Hi,

 

I have recently started to work with ARM. I have read a bit about it but, unfortunately, I have not ever been successful in implementing my code in practice.  When I connect my board to the USB port of my PC an error message says: “USB device is not recognized.”

Have you ever faced this problem? Do you know how it can be solved?

It would be so grateful if you could guide me in this regard.

 

Thank you veryyy much in advance,

 

Hossein Amooie

@Hossein Welcome to Stellarisiti.

Which code did you try? Did you load up the drivers?

Yes, need more info.  Are you hooking to the programming or device port.  Are you having issues programming the device or setting up the board as a USB device?  I've been working with @lawrence_jeff on a USB device implementation and haven't had any major stumbling blocks with getting the board to show up as a device.  Give us a more detailed explanation of what exactly the issue you are having is (code examples are helpful if appropriate), and we should be able to get you up and running :)

Download the Stellaris Launchpad Workbook from 

 

http://software-dl.t...PadWorkbook.pdf

 

and go through the first few pages. It has a detailed explanation on how to setup the device and how to set up CCS etc.
