Re: rs485 driver #stm32

Hi Arsenii.
I have already used that with an external transceiver driving the RE/DE every time we would write to and disable it after that as a generic GPIO (output). We write the data using a regular UART driver. The RS485 part is performed by the transceiver. 

I hope it helps.
Best regards,
Rodrigo Peixoto.

Hello.
Is there any driver or may be some way to use rs485 on zephyr? May be someone used zephyr for rs485 communication with RE/DE support?
Thank you
