I am having a lot of trouble having to change my dt files and receive errors every time i try to run a basic sample for the NCS . Is there any 'How to' that i can refer and build my solution

Hello Manas,

In order to get familiar with NCS I would recommend you to take a look at out DevAcademy.

	if (!device_is_ready(dev_i2c.bus)) {

		return;
	}

	uint8_t id_write[1] = {BME280_ID_REG};
	
	while (1)
	{
		i2c_write_read_dt(&dev_i2c,&id_write[0],1,&id_read[0],1);
		printk("%d\n",id_read[0]);
	}

overlay file

&i2c0 {
    
    mysensor: mysensor@76{
        compatible = "bosch,bme280";
        reg = < 0x76 >;
        label = "MYSENSOR";
    };
};

I am referring that only , and as a first step I am just trying to get the ID . I am not receiving any ID value.
