        <description>如何在官方IDE中添加LGT8F328P的开发板

1、首先打开IDE，点击文件中的首选项

2、在附加开发板管理器网址中添加网址：

&lt;https://github.ocrobot.com/down/LGT8FX/package_lgt8fx_index.json&gt;


3、最后在工具——开发板——开发板管理器中找到LGT8F328P的包，选择最新版本，下载一下LGT的开发板即可！</description>

        <description>8F328P的DAC使用

ALPHA 8F328P具有一路8位DAC，我们介绍一下，怎样使用DAC。

需要注意的是，ADC和DAC使用的是同一个基准源，如果你改变基准源的话是两个所参考的基准源同时改变。

程序

        <description>8F328P输出时钟频率

我们有时需要输出系统时钟，用示波器或者其他仪器来检测系统时钟的精确度。

8F328P可以把系统时钟输出在PB0管脚，也就是D8管脚上。


void setup() {
  CLKPR |= 0x20; // 设置CKOEN0寄存器为1，系统时钟在PB0脚上输出
}

void loop() {
