I2C issue with nrf52840 DK

[thanosPr]

Hello,

I am trying to learn bluetooth using nrf52840 USB dongle. I have created an application from sample beacon and i would like to use I2C to implement my own driver about a sensor.

I have succesfully configured and bind the node in the device tree.

According to same examples in net, i notice that they enable CONFIG_I2C_1=y

This option cannot be set in my application, due to there are missing depedencies I2C_ESP32. I cant understand why this depedency is needed.

I appreciate if you could help me a little bit about my issue.

bool initialize_sht21_driver(void)
{
    sht21_dev = DEVICE_DT_GET(DT_NODELABEL(i2c1));

    bool ret = device_is_ready(sht21_dev);
    if(ret)
    {
        printk("device is ready for use %d\n", ret);
    }
    else
    {
        printk("device is NOT ready for use %d\n", ret);
        return false;
    }


    sht21_dev = device_get_binding(DEVICE_DT_NAME(DT_NODELABEL(i2c1)));
    if(sht21_dev == NULL)
    {
        printk("device get binding returns NULL!!\n");
        return false;
    }

    ret = i2c_configure(sht21_dev, I2C_SPEED_SET(I2C_SPEED_STANDARD));
    if(ret != 0)
    {
        printk("i2c configuration issue!!\n");
    }
    return true;
}
