Here is the sample code - for Portenta H7 M7 core. If you load it into Visual Studio - you should see #include rtos underlined (the include part), as well as SHTC3 references, and I2C_Mutex calls.

Thanks

Code (c++):

#include "arduino.h"
#include "mbed.h"
#include "rtos.h"
#include "ThreadDebug.h"

// Check we are using GDB Debugging and include the additional code
#ifdef VM_DEBUG_GDB
#include "ThreadDebug.h"
UsbDebugCommInterface debugComm(&SerialUSB);
ThreadDebug          threadDebug(&debugComm, DEBUG_BREAK_IN_SETUP);
// Set to DEBUG_NO_BREAK_IN_SETUP to prevent automatic stop in setup
#endif

#include "SparkFun_SHTC3.h" // Click here to get the library: http://librarymanager/All#SparkFun_SHTC3
#include <Wire.h>
SHTC3 mySHTC3;             // Declare an instance of the SHTC3 class

using namespace mbed;
using namespace rtos;

Mutex I2C_Mutex; // Required each time I2C bus will be used

Thread sensorThread;

const int LED_ON = LOW; // Voltage level is inverted
const int LED_OFF = HIGH;

void loop() {
// put your main code here, to run repeatedly:
ThisThread::sleep_for(osWaitForever);
}

void task_sensor() {
int i = 0;
int j = 0;

float Temp, RH;

// Setup I2C port
// Will need a mutex on I2C

for (;;) {

I2C_Mutex.lock();
mySHTC3.update();

RH = mySHTC3.toPercent();
Temp = mySHTC3.toDegC();

//Read SHCT3 sensor in here
// Serial.print("RH = ");
// Serial.print(mySHTC3.toPercent());                      // "toPercent" returns the percent humidity as a floating point number
// Serial.print("%, T = ");
// Serial.print(mySHTC3.toDegC());                         // "toDegF" and "toDegC" return the temperature as a flaoting point number in deg F and deg C respectively
// Serial.println(" deg C");

I2C_Mutex.unlock();

digitalWrite(LEDR, LED_ON); // Turn green LED on
ThisThread::sleep_for(1000);
digitalWrite(LEDR, LED_OFF); // Turn green LED off
ThisThread::sleep_for(1000);
ThisThread::sleep_for(10);

i++;
j += 2;

}
}

void setup() {
// put your setup code here, to run once:

// Function for device
// Modbus Server (slave)
// Web Server - show only data one way
// Bluetooth communication with Android / iOS / .NET - for device confguration
// Sensor Interfaces - multiple I2C sensors read by device
// Sensor average data =- 1 minute interval per sensor, and 60 minute interval per sensor
// LCD panel display to display data - press any sensor and maybe will show a graph - maybe

//Serial.begin(115200);

//Serial.print("Program Start\n");

Wire.begin();

mySHTC3.begin();

pinMode(LEDR, OUTPUT); // Set green LED as output

delay(5000);

sensorThread.start(task_sensor);

}
