how i read data from arduino in simulink real time?

//Current

#include <Wire.h>

#include <Robojax_WCS.h>

#define MODEL 12 //see list above

#define SENSOR_PIN A0 //pin for reading sensor

#define SENSOR_VCC_PIN 8 //pin for powring up the sensor

#define ZERO_CURRENT_LED_PIN 2 //zero current LED pin

#define ZERO_CURRENT_WAIT_TIME 5000 //wait for 5 seconds to allow zero current measurement

#define CORRECTION_VLALUE 164 //mA

#define MEASUREMENT_ITERATION 100

#define VOLTAGE_REFERENCE 5000.0 //5000mv is for 5V

#define BIT_RESOLUTION 10

#define DEBUT_ONCE true

Robojax_WCS sensor(MODEL, SENSOR_PIN, SENSOR_VCC_PIN, ZERO_CURRENT_WAIT_TIME, ZERO_CURRENT_LED_PIN, CORRECTION_VLALUE,

MEASUREMENT_ITERATION, VOLTAGE_REFERENCE, BIT_RESOLUTION, DEBUT_ONCE);

//Motor Driver

int enA =7; //mendeklarasikan pin enA tehubung ke pin 3 arduino

int in_1 = 8;//mendeklarasikan pin in_1 tehubung ke pin 4 arduino

int in_2 = 9;//mendeklarasikan pin ein_2 tehubung ke pin 5 arduino

//Encoder

int PinEnCA=3 ;

int PinEnCB=4 ;

float rpm;

int pulse;

float deltaTime, now, lastTime;

int Gear=44.9, PPR=7;

char charValue[5];

String stringData;

void setup()

{

//Motor Driver

//Mendeklarasikan bahwa pin-pin tersebut bekerja sebagai OUTPUT

pinMode(enA,OUTPUT);

pinMode(in_1,OUTPUT);

pinMode(in_2,OUTPUT);

//Encoder

pinMode(PinEnCA,INPUT);

pinMode(PinEnCB,INPUT);

attachInterrupt(digitalPinToInterrupt(PinEnCA),callbackInterrupt, RISING);

//Current

Serial.begin(115200);

sensor.start();

Serial.print(sensor.getModel());

}

void loop()

{

gerak_1(); //memenaggil fungsi gerak 1

//RPM

now=millis();

deltaTime=now-lastTime;

if (deltaTime>=50){

rpm=(pulse*60.0*4000.0)/(Gear*PPR*deltaTime);

pulse=0;

lastTime=now;

}

Serial.print(rpm);

Serial.print (" ");

sensor.printCurrent();

delay(100);

}

void gerak_1(){

analogWrite(enA,255); //mengatur tegangan ke motor sebesar 20(0-255) dari tegangan input

//menentukan arah putar

digitalWrite(in_1,HIGH);

digitalWrite(in_2,LOW);

}

void callbackInterrupt(){

pulse++;

}

this is my code in arduino IDE, how can I read the "current" and "rpm" values in the simulink code in real time? by using the library in the code

Hi Muhammad

I understand that you want to read the “current” and “rpm” values in the real time Simulink.

To read the values in Simulink, follow the below steps:

1. Install the support for Arduino Hardware.
2. Review the Arduino board library from the Simulink library browser and choose the required blocks for your model.
3. Create a Simulink model for Arduino hardware.
4. Configure and run the model on supported hardware.

You can refer to the below video, to know more about Simulink IO on Arduino.:

To get started with the Arduino hardware in Simulink, refer to the following documentation:

Hope this helps!
