    Hello,

    I have some problems with the RS485 interface and hope you can help me.

    in the following code:

    https://github.com/CONTROLLINO-PLC/CONTROLLINO_Library/blob/master/MAXI/DemoRS485/DemoRS485.ino

    describe the use of the RS485 interface. How would I have to change the code so that I first send a data byte

    for example

    Code:

    byte a_reset[] = { 0xAA, 0x02, 0x06, 0x00, 0x02, 0x4D, 0x00, 0x01, 0x00, 0x8F, 0xE1, 0x55 };


    via the Controllino/Master via RS485 and only then receive the answer from the device/slave?

    Thank you

    Yours sincerely

    Martin

    Hello,

    I am sorry, but I am not sure how to help you. Maybe you should ask more concrete question?

    Or share with us your sketch?

    Thanks,

    Lukas
