Ethernet over USB

Hi Mohammad,

as far as I know it was never mentioned to have this (we're still waiting for the Mass Storage Class (MSC)).

P.S. When you need Ethernet connectivity in your application, have you ever thought about using Stellaris in favour of MSP430?

Hi aBUGSworstnightmare,

You are right when you said it was never mentioned to have EEM class; however, it is feasable especially when the rest of the USB stack (or most of it) is available with this family of device.

Do you have any idea what efforts will be requied to implement EEM class?

I will throw another question on top of the first one: in order to implement Ethernet in F55xx, TCP/IP stack will also be required once EEM is developed. Is something readily available for TCP/IP implementation? What type of efforts are we looking if one needs to be developed?

Thanks,

Hi,

Andreas Dannenberg has ported a TCP/IP stack to the MSP430 back in 2004; look at this application not (find the sources on the TI App Note pages) http://focus.ti.com/lit/an/slaa137a/slaa137a.pdf.

So far, there's only a CDC/HID stack available; I have no idea what is needed to implement EEM class.

Yes as aBUGSworstnightmare pointed out I’ve implemented  web server that runs HTTP and TCP/IP over Ethernet on the MSP430. It uses an external MAC/PHY.

However this project hasn’t been updated in a while but there are other TCP/IP over Ethernet stacks available that run on the same hardware. One excellent option is a stack is called uIP and was written by Adam Dunkel that seems quite popular:

Thanks and Regards,

Andreas,

Thanks for providing further information about TCP/IP implementation. I will look into Adam Dunkel's stack in hopes that it provides more functionality.

I have another question if you have access to details: Is there a USB EEM (Ethernet Emulation Model) stack available from anywhere to implement on MSP platform. We are using F5522.

Thanks again for your time and help.
