Re: AIO: Connecting output terminals V+ and I+ with a shunt

Hi AleksejsTarasovs, if you operate the AIO module within the values specified in the AIO module data sheet , the circuit is irrelevant. However, this type of alternating configuration during operation is not intended. Specifically, the point is that you either output a voltage or a current at analo...

Re: Module is NOT present, data is NOT present

Dear ejsol, okay, I didn't really understand that means the communication doesn't work with this image? Or can you try it with this freshly released image? RevPi Bookworm 64-bit (10/2024) (ID: 9162) Can you please check whether the firmware of the IO modules can be updated? This works quite simply w...

Was passiert denn jetzt, das nicht funktioniert? Ich meine, die Flask Applikation besteht aus einer Web-Applikation, oder? Es weird ein HTTP Request gestellt, diesem folgt eine HTTP-Response request, oder? Ich denke, hier muss kein Troubleshooting gemacht werden. Interessant ist doch die Frage, was ...
