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

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


USB Host

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


USB? Ethernet? Bluetooth?

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...


How to design a bidirectional bus?

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). My system has several subsystems which have to have bidirectional data flow with host. There are two things which are not clear for me and I would be glad to get an advice on these. 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...

I'm converting an application from Windows console to Linux, and the changeover has gone remarkably easily (considering that I know very little about Linux), until now. No problem installing GCC, KDevelop, FTDI USB drivers, remarkably few changes to recompile the code... but printf fails after about half-a-dozen calls. A float value prints as "nan"- not a number I asume, rather than w...

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

I was trying to build a datalogger which writes data into a USB thumb drive, are there any 8bit micros out there that can directly write to a FAT formatted thumbdrive? The only other chip I know of is the VNC1L from ftdi, which is great except that I can't write custom firmware for it and will need yet another micro to control it. (also a micro that has a free compiler toolchain would b...

Win8 does notice it was plugged in (it beeps) but nothing new (that I can see) appears under Control Panel / Devices. I would expect a COM port with a Hayes compatible modem behind it. That is what their older models do. The old 7100 is a straight RS232 Hayes modem, but the XT is...

Hi, I don't know if there is a better group to ask about USB. I want to create a device that will communicate with a PC via USB. I prefer USB to RS232 because I plan to power the device from the USB supply.
