General

Question

There is no article about how the W5500 in general works respectively how in general it must be used. I think now it is in this way (under considering the SPI Frame Format) General initialisation This must be done to write parameters like the ip-Adress etc. to register 0 (Address Phase 0) 2.) Load the data to send into the TX-Buffer of one of the sockets (Default 2KByte place for data). 3.) Send the Send command to the command-register (is there any). 4.) Find out if all data has be sent. (How?) Is that right?

FranzPeter: There is no article about how the W5500 in general works respectively how in general it must be used. Franz-Peter, W5500 datasheet is really scarce of this information. I recommend you taking W5100 datasheet, it has very detailed overview how socket should be used. W5500 logically works the same way, having 8 sockets and different register layout. In W5100 datasheet you will need to pay special attention to: page 28 socket status register transition diagram; page 34 cyclic buffer usage; page 41 and further for how to program socket. I hope it helps.
