--[[
A simple Telemetry window monitor to show the poti's analog value 
and digital switch digital values in a Telemetry window. 
This might be helpful, when the logfile is played just to get an idea what is going on.

When other inputs should be display, just change the <ch> or <sw> value according to 
the specification and the desired Poti or Switch or ...
