Re: MIO Inputs either 0 or 10700 with 2-10v sensors (Converted)

Yes, the other inputs are not affected by readings from one sensor. Could you please sketch your schematic / wiring so we can get a better understanding of your setup? Thanks!

Re: Connect S with Buster not starting up after image written

Answer is simple: the 2021image was released even before the cm4s (which is the compute module in connect S) was invented. Thus the software cannot support this module. Support was added later. See the release notes, which state what devices are supported for a particular image. Nevertheless I reall...

Re: ifconfig shows wrong ipadress

Side note: ifconfig is a deprecated Linux tool since some years. The ip command is its even more powerful r...

Re: DS18B20 Temperatur Fühler

Hi,

du brauchst einen 1Wire Buskoppler den du z.B. per USB anschließen kannst. Auf die Schnelle habe ich die Produkte von esera gefunden, die es auch für die Hutschiene gibt:

Re: PT100 wiring on Compact

Hi

The RevPi Compact does only support 2 wire PT100 RTD, which must be connected to an input and it's 0V pendant. If the sensor is only available as 3 or 4 wire variant you could use an external temperature temperature transducer (converts the rtd to 0-10 V / 4-20mA)
