RS485 support

[fuchszeug]

Hi!

For my application I need automatic RS485 Write Enable output to connect to the interface IC. From the release notes I saw that the feature was added but then removed again in 1.16. Is there any plan to add this feature back at some point?

Thanks!

Because the subsequent chip series CH9344L/Q and CH348L/Q provide TNOW signals to support automatic RS485 control, it does not need to be switched through the driver or software, so the driver deletes this part of the code
