I tried to put three gateway on the uC (which doesnt reply)
127.0.0.1
and None. ( I tought none would put a good default address...)
and the uC own ip address
and 255.255.255.255 (Broadcast)
I tried the following mask on the uC
255.255.255.0
and 255.255.255.255
Of course if I put my comp and the uC in the same subnet, the ping work...

So they are on different IP subnets? Then the packets must be routed
through a gateway. In your explanation, a gateway is never mentioned.
Choose your IP addresses from the same subnet to remove this
complication. Once you get it working, you can try different subnets.
