SimpleSerialArduinoscope.pde "error"

[HalleuYah]

Good evening, I am Rinaldy from Indonesia.
I was experimenting with arduino atmega 2560 to make an oscilloscope using arduino.
When I run code processing, I get an error message "The Function id() does not exist"

as shown in the picture below.
Thank you for the help

I'm not sure since you are not providing enough context in that screenshot above. Also, that line of code you are referencing has nothing to do with the Processing Arduino library. However if you provide the full code I may still be able to help if you have not already found the answer elsewhere.

here is the complete code
this would be a button press function. Unfortunately, I didn't get it
just use it...

Try changing port = new Serial(this, Serial.list()[0], 115200);
to
port = new Serial(this, Serial.list()[0], 57600);

[JoeAndrew]

Unfortunately not! My port is / dev / ttyUSB0, so I handle:
port = new Serial (this, Serial.list () [4], 115200);
It works in any other Processing program, but I can't start it...
no matter I stay at gtk, it was just an outbreak
once enough :)

[soundanalogous]

Does the arduinoscope library use Firmata as a dependency?
