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.

Discussion - Software / Re: How do I configure FT232H device for I2C interface using FT_PROG
« on: October 23, 2020, 04:43:57 pm »
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,

General Discussion / Re: 1 USB to 3 UART using FT4232H
« 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.

Discussion - Drivers / Re: D3XX: FT_Create() fails with FT_DEVICE_NOT_FOUND in Debian Buster but not Ubuntu
« on: October 09, 2020, 04:35:25 pm »
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.

« on: October 05, 2020, 04:40:19 pm »
Hello,

We will need some additional information in order to help you on this issue:

1.            What is the winbond spi flash model number?
2.            What is the operating IO mode (single/dual/quad)?
3.            Can you request provide your source code?

Please send us an email with this information:

Discussion - Hardware / Re: FT602: How does individual WR_N transactions becomes 1 bulk packet?
« on: September 29, 2020, 03:12:33 pm »
Hello,

It can tell the end of the data by the BE (byte enable) signals. The 0x55 is an arbitrary value and is not actually accepted into the FIFO and so the value is not important.

The bus master asserts the signal for the valid bytes in a word strobe. Normally, all 4 bytes should be valid in a bus transaction except in the last word strobe when the data transaction length is not aligned at a word boundary. When BE[3:0]=0001 the FT602 knows that it is the end of data. The FT602 will also then see the header of the next frame and knows that the last frame has ended.

General Discussion / Re: FT230X Flow Control
« on: September 23, 2020, 04:40:29 pm »
Hello,

Flow control is handled by the application program.

For example, with terminal programs like PuTTY or Tera Term there are settings available in the application that allow you to select the type of flow control. These typically use the VCP drivers.

If you wanted to use the D2XX drivers that would involve creating your own application program that would allow you to configure flow control. You can take a look at some software examples here:

https://www.ftdichip.com/Support/SoftwareExamples/CodeExamples.htm

TN_153 Instructions on Including the D2XX Driver in a Visual Studio Express 2013 Project is also useful.

There is no handshaking prior to configuration in software.
