EE_VERSION fails on MLX90632_XTD_RNG_KEY at mlx90632_init #32

Hello, I'm using a extended device.

It returns an error on mlx90632_init

if ((eeprom_version & 0x7F00) == MLX90632_XTD_RNG_KEY)
    {
        return ERANGE;
    }

What does it mean?

thanks I understand now :)

It's a positive value, so it's not an error. And to keep it compatible somehow with errno.h, we reused the ERANGE name (Which wrongly indicates ErrorRANGE, but you could as well view is as ExtendedRANGE ).
