Hello everyone,

I am trying to interface my Arduino Nano, MPU6050 and Simulink.

My Matlab;

MATLAB Version: 9.9.0.1592791 (R2020b) Update 5
Operating System: Microsoft Windows 10 Pro Version 10.0 (Build 19042)
Java Version: Java 1.8.0_202-b08 with Oracle Corporation Java HotSpot(TM) 64-Bit Server VM mixed mode

I have downloaded two Add-Ons;

MATLAB Support Package for Arduino Hardware
Simulink Support Package for Arduino Hardware

I have done pretty much anything I have tried with the block provided by the Simulink Support Package Blocks and they are such as;

Blink
Analog Read from a Potentiometer
Read raw data from my MPU6050 with the Library>Simulink Support Package for Arduino Hardware>Sensors> MPU6050 IMU Sensor Block,

I have also tried to read data from my MPU6050 from the script, that works just fine;

Connect to MPU-6050 sensor on Arduino hardware I2C bus - MATLAB (mathworks.com)

What my real problem is that I need Pitch and Roll angles from my IMU and under the Simulink Support Package I have found the example for this as;

Pitch and Roll Calculation on Arduino Using IMU Sensor - MATLAB & Simulink Example (mathworks.com)

Following the instructions, I have opened the prepared file with the command;

open_system('arduino_imu_pitch_roll_calculation');
which arduino_imu_pitch_roll_calculation

C:\ProgramData\MATLAB\SupportPackages\R2020b\toolbox\target\supportpackages\arduinotarget\arduinotargetdemos\arduino_imu_pitch_roll_calculation.slx

cd C:\ProgramData\MATLAB\SupportPackages\R2020b\toolbox\target\supportpackages\arduinotarget\arduinotargetdemos

Just to be sure that File Directory is the same with the example file. But did not work.

Then I thought directly running from the example directory might be the problem then I made a copy of the .slx and run it in another directory by changing the Line 21;

imuObj = mpu9250(arduinoObj);

to the

imuObj = mpu6050(arduinoObj); % My IMU is MPU6050

and run the program with Choosing the device settings just as I did in the previous examples and this is the Error message I got;

What should I do, anyone facing same problem ?

Thanks for any suggestions

Hi,

Did you solve this problem by any chance?

Joseph Russo on 7 Jan 2023

If you're still having this problem, check to see if you have a compiler installed... I just ran into the same issue.

In the command window, type the following:

mex -setup

if it tells you that you don't have a compiler, then thats most likely the issue. Follow the instructions on how to download the free one off Mathworks.
