Usb cdc

By default the CDC is 9600 right? So would I have to alter the properties for the virtual COM device in Windows to alter this? Ideally I’d want something like 115200 or more?

Also how do I detect if I’m actualluy plugged into a PC? At the moment I’m just sending data to the CDC regardless?

You should give a look at the online doc

and especially this page : http://ghielectronics.com/downloads/NETMF/Library%20Documentation/html/93fcfa03-228b-cbe4-e8a5-9a7a8f36cdf0.htm

You can see this code:

// Check if connected to PC
                if (USBClientController.GetState() != USBClientController.State.Running)
                {
                    Debug.Print("Waiting to connect to PC...");
                }
                else
                {
                    cdc.Write(bytes, 0, bytes.Length);
                }

Edit: URLs with the % sign seem to not display correctly :think: Simply copy/paste the whole link in your browser.

Wow you know I totally overlooked that even though I passed it several times :confused:

Baudrate does not matter. You are communicating over USB.

Sometimes, the most obvious things become invisible because we look too much at them and we don’t pay any more attention to them :wink:

Bec: Yeh :confused:

Mike: Ahh didn’t realise just confusing all these intermixed things and it being a virtual COM port :frowning:
