Hi chef,

Try erasing your current app. Grab a copy of Netduino Update (from the 4.3 beta thread, in the beta forum). Instead of reflashing your board, click on board settings > tools > erase current app.

Does that get you back up and running?

What version of NETMF are you targeting? What version of this DLL are you adding?

BTW the only effective differences between the built-in NETMF AnalogInput and the SecretLabs AnalogInput is that you use ReadRaw() to get the full range with the former and you use Read() with the latter...and the scaling/offset works a bit different. For most applications we just use the newer built-in NETMF classes.
