Functions

func CloseCore

func CloseCore()

CloseCore performs core dependencies close sequence.

func Execute

func Execute(fn func() error, msg string)

Execute executes `fn` function and in case of error logs it. Use `msg` to specify details of error to wrap by.

func InitCore

func InitCore()

InitCore performs core dependencies initialization sequence.

func MustExecute

func MustExecute(fn func() error, msg string)

MustExecute executes `fn` function and in case of error logs it, followed by a call to os.Exit(1). Use `msg` to specify details of error to wrap by.

func MustUnmarshalFromConfig

func MustUnmarshalFromConfig(key string, v interface{})

MustUnmarshalFromConfig retrieves config block by given `key` and decodes it into given structure `v`. In case of unmarshalling error occurrence it will log fatal error.

func NtoI2cBusName

func NtoI2cBusName(n int) string

NtoI2cBusName returns I2C bus name based on specified `n` number.

func NtoPinName

func NtoPinName(pin int) string

NtoPinName returns GPIO pin name based on specified `pin` number.

func UnmarshalFromConfig

func UnmarshalFromConfig(key string, v interface{}) error

UnmarshalFromConfig retrieves config block by given `key` and decodes it into given structure `v`.
