USB CDC

 USB CDC

Hello,

Are there any examples availabe for creating a virtual com port via the USB port on the STR7EVAL board?

I would like to be able to transmit data from hyper terminal to my STR7EVAL board. I am very clueless about how to go about this. So if anyone could give me some advice or an example or a link to website with info, it would be greatly appreciated!

Thanks,
Eric

I forgot to mention: I am using Keil's uVision3 Realview MDK tools for ARM based MCU's along with the STR7EVAL board.

You don't want to use RS232 UART? Cause that's the way to go if you would like to be able to send data from Hyperterminal to your evaluation board.

Sorry do not know any examples for the keil tools.
The only example i know of is written by me for the Anglia toolchain (gcc), it is available on the stmcu site.

Rene, with the usb cdc class you can still use hyperterminal as it a virtual comm port.

STMCU is a pretty big website. I tried looking manually as well as searching with a variety of search terms but couldn't find you or your USB CDC class there. Can you provide a link to it?

Thanks,
Dave.

Thanks for the replies. Dave, I found sjo's code on the ST website: http://mcu.st.com/mcu/modules.php?mop=modload&name=Splatt_Forums&file=viewtopic&topic=3253&forum=17&start=0

(under forms -> arm 7 str7 -> USB demos for Raisonance/GNUARM) -- it is towards the top

Thanks,
Eric

Dave,

If you manage to get a working USB CDC program in uVision, could you let me know?

Thanks,
Eric
