Phidget or SIOC

Hi everyone!

I am sure this is a topic that is very redundant, but I need your input! I have five analog gauge that I need to recreate for my sim. I am currently playing with the servo feature of FS2Phidget. I got the compass working with FS2Phidget test, but I got issues with the RPM 1 & 2, airspeed, Altimeter (I think I got that), HSI...no idea.

For the annouciator lights, I need: Rotor RPM high or low, Bat Temp, Bat discharge (low V.), Transmission oil pressure & Auto Pilot Auto trim.

Can anyone help me with Phidget?

For those of you that use SIOC, would does functions be easier done with SIOC?

Thank you everyone for you time!
