Discussion - Drivers / Re: windows driver installation
« on: February 12, 2021, 11:29:29 AM »
Hello,

For Windows 10 the easiest way to install the driver is via the setup executable (in the comments column on the drivers download page).

Here is the direct link:
https://www.ftdichip.com/Drivers/CDM/CDM21228_Setup.zip

Please download this file and unzip to give an exe file. Then, whilst keeping your device disconnected from the USB port, run the exe installer and follow the install wizard. Once complete, you can connect the USB plug and your cable will finish installing.

A Windows 10 Installation Guide is also available:

Hello,

Unfortunately we do not have much experience with Python here at FTDI.

However the ssoMap value is denoted as a uint8 in the LibFT4222 User guide, and I had a look at the python ctypes library, does changing this variable from a c_uint to a c_uint8 prevent the FT_INVALID_PARAMETER from returning?

Discussion - Hardware / Re: FTDI C232HD-DDHSP-0 MATLAB SPI
« on: February 10, 2021, 04:31:17 PM »
Hello,

Unfortunately we don’t have any support for MATLAB.

However there may be other FTDI Community users who can help you.

As for SPI Master communication with FTDI C232HD-DDHSP-0 (contains FT232H) see the following information:

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

https://ftdichip.com/software-examples/mpsse-projects/

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. [urlhttp://www.ftdichip.com/Support/Documents/AppNotes/AN_108_Command_Processor_for_MPSSE_and_MCU_Host_Bus_Emulation_Modes.pdf]AN_108 Command Processor For MPSSE and MCU Host Bus Emulation Modes[/url] provides the necessary information.

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

General Discussion / Re: FT4222H I2C Master Reliability Issue
« on: February 10, 2021, 04:30:43 PM »
Hello,

Please see the following documents for all available configurable parameters:

FT4222H Hi-Speed Quad SPI/I2C IC Data Sheet

User Guide for LibFT4222

Also check is that you have added 1K pull up resistors to SCL and SDA.
The typical value is 1K.
Our hardware engineer suggest you can adjust it from 1K to 10K ohm.
There is some useful information here:

https://www.i2c-bus.org/i2c-primer/how-i2c-hardware-works/


Maybe there are other FTDI Community users who have had a similar problem and can help you further.

Hello,

Thank you for your question, would it be possible to see the section of code you are using to configure the device?

Discussion - Hardware / Re: Force FT4232H to Full-Speed (12MBit)
« on: February 10, 2021, 02:41:40 PM »
Hello,

Does the device enumerate as Full-Speed when you are using this 6m long cable? Are you seeing stability issues?

Yes, attaching the device to a USB hub which only supports USB Full-Speed would force the device to enumerate as a Full-Speed peripheral.

Discussion - Software / Re: Programming Altera Cylone II using FT232H
« on: February 04, 2021, 03:46:37 PM »
Hello,

I would suggest that you will need to contact Altera to determine support for 3rd party programmers with their products.
If you are trying to clone FPGA programmers that’s not something we can support.

Hello,

We are actively working with R&D to review FPGA timing.

Our IC designer has confirmed that the timing we are using in our demo application is a known good reference:

You can also contact your local support team via email as it seems you have already been in contact before:

Hello,

Unfortunately we don't provide support for xc3sprog, or impact/Quartus tools.

You can find the link below for support with this tool:

Hello,


Yes that is correct, they can be programmed to pull low during USB suspend.
Unfortunately however they cannot be programmed to pull low when neither RD or WR are asserted.

Discussion - Hardware / Re: UM245R baud rate
« on: January 20, 2021, 12:41:26 PM »
Hello,

Thank you for the update, I'm glad it is working at lower baud rates now.
As mentioned the baud rate setting shouldn't have any affect on the FIFO interface, but if this issue reappears please let us know so we can investigate further.

Best Regards,

Hello,

Yes that is correct when used in Input Mode, the input pins are pulled to VCCIO via internal 200kΩ resistors, so they will gently pull high unless driven by some external logic. These pins can be programmed to gently pull low during USB suspend (PWREN# = “1”) by setting an option in the internal EEPROM. But unfortunately you cannot disable the pull up entirely.

Hello,

This setting does in fact alter the USB descriptors presented to the USB host on enumeration, altering the host that the device is either Bus or Self powered. The USB spec requires that a device correctly identify itself to the USB host, so please ensure you have selected the correct setting for your configuration.

Forgetting to update the setting to reflect if you are using a bus powered or self powered design may result in enumeration issues for the device.

FTDI Community
