Dev Bugfix: Analog channel 0 overwrites digital channel 0: The search for the next analog channel was stopped in case the iteration is reset to zero => channel 0 was always sampled, even if no connected sensor was detected. This caused the values of a connected digital sensor to be overwritten. The search loop will now (again) iterate till it finds a new sensor or till the index reachs the active sensor index.
