Another One: Error Compiling for board Arduino Uno

[oxygen02]

I am using an Adafruit motor shield v2 to make a NEMA stepper motor move. I want to test the motor using the StepperTest example provided by the Adafruit library. I am getting this error: Error Compiling for board Arduino Uno. I have all my libraries installed, but I am still getting this compiling error. What am I missing?

If you're using IDE 1.8.x, there is a button "copy error messages" at the right in the orange bar.

Click it to copy and next paste it here between code tags.
Also post your code between code tags.

Inc ase you haven't read it yet, How to get the best out of this forum has a description how to use code tags.

Your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (nor for advice on) your project See About the Installation & Troubleshooting category.

Hi @oxygen02

welcome to the arduino forum

If you get a compiler-error provide all details for analysing the error

Hi newcomer, the Arduino-Forum community can be of great help. If the community is able to support you in a way that helps solving your problems depends on detailed information that you should provide. trying to be quick by posting a too short posting is just slowing down finding the solution. Because all that happends is that you are asked for the detailed information and have to provide it anyway. Only difference the answer and the solution comes later The most important thing is to pos…

Thank you for the guidance I will follow preferred format.

Here is the copied error:

This report would have more information with

option enabled in File -> Preferences.

Here is the code:

#include <Adafruit_MotorShield.h>

// Create the motor shield object with the default I2C address
Adafruit_MotorShield AFMS = Adafruit_MotorShield();
// Or, create it with a different I2C address (say for stacking)
// Adafruit_MotorShield AFMS = Adafruit_MotorShield(0x61);

// Connect a stepper motor with 200 steps per revolution (1.8 degree)

Adafruit_StepperMotor *myMotor = AFMS.getStepper(200, 2);


void setup() {
  Serial.begin(9600);           // set up Serial library at 9600 bps
  while (!Serial);
  Serial.println("Stepper test!");

  if (!AFMS.begin()) {         // create with the default frequency 1.6KHz
  // if (!AFMS.begin(1000)) {  // OR with a different frequency, say 1KHz
    Serial.println("Could not find Motor Shield. Check wiring.");
    while (1);
  }
  Serial.println("Motor Shield found.");

  myMotor->setSpeed(10);  // 10 rpm
}

void loop() {
  Serial.println("Single coil steps");
  myMotor->step(100, FORWARD, SINGLE);
  myMotor->step(100, BACKWARD, SINGLE);

  Serial.println("Double coil steps");
  myMotor->step(100, FORWARD, DOUBLE);
  myMotor->step(100, BACKWARD, DOUBLE);

  Serial.println("Interleave coil steps");
  myMotor->step(100, FORWARD, INTERLEAVE);
  myMotor->step(100, BACKWARD, INTERLEAVE);

  Serial.println("Microstep steps");
  myMotor->step(50, FORWARD, MICROSTEP);
  myMotor->step(50, BACKWARD, MICROSTEP);
}

I think I have everything that is needed. Can you let me know if I am missing anything?

thank you

The short error-text says this

Adafruit_MS_PWMServoDriver.h:27:10: fatal error: Adafruit_I2CDevice.h: No such file or directory

and the error-text explains

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

If you would have done the adjustements linked to in post #3
you would have already provided the detail information needed to analyse the error

I guess the Adafruit_MotorShield.h-library has dependencies that you did not install
If you install a library with the Arduino-IDE-library manager and this library has dependencies the library manager asks you if you want to install these other libraries too then you should choose yes.
