Circuit Diagram?

[nerawn]

Hello, first of all, I am Emirhan. I want to learn about this subject, but I couldn't learn much because it is old. Do you have a circuit diagram suitable for this code? I tried the circuit in libmbus but I couldn't get it to work. 😊

Hello Emirhan,
this is just a library to decode M-Bus, so there is no hardware assigned to connect.

You need only connect RX/TX to a M-Bus Master.

There is all you need, including .bin, wiring and links to proper working masters.
