Hi Rastan !

I don't know your goal but why dont you make it easy for yourself and use a USB to serial converter ?

I done that and if you take off the insulation on the usb cable you can take 5 volt from the usb port and feed your application with that.

Then you map the converter as COM8 for ex. and it works like the rs232 communikation you already done.

yeah i did think of that, but i thought that the serial to usb chips were less functionable than others. in what way im not quite sure. it seems like they are made to do one thing and that only. for instance it says that it can transfer data at full usb 2.0 rate, which is 480MB/s, but surely isnt that then limited by the USART speed??? at 115200 baud??

anyway, for now, i do think that the serial to USB chips are a good idea, so i already know that FTDI do them, but does anyone else know of any other company that does the same sort of thing?? (assuming its available to the UK)

thanks,

phil

rastan,

we would be really interrested in your PIC solution
(hardware & software)
that deals with data @ 480Mb/s

[rastan]

ok, no need to to be sarcastic. i just thought that it would be possible using sepecific hardware.

still the question remains. does anyone else know of any other simple USB to 'something' chips to use??

cheers, phil

FTDI or PROLIFIC is what you should look at.

Depends of course what you want to do with the USB Interface and the IO, but this may interest you : http://www.delcom-eng.com/products_USBIO.asp#USBIO

It's a simple USB Interface Chip that has a number of IO lines. It comes with its own DLL and example code etc.

This Chip does exactly what i want, however, probably like you, i want to perform the task using a PIC and not a third party chip.

Hope its of use anyway.
