DS18S20 One Wire Tutorial

[Andreas]

Hello

as my first script with the Controllino MAXI I try the OneWire example from the build in tutorials. On port SDA (pin 20) it works fine as describred.

https://www.controllino.com/knowledge-base/1-wire-temperature-sensor-ds18b20/

In the example is explained that is working on other ports, too. D0 is pin 2, or A0 is pin 54, but I get no signal from the DS18S20. What is to do?

Best regards

Andreas

Hello Andreas,

do you have any progress so far?

Have you properly changed the pin number also in the sketch?

OneWire ds(20); // on pin 20 (a 4.7K resistor is necessary)

Thanks,

Lukas
