Hello all!
I'm having a (seemingly peculiar) error when deploying some code to my Netduino Mini. I just received the Mini, dumped a simple Blink program on it to verify it works, and then tried to dump the following code onto the Mini.
The error I am getting is "An unhandled exception of type 'System.ArgumentException' occurred in Microsoft.SPOT.Hardware.dll" Occuring on Line:33
I have tried changing the Input pin, but same issue. Currently running .NETMF 4.1 as my current program framework. Any ideas?
