Hello,

What is the most efficient way to control the direction of RS485 data with PSOC4100 ?

Thank you

Do you mean the absence of tx_en pin in SCB UART?

This was discussed here: SCB mode uart to RS485

I use my simplified hardware version.

It works at speeds up to 115200 baud and a short cable length (up to 1.5m)

circuit below:

Hi PeGu_352656​,

Could you please elaborate your question? Are you referring to the flow control for handshaking in serial communication?
