Hello Rakesh,

I note you have emailed into the support channel with this question as well.

The drivers you have installed are the D2XX API drivers, intended for use with custom software applications and will not present a COM port to the OS for the device.

The Virtual COM Port (VCP) driver for Linux (ftdi_sio) is currently maintained by the Linux Kernel team.
You should check if your kernel includes this driver, if it does not you can rebuild your kernel to include support for this.

Also, FTDI devices are not designed or marketed specifically for Modbus.
However, the RS485 units will connect at the correct signalling levels to a Modbus system.
Based on customer feedback:
If your modbus bus system uses ASCII framing it should be OK.
If your modbus system uses RTU framing then it is unlikely to work.

Hello,

Rudolph is correct you should use a GPIO pin on your board fro the PD signal.

Hello,

Unfortunately it is not possible to bridge UART connections through the IC between devices.

Hello,

SafeGuard-IT is a very old application that’s no longer supported by R&D.
It was developed many years ago in 2007.
Note ChipID and SafeGuard are two different things.

SafeGuard-IT uses the Chip ID which can be found here:

http://www.ftdichip.com/Support/SoftwareExamples/FTDIChip-ID.htm

This Chip ID DLL is used with the D2XX Drivers.

It’s better to develop your own code using FTDIChip-ID.

There is another option to avoid using the Chip ID DLL which means even less dependency on our DLLs:
The FTChipID cannot be read from the FTD2XXX library directly as standard.
There is an NDA option available where we can provide the memory location of the raw FTChipID in EEPROM.
However, note that the FTDIChip-ID.dll does some additional manipulation of this EEPROM data, so the dll vs direct EEPROM read might not match.

If you would like this information under NDA, please Contact Us.

As for your error "Insufficient space in EEPROM user data area" there is a limited amount of memory available in the EEPROM (1024 bits).
The size of the user area depends on the length of the Manufacturer, ManufacturerId, Description and SerialNumber strings programmed into the internal EEPROM. More memory space is freed up if the lengths of the information strings are shortened. The Maximum length of the Manufacturer, ManufacturerId, Description and SerialNumber strings is 48 words (1 word = 2 bytes). If all the 48 words are used, then no user area space is available.
To reduce the memory already taken up and to free up more space available to User Area, you could reduce the serial number and description strings using FT_PROG.
Also see AN_121 Accessing The EEPROM User Area Of FTDI Devices for more information.

Maybe there are other community users who can help you further.

Hello,

There are no serial communication tools available for this functionality that we are aware of.

The I2C interface must be controlled using software as mentioned in my previous post.

Discussion - Drivers / Re: VCP Latency on Mac Catalina and Big Sur
« on: October 26, 2020, 03:47:22 PM »
Hello,

We are currently working on a .dext driver for the newer versions of macOS.
My current understanding is that the Info.plist file will be used in a similar way to .kext drivers to alter latency options within the driver.

Hello,

To use I2C/SPI master with FT232H, see AN_135 FTDI MPSSE Basics and our existing MPSSE Example projects:

http://www.ftdichip.com/Support/SoftwareExamples/MPSSE.htm

There are two options to use I2C/SPI modes with the MPSSE engine:

a.            Use LibMPSSE libraries. Example code is provided with the download.
b.            Use D2XX drivers direct. Example code is shown at I2C / SPI. AN_108 Command Processor For MPSSE and MCU Host Bus Emulation Modes provides the necessary information.

Option b is the best option to use the D2XX drivers direct (no dependency on libMPSSE library).

Hello,

One way is to create custom font characters with these special characters added.

When used individually, font characters are similar to bitmap images and can be displayed with a vertex command but if you want to use the characters within text strings of standard characters, you can also use the techniques shown in this draft application note below. It is built on the simple PIC framework from BRT_AN_008  but the same technique also works on other MCUs.

Here are the links to the draft document and the beta code,

« on: October 16, 2020, 12:17:51 PM »
Hello,

Yes the FT4232H can be utilised to provide up to 4 UART connections from a single USB device, each UART connection would present its own COM port to the host machine.

Hello,

Can you please ensure the 'Load VCP' option is ticked for the device.
Please reference the attached screenshot.

Hello

Please see TN_162 Bus Powered with Power Switching Configuration which should help.

Hello,

This is strange that the serial number and description is not visible from the FT_GetDeviceInfoDetail.

Are the serial number and description visible on the Ubuntu PC?

If so it could suggest that the USB Port is already open by other software.

Note that sudo (or running as root) is required to get full access to USB.
