>> > ADC0 and ADC1 are reported in the standard telemetry string.
I think this is NOT correct. The standard telemtry string of an OT2M looks like this: T# internalTemp,Voltage,ADC0,COUNT,HDOP, 0,0,0,0,0,0,JUMPER,PROFILE Unfortunately it only reports one ADC line and COUNTER from the M08 connector. There should be a file in the files/picture section describing details. For weather stations and telemetry applications it would be much better to have more and selectable analogue ADC-I/O lines available. However, you could use an OT1+ or OT1SMT... vy 73 de Mike oe3mzc ----- Original Message ----- From: "Scott Miller" <[email protected]> To: <[email protected]> Sent: Monday, November 09, 2009 6:40 AM Subject: Re: [tracker2] Re: A/D inputs > Not all of them are general purpose I/O lines.
