lwIP_enc28j60 and ESP8266 required PINs

[rescalda]

Hello, in all the images/tutorials/examples I see on the web, in addition to the 4 SPI pins, there is connection of the RST and INT pins to ESP 4 and 5. I don't see any reference at those pins in the source code, with a scope I see no activity on the pins, I can disconnect them and the sketch works fine.

At this point, I would like a confirmation there are no side-effects connecting those pins to something else (very useful indeed!). In any case, I think that a note on the pins would be useful in the readme file.

the EthernetENC library (and I guess the lwIP_enc28j60 too) does a software reset at initialization. wiring reset pins together does a hardware reset of the enc28j60 when the MCU is reset with the reset pin or watchdog.
the EthernetENC doesn't use the INT pin. it polls the enc28j60 for new data. the low level code is based on code created by Atmel so I guess lwIP_enc28j60 uses the same approach.
