Hi,

On the old Netburner Yahoo mailing list, "frunchy" asked if anyone had added a second ethernet port to the MOD5234. Paul Breed responded that there was an app note in the works, but it hadn't been published yet. That was in November of 2007. Has the app note been published yet? Will will that design work with the MOD5282? Let me know.

Thanks,

Dan

Dan:

Do you want to add a SECOND serial port or an SPI port?

A second port is trivial, all you need to do is add a level shifter, MAX202, that sort of chip, to the existing U1Rx and U1Tx lines at MOD interface

If you want to add a third port, there are re-assignable pins for that, too.

If you want to add a 4th port using SPI or the QSPI or whatever, that can be done and I have done it before with other NB boards. IT will also work with the MOD- boards. You would use one of the serial port UARTS. I really like the SPI ifc. SC16IS762IBS dual uart. Soldering it is particularly exciting.

We have code and example of using the microchip SPI/10 base t Ethernet chip.
Submit a support request and we can send you that.
(If you want to do a parallel inteface the code is a good starting example )
