Hi, one of the simplest solutions is to connect the nRE and DE lines together and control their TX signal with a small inverter with an RC filter at the input, which creates a short delay – thanks to this, the transceiver switches itself to transmit and receive mode (so-called auto-direction) and you no longer need to manually manage RE/DE.
