DWM-CooperKit Buzzer

DWM14121903

Cooperkit Buzzer is connected to the digital I / O port, when the output is low, buzzer will give a long sound. If it is connected to an analog pulse width modulation (PWM) output , the buzzer can produce a variety of tones, which can be made into the speaker of electronic organ.

}

How to port

This demo is based on CoX M051 library, if you want to port to other CoX library, Just do the simple step below.
The Buzzer is commucate with GPIO pin, so in the CooperKit_Buzzer.h file, the port configuration group provides the gpio pin connection Macro to user for port. For example your Button signal pin is connect to GPIOA PIN2, you should modify the Macro as:

//*****************************************************************************
//
//! \addtogroup CooperKit_Buzzer_Config
//! CooperKit Buzzer configurator
//! @{
//
//*****************************************************************************
//
//! Configure the pin connection of CooperKit Buzzer
//
#define CooperKit_Buzzer_PIN     PA2

//
//! Set the effective output level of CooperKit Buzzer to sound
//
#define CooperKit_Buzzer_EFFECTIVE_LEVEL                   \
                         
0
