I have a Teensy 3.2 and a WIZ820io ethernet module.
When I connect them on a breadboard with jumper wires the combo works fine:
- initializes to the given ip address
- responds to pings
- correctly serves up a web page
When I connect them with the PJRC WIZ820_SD_ADAPTOR, it always initializes to ip address 0.0.0.0 and doesn't work.
I've tried different hardware instances of Teensy 3.2, WIZ820io and WIZ820_SD_ADAPTOR with the same result.
I've read the forum postings here on this subject but I still don't understand what's needed.
That fact that it works fine on the breadboard seems significant.
Thanks for any help!
