Controllino does not receive the data RS485

[Lukas]

Hello,

please, check our latest example code.

You do not need to manipulate with the direction control signals via registers. We already provide API for that.

I am not sure about the M-duino RS485 implementation, but it is always important to wait until the transmission is (physically) finished and then switch to reception.

Best regards,

Hello,

I copied the code but without success.

I do this because the CONTROLLINO library does not work, I have this error message:

#error Please, select one of the CONTROLLINO variants in Tools->Board

For now the M-Duino is only sending data so there should be no problem

Waiting for your reply,

Ok, it’s good the CONTROLLINO library working.

But still the same problem, I do not receive anything with the controllino in RS485

Waiting for your reply,

Do you have the same baudrate at both sides? Have you interconnected also the grounds?

May I ask you to share the latest source codes at both sides and also a photo of the wiring?

Thanks!
