Need to control RTS and CTS

[Hiren Bhuva]

Hello community,

I need to control RTS and CTS signals in my application.

But, It looks like STM internally controls these signals.

Can anyone suggest better way to control them in my application.

Thanks,

The RTS and CTS pins are directly supported by the STM32 UART peripheral by enabling hardware flow control.

Next time, please include your chip part number.

Thanks @TDK​  for quick response,

I am using STM32F401RET6 MCU.

I need to take decision when CTS is asserted. Can I control them in application?

Thanks,

Hiren

Yes, look at "Hardware flow control" in the reference manual.
