## Description

These macros enable compile time checks of the library version.

## Details

### EV_MAJOR_VERSION

    #define EV_MAJOR_VERSION (1)

The major version number of the EV library (e.g. in version 3.1.4 this is 3).

### EV_MINOR_VERSION

    #define EV_MINOR_VERSION (14)

The minor version number of the EV library (e.g. in version 3.1.4 this is 1).

### EV_MICRO_VERSION

    #define EV_MICRO_VERSION (1)

The micro version number of the EV library (e.g. in version 3.1.4 this is 4).

### EV_CHECK_VERSION()

    #define             EV_CHECK_VERSION(major,minor,micro)

Macro to check the library version at compile time. It returns `1` if the version of EV is greater or equal to the required one, and `0` otherwise.

`major` : | required major version
`minor` : | required minor version
`micro` : | required micro version
