硬件概览

它是如何工作的？

BUZZ 2 Click基于CMT-8540S-SMT，这是来自CUI Devices的磁性蜂鸣器换能器。蜂鸣器的共振频率为4kHz。该点击板设计为可以使用3.3V或5V电源运行。mikroBUS™线上的PWM引脚控制CMT-8540S-SMT磁性蜂鸣器。您可

以使用我们编译器支持的Sound库来创建不同的声音模式，或利用微控制器内部的PWM模块来为蜂鸣器创建信号。信号频率决定声音的音调，而占空比决定振幅（声音大小）。这个Click board™可以通过VCCIO SEL跳线选择使

用3.3V或5V逻辑电压级别，这样，3.3V和5V能力的MCU都可以正确使用通信线。此外，这个Click board™还配备了一个包含易于使用的功能和示例代码的库，可以作为进一步开发的参考。

/*!
 * @file main.c
 * @brief Buzz2 Click example
 *
 * # Description
 * This example demonstrates the use of Buzz 2 click boards.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger.
 *
 * ## Application Task
 * Plays the Imperial March melody. Also logs an appropriate message on the USB UART.
 *
 * @note
 * 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.
