            基于评估板N32G05xRBL7_STB V1.0开发

3、使用说明
    系统配置；
        1、时钟源：
            HSI=8M,AHB=64M,APB1=32M ,APB2=64M
        2、端口配置：
            PB13选择为模拟功能DAC OUT
        3、DAC：
            DAC选择软件触发，基准为4094，开启噪声模式，噪声幅值为1
        4、主循环：
            一直触发DAC 输出
    使用方法：
        1、编译后打开调试模式，利用示波器观察PB13输出波形
        2、全速运行时，可看到PB13输出大约3.3V电平

1. Function description
    1. The software triggers the DAC to output a level signal of 4094, and the noise amplitude is 1

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
    System Configuration;
        1. Clock source:
           HSI=8M,AHB=64M,APB1=32M ,APB2=64M 
        2. Port configuration:
            PB13 is selected as analog function, DAC OUT
        3. DAC:
            DAC selects software trigger, the benchmark is 4094, the noise mode is turned on, and the noise amplitude is 1
        4. Main loop:
            Always trigger DAC output
    Instructions:
        1. Open the debug mode after compiling, and use the oscilloscope to observe the output waveform of the PB13
        2. When running at full speed, you can see that the PB13 output is about 3.3V level
