Using the Buzzer Output GPIO7
The GPIO7 pad, when configured as Buzzer Output, is controlled
by the GE864-QUAD Automotive V2 module and will drive with
appropriate square waves a Buzzer driver.
This permits to your application to easily implement Buzzer
feature with ringing tones or melody played at the call
incoming, tone playing on SMS incoming or simply playing a
tone or melody when needed by your application.
A sample interface scheme is included below to give you an
idea of how to interface a Buzzer to the GPIO7:
NOTE:
To correctly drive a buzzer a driver must be provided, its
characteristics depend on the Buzzer and for them refer to
your buzzer vendor.
