1、功能说明
    此例程展示蜂鸣器模块的用法。
    
2、使用环境

    软件开发环境：KEIL MDK-ARM V5.34.0.0
    硬件开发环境： 
        N32G05x系列：
            基于评估板N32G05xRBQ7_STB V1.0开发
        N32G05x系列：
            基于评估板N32G05xRBL7_STB V1.0开发


3、使用说明
    1、时钟源：HSE+PLL
    2、主时钟：64MHz
    3、输出端口：
            BEEPR_OUT: PB14

    4、测试步骤与现象
       a，编译下载代码复位运行
       b，用示波器查看波形，查看输出波形频率

4、注意事项
     由于BEEPER输出时钟源为LSI，所以输出波形频率会有一点偏差。

1. Function description
    This example shows the usage of the buzzer module.
    
2. Use environment

	Software development environment: KEIL MDK-ARM V5.34.0.0
    Hardware development environment:
         N32G05x series:
            Developed based on the evaluation board N32G05xRBQ7_STB V1.0
         N32G05x series:
            Developed based on the evaluation board N32G05xRBL7_STB V1.0

3. Instructions for use
     1. Clock source: HSE+PLL
     2. Main clock: 64MHz
     3. Output port：
                BEEPR_OUT: PB14

     4. Test steps and phenomenon
        a. Compile and download the code to reset and run.
        b. Use the oscilloscope to view the waveform and check the output waveform frequency

4. Matters needing attention
    Since the BEEPER output clock source is LSI, the output waveform frequency will be slightly deviated.
