TINA-Treiber Define für W5500 unklar

Hi Merlin,
I know. W5500 is the better chip.

Der ENC ist ja auch OK ABER der macht alles in Software d.h anständige CPU Last, was im Multitasking nicht gerade schön ist.

Die Wiznet machen fast alles selbst in HW, da bleibt viel mehr Zeit übrig für andere Aufgaben.
Zumal du beim W5500 dann 8 Sockets hast.

Da kannst du das ganze Dorf anpingen.

To oversimplify it, think of the W5500 chip as a telephone exchange. When you contact (or try to contact) an address you 'dial' a number (IP address) via an arbitrary line (socket) and all replies from that address are martialled to that line (socket). This can be (in processor terms) some time later, so while you are waiting for a reply you can also try to contact another IP address, but you need to use a different line (socket) because the first one is busy waiting for a reply. That means that you can be talking to up to 8 devices at once. Once your first conversation is finished you can hang up (release the socket) and the line (socket) is then available to contact another address.

Sockets can be used for other purposes too (like DHCP for instance) but, as I said, the description is an oversimplification.

D.h. wenn ich z.B. DHCP (da die IP evtl. erneuert werden muß) und einen Ping nutze, brauch ich 2 Sockets?

Gruss
