need help for arduinoscope

Projects General Guidance

i am doing arduinoscope .the program in the arduino works well.but when running processing program ,it shows error as

the func id() does not exist.
can anybody suggest any help for this please??

arduino program:

/*
this goes on your arduino
for use with Processing example SimpleSerialArduinoscope

*/

// holds temp vals
int val;

void setup() {
 // set 2-12 digital pins to read mode
 for (int i=2;i<14;i++){
   pinMode(i, INPUT);
 }
 
 Serial.begin(115200);  
}

void loop() {  
 // read all analog ports, split by " "
 for (int i=0;i<6;i++){
   Serial.print(analogRead(i));
   Serial.print(" ");
 }
 
 // read all digital ports, split by " "
 for (int i=2;i<14;i++){
   Serial.print(digitalRead(i));
   Serial.print(" ");
 }
 
 // frame is marked by LF
 Serial.println();
}

processing:

/*
This is a basic serial arduinoscope.
*/

/*

Serial data comes in, in the format

1 23 34 4 5 76
1 23 34 4 5 76
1 23 34 4 5 76
1 23 34 4 5 76

(space seperates pin=data, LF-seperated frame data)

can anybody suggest any help for this please??

Please read this:-
How to use this forum
Because your post is breaking the rules about posting code.

okay ...modified the code..thanks for the tip

Thanks.

Now also in those instructions you will see it asks for links to any library that you use. So can you post a link to where you got the arduinoscope library from.
Without this I can not run the code you posted to look for why there might be an error. In fact:-

the func id() does not exist.

Indeed the id() function is not mentioned at all in that code so the only reference to it must be in the missing library.
Finally there are three major revisions of Processing, which one are you using? Is it the one this code was written for?

Thankyou it worked!!! installed earlier version of controlp5 and processing.. :slight_smile:
