR,

Thanks so much, the response has been very helpful. Indeed, I had overlooked the need for the 47pF edge rate control capacitors.

Hello,

Yes those power connections are correct as the datasheet states, if VCC is 3V3 then 3V3OUT must also be driven with 3V3 input.

You may also want to include 47pF capacitors on the USB lines for edge rate control.
See AN_146 USB Hardware Design Guidelines for FTDI ICs for more details.

We have Development Modules available for test, evaluation and reference.

Hi,

I am integrating the FT230XQ chip into my design, and am powering VCC with 3.3V (regulated from USB_VBUS). Consequently, I followed the datasheet which states "3V3OUT on pin 8 is an input pin and should be connected to pin10". Please could you advise whether the attached schematic is correct? I should highlight that the 3.3V rail supplying VCC, VCCIO, and 3V3OUT is derived from USB_VBUS using an LDO regulator.

Thanks.

Hello,

You are already in email contact with your local support team.

Please continue to work with them for a beta ARM driver.

Best Regards,

Hi All,

I'm planning to integrate FT601 into our design to implement 32-bit FIFO interface with the Raspberry Pi via USB3.0. According to FTDI website, the D3XX drivers currently do not support ARM architecture, is that correct ? Are there any examples or is there any way that I can get the driver to work with the  Rpi?

Thank you,

The problem was caused by "FT_SetBitMode(ftHandle, 0xFF, 0x01); " I accidentally copied it from an example. This setting persists even if you close the device and open it in another progam.

Hello,

Which driver version is installed? The latest is 2.12.28.

Can you please test with our standard hardware to rule out any issues with OEM hardware?

See our Development Modules:

FT-X Breakout Modules
FT-X Development Modules

It looks like you are also into contact with our support team via email. Please continue to work with your local support team member and feel free to post any resolution here to help other users.

Best Regards,
