I have a BS50 loaned to me for evaluation, but I have no disk. The manual is not clear about whether a special driver is needed or if it uses standard divers from FTDI. I sent an email over 24 hours ago and no response. I know they are in Australia so it can take a while to get a reply, but I would have expected something by now. They don't say if the "test drive" download is the fully f...

If I want to devel a USB HID device, I have to buy an USB Vendor ID or there is an alternative? I've seen that with FTDI chip I don't have to set that ID, as I suppose they use their own Vendor ID.

Hello All, I have two questions. They might be very basic and foolish :) I use In circuit emulators and debuggers regularly. One of the constant problems I face is when the MS WindowsXP fails to recongise the device. Sometimes it is the FTDI USB chip driver which goes haywire or sometimes its something else. It shows the name of the device in device manage Normally I circumvent this p...

Has anyone here ever had a response to a support query for the Vinculum VNC1L or anything else for that matter? I don't get as much as an automated ack. I thought the purpose of the chip was to make life easier when implementing USB host function but this is getting to be no joking matter. Peter

Hello All, The VNC1L is the host interface to the USB flash drive made by FTDI. I couldn't find any data on its performance. However there are the rumors that it is only about 300kbytes/sec. Based on your experience, what would be the realistic speed of the file read/write operations using this chip? Vladimir Vassilevsky DSP and Mixed Signal Consultant www.abvolt.com

Just spent an hour googling I'm trying to find a reasonable BL for the enduser, preferably using USB/FTDI or the silicon labs thingy/equivalent. Just to update their AVR, nothing special, apart from "simple" and probably a lot of Mac users Using GCC Winavr, Ponyprog and atmel Studio4 I'm just sort of (still) learning the AVR, so any suggestions, plus /minus points would be

What's the least painful way to implement simple (as in a strictly limited set of connecting devices) USB Host support on a C8051-based design? USB Peripheral mode is easily handled with something like FTDI's chips. Atmel's AT43USB380 looks interesting. However, not sure if their API's support the 8051. Thanks, -Martin

To date, most of my headless embedded development has been either entirely stand-alone, or has communicated with the outside world via serial. Serial is kinda old, and getting clunky. Yes, you can use a USB to serial converter from FTDI or whoever, but then you have a USB connection that needs to have a baud rate specified, which is just strange. On the other hand, USB and Bluetooth b...

Hello, I want to design an FPGA-based system which is controlled by PC host through USB-parallel interface (I use UM245R module from FTDI).

First, I do not understand how to organise communication through paralle...

I sent this message to FTDI, but have not received a reply. Maybe someone here can answer this question. I have built a board using the FT2232C where I am using the MPSSE mode for JTAG. The FT2232C is being interfaced to an LPC2119. Specifically I am using the bit commands 0x4E and 0x6E to send and receive data from a JTAG interface. I am noticing that when I use the 6E command to read dat...

Hello, I'm new in this group, and I hope this is the right one to place my question. I am trying to connect a tilt sensor to a pc. The sensor device (Analog Devices' ADIS16201) is accessable via spi. Unfotunately, I'm not very conversant with programming Micros not even with programming serial communication. But since SPI is such a simple protocol I tried it using FTDI's FT2232C. That did no...

Hi, Can anyone advise me if I can use my Olimex USB MAXQ2000 JTAG programmer to program ARM microcontrollers?. The 10 pin connector would have to have a 20 pin adapter made to match up the JTAG signals correctly. Internally it contains a FTDI FT232BM, a LCX244 and a DS89C430 micro if that's any help. tia Mark

Earlier I was able to interface with a ADC (ADS7871) using the SPI interface provided by FTDI. It was really a struggle but that it is working quite good now. Now I am trying to interface with a DAC which is AD5420AREZ from Analog Devices ( http://www.analog.com/static/imported-files/data_sheets/AD5410_5420.pdf ). The pin assignments are as follows: ADBUS0 -> SK = Serial Clock - Connect to A
