FTDI where are you?

works fine from here..

-jg

Thanks for checking that Jim, but it's still not working for me. Every other site I go to is.

Strange, I didn't think the Internet was discriminatory :)

Thomas

Hmmmm... I just sent them an order 30 mins ago, and I see the domain as down also.

I'm in Australia, where are you Thomas?

Best I send the message via one of their satellite domains.

I'm in western Canada.

How do you get in through one of their satellite domains?

Thomas

for email only.

I know sales people in Easysync, and they are in the same building (in Scotland), so they can duck any emails across to them, as they have done in the past. :-)

FTDI, Easysync, USB Instruments, Vinculum, all the same family business.

Same problems with wwe.ftdichip.com here in Oregon. I was able to get to an online store by clicking links at

I suspect that FTDI is in the middle of a reorganization of their online presence, and the DNS updates are not yet complete.

Mark Borgerson

No response from here (UK). As someone else said, DNS propagation, maybe... give it 24hrs.

Steve

well...... only one in 4 of those home pages I just mentioned is working

I briefly got on to their home page this morning. Super slow, barely functioning.

While I wait... does anyone have any experience with their FT2232D chip? We are looking to use it to do some FIFO dumps and some bit banging. How are the API's to deal with?

Thomas

At the base level not too bad, use the special function API's such as SPI and I2C at your own peril, the calling parameter list is a nightmare (14 plus agruments with not a structure or array in sight).

If you want some examples, based on a kernel I used for a customer who insisted on VB6 look at

Note that today there may be a DNS changeover delay, due to DSL supplier change beyond my control.

I did note that their driver can cause problems probably due to what version of Windows and Service PAck and hardware on your motherboard. This however is part of the nightmare of USB and the many parts beyond your control.

Especially if the USB hardware vendor insists that all updates are done via Windows Update, and Windows Update insists for that type of laptop or tablet or whatever there is no upgrade beyond SP1.

             For those web sites you hate

all up again. email is up, but may take a while to sort itself out.

I was speaking with Fred Dart (owner) and he said they were with a UK ISP who is extremely laid back when it comes to support.

I suggested he should shift providers as soon as possible. I went through a similar thing back in April last year.

The 2232 is good in as far as it goes, which is SPI, I2C and JTAG. Anything other than that, beware. Although the data sheet includes the sentence, "The MPSSE interface is designed to be flexible so that it can be configured to allow any synchronous serial protocol (industry standard or proprietary) to be interfaced ...", in point of fact it is not flexible enough to accommodate many of the protocols used for serial devices like ADCs. In particular, any protocol that requires the clock to be high in the idle state, with data changing on the falling edge, has to be manually bit- banged, which is very slow indeed given the 1ms USB time frame.

Paul Burke

I also find the 2232 good with it's 245 FIFO. Channel A serves me to jtag program the jtag chain consisting of an AT90CAN128, XFC04 and a XC3S500E. In channel B I dump data from the FPGA to a PC with quite high rate.

I don't use any API. The FTDI is programmed via the EEPROM to act as FIFO on channel B, and on the PC side, I open /dev/ttyUSB1 (or 3) to see the data.

For programming Xilinx parts, look at sourceforge for xc3sprogs. There are my patches pending to make it work faster and more general with the FT2232.

Bye

Name and shame!

Our company ditched FutureNet last year because they bungled our internet connection (although the website was still functioning) and spent two weeks blaming everybody else without ever managing to fix it.

Not from NY, USA.

Thanks Paul, That's the kind of info a person needs to know before drawing up a schematic. It's easy to throw in an inverter if needed. Are you using the

2232C or 2232D version?

BTW...The

website is still not working for me. Tough way to sell product...geez!

Thomas

Just spoke to Fred, who is on a family holiday in Prague.

They (ISP) have switched him to a new server but they have to upload all web sites again and set up all the email accounts ** again **.

There is a page notice at

new web site messages at:

Fred suggests you use the fax number for urgent correspondence.

Reminds me of Affordablehost.com when they stuffed me around in April

2006, when I was on a family holiday. Went off line for a week. I shifted everything to a new company in 24 hours.

2232D. Watch out with inverters... check that the connected device doesn't throw a wobbly if the clock is left in the "wrong" state. I think the problem is more to do with outputting the first bit without a clock edge.

British web sites... the hosts haven't cottoned on that they are more than a toy.

Paul Burke

The FTDI FT2232 could be fine enough for JTAG interface (max 6 MHz TCK Frequency). The Amontec JTAGkey is based on this FTDI device.

The JTAGkey performances are as (on Linux and Windows):

- downloading Xilinx Virtex, 7.9 Mbits bitstream at 2.8 secondes (via SVF file)

- Erasing / downloading / checking Xilinx Coolrunner XCR3128 at 0.7 secondes (via SVF file)

Note : the 2.9secondes includes ~500 ms to parse the SVF files

We are working on some examples codes as including .bit file support for Xilinx Spartan 3 and other Altera / Lattice devices.

Our SVF Player comes with sources from the

page.
