Re: rs485 driver #stm32

Careful, while that may work in some cases,
we've always needed to implement fast control of xmit/receive switching in the driver
to avoid multiple devices sometimes trying to drive the bus.

Can any Zephyr users/developers provide further information about driver support for RS-485??

Thanks,
Best Regards, Dave

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.

May be someone used zephyr for rs485 communication with RE/DE support?
