Hi,

It also looks like there is a design challenge using a WIZNet part running on Circuit Cellar. There are samples being given away, and a prize for the winner :

Hello Heiko,

thanks for your interrest and sorry I did not answer more early, but our Team was on embedded world and on AMPER exhibition. Now we are all back and I like to advice in parallel to take a look into the WIZnet Wiki "the living Datasheet" and the Forum for more detailed tech. support by all global WIZnet members. Wiki: http://wizwiki.net/wiki Forum: http://wizwiki.net/forum

Anyway the WIZ550io Module and the W5500 chip is best for the mbed platform to add high performance Internet connection. You find our Products also at mbed components -> Ethernet : https://mbed.org/components/cat/ethernet/

best regards, Joachim

we just recently posted an example where we interfaced the Arduino Ethernet Shield with a Nordic Semiconductor nRF51-DK.

there might be some lessons to be learnt from our experience on this.

Hi Martin,

I post the W5500 driver and you can use it with WIZ550io. https://mbed.org/users/jbkim/code/W5500_Driver/ I'm porting it to existing mbed Ethernet stack.

Thanks, Jinbuhm Kim

Hi Heiko, could you point me to the library you used to get this working, possibly with a link.

I've got a stand-alone Wiz5100 board, the Wiz812MJ and I'd like to try to get it working with the L152RE Nucleo.

Many thanks,

Hello,

from top of my head, look for wiznet modules, search for w5500 or w5200, there are libraries. I have seen it used with KL25Z. I have one at home but not yet tested.
