it took me some time trying to find out why the pin I was choosing based on the Eagle Schematics (Codeplex) was doing nothing.
Codeplex has Hydra 1.0 but I received a Hydra 1.2 - all sockets where renamed.
Could you update the Design files / code for the Hydra on Codeplex?
My intention is to try to figure out how to build a firmware for the Hydra in GCC so I can write some interop code.
Best regards, mark
