![]() If you know, please kindly share it here. Able to build the prototyping circuits matched with Arduino. Extends out all the control pins and power pins of Arduino. Comes with a power led and a D13 indicator. You can find it on w5500.cpp: void W5500Class::init(uint8_t ss_pin)īut please be aware if your Wiznet module is already flashed by software reset, you need to rewrite the MAC Address using Ethernet.begin(mac) (and it goes without saying, please comment #define WIZ550io_WITH_MACADDRESS on file Ethernet2.h before do Ethernet.begin(mac)).īut this solution came up with anoher question: Why we need to do software reset after all? I have comment it and still haven`t find any problem till today. The datasheet provides detailed information about the microcontrollers features, including its memory, I/O, and peripherals. Can be plugged into the MEGA 2560 control board. I peek into the Ethernet library and found out everytime we init the Wiznet module, we do software reset. So the conclusion is if you use software reset, the MAC Address value (and the other like IP, DNS, Gateway, etc) on the Common Register W5500 became zero.

Keyestudio W5500 is based on the microcontroller of Arduino Ethernet.We have integrated USB download, TF card slot and more functions on it, fully compatible. 54 digital input/output pins (of which 14 can be used as PWM outputs) 16 analog inputs.
