So I am actually trying to interface my raspberry pi with a motor driver too run two motors using a raspberry pi camera v1.3 but there seems to be some problem related to gpio.

I am using Raspbian so I did try

sudo apt-get update

sudo apt-get upgrade

but updating does not seem to help me solve the problem
neither does updating my gpio interface.

Here is a code I am using to light up a led on my board as soon as the camera finds something.

import processing.io.*; // use the GPIO library

// store the desired state of the LED in a variable
boolean ledOn = false;

void setup() 
 // set pin 17 as an output:
 GPIO.pinMode(17, GPIO.OUTPUT);


void draw() 
 if (ledOn == true) // If the desired state is on, then:

 // turn the LED on:
 GPIO.digitalWrite(17, GPIO.HIGH);

 // and set the background red:
 background(255, 0, 0);
 

 else // otherwise:

 // turn the LED off:
 GPIO.digitalWrite(17, GPIO.LOW);

 // and set the background black:
 background(0, 0, 0);
 


void mouseClicked() 
 // When the mouse is clicked, store the opposite of
 // ledOn into ledOn, which toggles ledOn:
 ledOn = !ledOn;

The code compiles successfully but it returns a error saying

/sys/class/gpio/gpio4/direction: No such file or directory

UPDATE

Reinstalling the whole operating system from scratch seems to fix the problem.

  @PLASMAchicken a simple code such as this one (projects.raspberrypi.org/en/projects/introduction-to-processing/…) gives the same error i just can't seem to interface with the gpio at all.

  Does that file or directory exist? Sounds like you need to track down what file is expected, and then make sure that file is present.

  @KevinWorkman it seems to be an os related problem, so I just reflashed the whole operating system back and it worked :)
