i have a few sensors that i need to connect to a controllino Maxi Pure
For some reason, i can't get it to work. The example on the Controllino webpage is
using a Maxi Automation but according to the page any Controllino should be good.
I have a 4.7k resistor between 5V and the signal line.
I can read the address and temperature of any sensor with a normal Arduino Uno,
but no response comes from the controllino. I can't tell why.
I have connected it to several inputs, none of them seems to be working
D0 -> Pin 2 ,
D1 -> Pin 3 ,
A0 -> Pin A0
IN0 -> Pin 18
No that is really not the issue. The Controllino does have 5V onboard. I'm just not sure if i can use the screw terminals D0-D11 to use as arduino inputs. I start to doubt it. Very poorly documented.
I'm not familiar with it or its inner workings, but I wonder if the issue is that the D0-D11 screw terminals are outputs. There's likely to be some electronics in the way that is configured for those terminals to be purely outputs.
With a DS18B20, I think you need a pin that can be both an input and an output (i.e bidirectional). I would hazard a guess that you may be able to use one of the digital i/o pins on the X1 or X2 connector as the notes suggest that these are routed directly to the internal micro via a series resistor of some undisclosed value.
