net-Shield | Simple Anti-DDoS solution | Hacking library

I want to use my Arduino Mega (with a sensor shield) and an ENC28J60 Ethernet module (directly connected to my PC) to send and receive UDP from a flight simulator (X-Plane 11, which is capable of sending UDP via the network).

The network module: http://www.ebay.de/itm/281353516180?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

I can't manage to write the received UDP data into the serial monitor however. I am not even sure I really do receive UDP.

The connection between Ethernet module and PC seems to be fine, as the green LED of the Ethernet module's I/O is permanently on, and the yellow one is blinking as soon as I start my flight sim and send UDP from there.

I have tried both, standard Ethernet cable and crossover.

I have have tried 2 ways of connecting the ENC28J60 Ethernet module to the Arduino Mega sensor shield, according to 2 different guides.

1. Standard wiring for the Arduino Uno

   • Enc28j60 SO to Arduino pin 12
   • Enc28j60 SI to Arduino pin 11
   • Enc28j60 SCK to Arduino pin 13
   • Enc28j60 CS to Arduino pin 10
   • Enc28j60 VCC to Arduino 3V3 pin
   • Enc28j60 GND to Arduino Gnd pin

1. Recommended wiring for the Arduino Mega

   https://en.code-bude.net/2013/06/22/how-to-use-enc28j60-ethernet-shield-with-arduino-mega-2560/

   • GND to GND
   • 3.3 to 3.3V
   • SO to Pin50
   • SI to Pin51
   • SCK to Pin52
   • CS to Pin53

I also tried several libs:

1. EtherCard: It is recommended to set the cs pin to 53 in the library files, which I did. Plus one should use this line of code in the sketch (which did not compile. Error is with the use of sizeof in combination with Ethernet::buffer)
