Getting data sent from ethernet

For the str9 comstick, does anyone know how to get the data that is sent to the ethernet port.

It is to read from Pin 0.2 to 0.5 which is the MII_RXD0,

PHY Rx data?

Thank you for any replies.

Lazycat.

Hi Lazycat

The RXD lines of the MII interface are used by the Ethernet controller to receive the data from the external PHY device. The MII interface must be configured to operate in this mode and the interneal Ethernet controller must be configured to automatically receive the data and save it to internal RAM. To do this its buffer descriptors must be correctly programmed.

The SW doesn't use the MII data interface except for the serial lines to configure the PHY and read its status.

Hi

Yes, this is correct, but it is up to you to first configure the Ethernet controller to correctly use the buffer descriptors.

PS. Check out the following page for some demo code for the STR91 - with FTP, Web Server, HTTP etc. There is one for the ST STR91 dongle, which may run also on the COM stick(?). There is also a demo inline at
