Detailed Description

Created on: Mar 26, 2019 Authors: Nikola Kosaric, Nate Hoffman, Brian Harlow, DJ Stahlberger

The following module utilizes the task manager and timing module in order to inact a buzzer to produce a sound at a determined frequency. The timing module is used to control the frequency of the sound produced and the task module is used to control the length of time the buzzer will sound.

In oder to utilize this module, first, the Buzzer_Init must be called. Then, the Buzzer_Sound function must be called in order to determine the frequency at which the buzzer will sound and the length of time the buzzer will sound. The channel used for the buzzer will be determined in the hardware abstraction layer.

void Buzzer_Init

(

void

)

initializes the buzzer module for use

Initializes the task manager and timing modules to allow the modules to be used within the Buzzer_Sound function
