Hello, I bought a ttl to rs 485 converter to be able to read and write over arduino unoda rs 485, but I can't read, there are useless resources, can someone help, if there is a code that I can read and print data at least in the modbus pool about the connections and sample codes to be made, the room will be useful for me
I moved your topic to an appropriate forum category @murat913.
In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.

Q1: What have you tried so far?

Q3: What doesn't work? Post the error message or describe what happens currently and what you would expect to get instead.
Q4: Which device do you want to read from? --> Link to the datasheet/description of modbus registers of that device.
Q5: What Microcontroller are you using? --> Link to it
Q6: How does your schematic look like? Post a schematic and real pictures of your setup so we can see each module/wire/connection.
