Hello

I want to perform the SCI ECHO BACK task. For this I want to ask, should I connect gpio28 directly with pin 3 of DB9 cable and gpio29 directly with pin 2 of DB9 cable?

Thank you

    hi ,

    Yes connect them directly . Are you seeing any issues ?

    //! Connect the SCI-A port to a PC via a transceiver and cable.
    //! - GPIO28 is SCI_A-RXD (Connect to Pin3, PC-TX, of serial DB9 cable)
    //! - GPIO29 is SCI_A-TXD (Connect to Pin2, PC-RX, of serial DB9 cable)

    Regards.
