Functions
void	TOTP (uint8_t *hmacKey, uint8_t keyLength, uint32_t timeStep)
	TOTP Object, main object for the code generator.
void	setTimezone (uint8_t timezone)
	Set the timezone from UTC, Arizona is always -7, so this is what is hard encoded into main.
uint32_t	TimeStruct2Timestamp (struct tm time)
	Accepts a time struct from struct tm, returns it as a timestamp.
uint32_t	getCodeFromTimestamp (uint32_t timeStamp)
	Accepts a timestamp from uint32_t, returns the code in uint32_t.
uint32_t	getCodeFromTimeStruct (struct tm time)
	Accepts a timestamp from struct tm, returns the code in uint32_t, not used for the current project From the TOTP library.
uint32_t	getCodeFromSteps (uint32_t steps)
	Accepts a number of steps for a HMAC based code, not used for this project From the TOTP library.

Variables
uint8_t *	_hmacKey
uint8_t	_keyLength
uint8_t	_timeZoneOffset
uint32_t	_timeStep
