The method of controlling the serial peripheral interface fingerprint sensor and a mobile terminal apparatus and

Example disclose finger print sensor serial control method and apparatus and a mobile terminal peripheral interface of the present invention, wherein the method comprises: monitoring a fingerprint by the fingerprint sensor signal; signal when monitoring the fingerprint, the fingerprint sensor is turned on serial outer set interface. According to the present invention, the technical solutions provided in the embodiments, the fingerprint can be detected based on whether the signal to determine whether to turn on the fingerprint sensor serial peripheral interface, only if the signal detected fingerprint, the fingerprint sensor before opening serial peripheral interface. Serial Peripheral Interface avoid fingerprint sensor time to turn the system power consumption is increased.
