RS485 Enable Pin - RS485 Max

[lugg8]

Hey,
I am using the HW-097 Converter and I am wondering how to modify the code to get the RS485 communication working.
somewhere I must add the Enabler PIN (5) to the code.
may you assist here?

Many thanks in advance.

I'm working on a rewrite of this code with the modbus implementation from this repository. https://github.com/kfroeschl/HCPBridgeHomeAssistant/tree/rewrite Kfroeschl use ModbusRTU where you can submit your enabler pin in the setup. Will publish an experimental branch im my repository as soon it's ready.

Hey @lugg8 I pushed an experimental build here. https://github.com/14yannick/HCPBridgeMqtt/tree/development
There you can enter your enabler pin /src/hoermann.h line 216 put mb.begin(&RS485, 5);
Untested and without warranty.
Best regards
