    Terminate a data stream

    Hi everyone.

    I have a situation where i need to terminate a data stream after it has detected a long press (pressing a button for more than 1 second continuously without release).

    Breaking down the process, it should be something like this:

    Detect long press --> execute long press function --> terminate data --> wait until release (here, it basically doesnt do anything at all, but wait till its released and pressed again)

    Does anyone know how I can do this?

    It would really depend on how you were sending the stream

    Are you sending it all at once, or one byte at a time?

    Im sending by byte. on the oscilloscope, it would appear as if its transmitted the whole 32 bits. I have an issue where if i continuously press the button, it keeps on turning ON and OFF continuously until I let it go. I need it to just turn ON, then turn OFF then wait till i release then detect the button all over again.

    ASCII has some old values that were used to indicate the end of text, and another to indicate end of transmission, etc. Sounds like you could use those kind of sentinel values, in your data stream, to good effect.

    It sounds like you are not waiting for the user to let go of the button before doing anything else

    With states, you usually have a state after you have finished your processing to wait for the user to let go of the button

    Code:
    //Using switch based states...
    
      case wait_for_release:
        if (button == released)
        {
          state = first_state;
        }
        break;
