Hi, I keep getting #failed to generate all binary outputs message when using the S function block.

Hi. I am using an Arduino UNO with an adafruit 10 dof IMU. I am running an example sketch on using only the accelerometer,on Simulink using the S-function block. Every time I run it I keep getting this error message. I didnt post the whole code as it is very long, just the part showing the error.

Hi Guys, i just found out that it is not able to find the libraries specified for some reason even though i add them to the current path in Matlab. I dont know why it would do such a thing, would anyone have any idea?

 #include <Wire.h>

You had the .h in the wrong place

Thank you so much, I cant believe i missed that. I have fixed it but now I am getting the following error for some reason. Am I also supposed to declare the function that is used in the void loop and void setup?, because I would have thought it is declared within the library itself.

"../Accelerometer_wrapper.cpp"
../Accelerometer_wrapper.cpp: In function 'void Accelerometer_Outputs_wrapper(real_T*, const real_T*)':
../Accelerometer_wrapper.cpp:49:1: error: 'accel' was not declared in this scope
 accel.begin();
 ^
../Accelerometer_wrapper.cpp: In function 'void Accelerometer_Update_wrapper(const real_T*, real_T*)':
../Accelerometer_wrapper.cpp:67:3: error: 'accel' was not declared in this scope
   accel.getEvent(&event);
   ^
../Accelerometer_wrapper.cpp:71:9: error: assignment of read-only location '* y0'
   y0[0] = event.acceleration.x;
         ^
../Accelerometer_wrapper.cpp:72:9: error: assignment of read-only location '*(y0 + 4u)'
   y0[1] = event.acceleration.y;
         ^
../Accelerometer_wrapper.cpp:73:9: error: assignment of read-only location '*(y0 + 8u)'
   y0[2] = event.acceleration.z; 
         ^
gmake: *** [Accelerometer_wrapper.o] Error 1

The code I used in the S-function is the following, for the libraries:

#ifndef MATLAB_MEX_FILE
#include <Arduino.h>
#include <math.h>

#include <Wire.h>
#include <Wire.cpp>
#include <txi.h>
#include <txi.cpp>
#include <Adafruit_Sensor.h>
#include <Adafruit_LSM303_U.h>
#include <Adafruit_LSM303_U.cpp>

#endif

For the output:

if (xD[0]==1) {

    # ifndef MATLAB_MEX_FILE
    accel.begin();
    # endif
    }

As for the Discrete Update:

if (xD[0]!=1) {
  #ifndef MATLAB_MEX_FILE
    /* Get a new sensor event */ 
  sensors_event_t event; 
  accel.getEvent(&event);

    /* Display the results (acceleration is measured in m/s^2) */

    y0[0] = event.acceleration.x;
    y0[1] = event.acceleration.y;
    y0[2] = event.acceleration.z; 
    delay(500);

# endif
  xD[0]=1;
}

I am using an accelerometer and this code is supposed to give me 3 values through the scope, x,y and z. Any help is appreciated, thanks.

Which .h is accel declared in?

You should not be #include'ing a .cpp in this situation.
