Buzzer Click is a compact add-on board for generating sound signals in various electronic applications. This board features the CPT-7502-65-SMT-TR, a piezoelectric buzzer transducer from CUI Devices, known for its efficient sound output and compact surface-mount design. The buzzer offers a sound pressure level of 65dB and consumes only 1mA of current, making it ideal for battery-powered devices. The board also features the MIKROE 'Click Snap' function, allowing for flexible installation and autonomous operation.
We provide a library for the Buzzer Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
This library contains API for Buzzer Click driver.
buzzer_cfg_setup
Config Object Initialization function. buzzer_init
Initialization function. buzzer_play_sound
This function plays sound on the buzzer. This example demonstrates the use of Buzzer click board by playing the Imperial March melody on the buzzer.
The demo application is composed of two sections :
Initializes the driver and logger.
Plays the Imperial March melody. Also logs an appropriate message on the USB UART.
The minimal PWM Clock frequency required for this example is the frequency of tone C6 - 1047 Hz.
So, in order to run this example and play all tones correctly, the user will need to decrease the MCU's main clock frequency in MCU Settings for the certain architectures in order to get the required PWM clock frequency.
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
