I can’t find any information on the issue, but looking at some issues that Netduino users have experienced, it seems to be down to there being no pulldown resistors at CPU level for the Panda?
I’m getting “An unhandled exception of type ‘System.ArgumentException’ occurred in Microsoft.SPOT.Hardware.dll”
on the line
Colms = new InputPort((Cpu.Pin)FEZ_Pin.Digital.Di21, true, Port.ResistorMode.PullDown);
Is it a case that I need to use my own pulldown resistors?
