Library using HardwareSPI class

Hi,

I'm trying to implement a library that'll use HardwareSPI class.

Is it better/recommended to declare HardwareSPI spi(1) and send the object to my class or inherit HardwareSPI class inside my library class?

Also, I'm having hard time finding a way to pass spi(1) because of the parameter on constructor.

Thanks,

Figured out by myself, this is called C++ initialization lists.

.h file:

class SPIEEPROM : public HardwareSPI
{
public:
        SPIEEPROM(uint32 spi_num);
}

.cpp file:

SPIEEPROM::SPIEEPROM(uint32 spi_num) : HardwareSPI(spi_num) {
        eeprom_type = 0;
        address = 0;
}

Now you can access SPI methods using this->begin(spi_parameters) per example.
