How to print out the the value of the register

[krupis]

Hello. I am looking into registers and learning various operations with them. I am using LIS3DH accelerometer sensor with the adafruit library.

For some reason, I am having a lot of troubles trying to print out the value of the register. For example, I want to print CTRL1_REG of the LIS3DH.

Inside Adafruit_LIS3DH.cpp file, I have created my own function for reading the register:

Adafruit_BusIO_Register Adafruit_LIS3DH::read_register(int register){
    Adafruit_BusIO_Register reg_to_read = Adafruit_BusIO_Register(
    i2c_dev, spi_dev, ADDRBIT8_HIGH_TOREAD, register, 1);
    return reg_to_read;

}

Simply, all I want to do is pass the value of the register to the function, and the function would then return me a number or hex value so I know what is set for this register. I have tried the above but I am not fully sure whether I can use the type Adafruit_BusIO_Register as a regular numbe or hex. Is that possible?

In my main arduino code, I call:

  Adafruit_BusIO_Register reg_to_read;
  reg_to_read = lis.read_register(LIS3DH_REG_CTRL4);
  Serial.println(reg_to_read);

But there is an error :

no matching function for call to 'Adafruit_BusIO_Register::Adafruit_BusIO_Register()'

Any help is appreciated. Please suggest me a simplest way how to read a register and print out using serial print
