Improvment sensor Autodetection:
The sensor type optical has been introduce to enable the OSTC to completly switch of the external interface (voltage + ADC operation) The optical interface is handled via firmware. In addition some states have been added to reset the external power supply and to provide the ADC more time to do its conversation.
