I have a RevPi Core 3 connected with a DIO (on right side of the RevPi Core 3) - the 3 LEDs on the DIO are green.
This is a good start, you have done well so far.
I configured (see screenshot below) the setup and for the output port 1 I did set the value to 1:
Why is the output not switched to HIGH when I set the BOOL to 1?
You have to use "piTest -w O_1,1"
How come I see 16 outputs in PiCtory and only have 14 outputs
Well, you are right, it is a thing that should be cleaned up.
Is there a log files where I can seen the DIO state?
No you can use the RevPiCommander which is a great tool to work like a digital twin.
So far I am not able to set the outputs of the DIO. Suggestions are appreciated
I hope that I could help you there is also a nice made with love video tutorial available
