Hi All,

I am trying to make the Teensy++ 2.0 communicate with WIZ820io module, but with no success. When I compile and upload the WebServer example, the following message appears in the console window "server is at 0.0.0.0". Moreover, when I try to see through the w5100.cpp file which chip is selected, the response I get is that no chip was found.

Any ideas? I am using Arduino IDE 1.6.5 and Teensyduino 1.26. I used the following wiring to connect the Teensy++ 2.0 with the WIZ820io module:

9 ->RESET
10 -> SS
11 -> MOSI
12 -> MISO
13 -> SCLK

Extrenal 3.3V Power Supply -> VIN33,VIN33
GND -> GND,GND,GND

Thanks in advance!

Those are the connections for Teensy 3.x & LC.

For Teensy++ 2.0, try this:

9 ->RESET
20 -> SS
22 -> MOSI
23 -> MISO
21 -> SCLK
