Wiznet W5100S

[Chubls]

Hi All,

I'm quite new to this so i'm probably doing something wrong, or putting this in the wrong place.

I currently have a RP2040 rigged up to a Wiznet Ethernet Hat for the Pico (Uses the W5100S Chip). So ive set the CS pin to 17 and all the numbers tally up correctly.

I've run the "HelloServer" example, the code compiles but i get the following;

Any help with what i'm doing wrong? or does this library not support the S model?

Thanks

I don't have that Wiznet Ethernet Hat for the Pico to test to know what's wrong, but from the connection, the 2 pins INTn and RSTn are connected directly to GPIO21 and GPIO20 and can cause issue to the firmware, if not pulled HIGH.

I suggest that you add to the beginning of the code something like to see if it's OK

#define PIN_RSTN      20
#define PIN_INTN      21

pinMode(PIN_RSTN, OUTPUT);
pinMode(PIN_INTN, INPUT_PULLUP);
 
digitalWrite(PIN_RSTN, LOW);
delay(1000);
digitalWrite(PIN_RSTN, HIGH);

If not, I have no idea untiI have the board to test and investigate. You can also post an issue on Wiznet website to ask for support,

Good Luck.

The data is wrong here WIZnet Ethernet HAT

Pin INTn is OUTPUT, not INPUT for W5100s
Pin RSTn is correctly INPUT for W5100s

Any Luck so far?

Hi,

I just bought and received one WIZnet Ethernet HAT and have changed the Ethernet_Generic library to provide preliminary support that W5100S HAT for both RP2040 arduino-pico and ArduinoCore-mbed cores.

Will release a new version with several days.
