这里以uart0为例P0.2对应MCU_ARD_PWM11P0.3对应MCU_ARD_PWM12 模块连接图
右侧排母从上往下第6、7引脚分别对应uart0 TXD、RXD 状态指示灯
板子有两个自主控制的绿色LED通过上拉方式接入GPIOMCU_USER_LED1对应P0.0本次实验使用它来指示uart0的数据接收状态

}打开串口调试工具打开对应的COM口串口设置和上面的代码保持一致波特率115200、数据位8位、停止位为1位、奇偶校验位为无 在RT-Thread Studio初始化uart0使用msh终端输入uart0_setup命令 初始化成功可以在串口调试工具看到以下信息 自定义串口消息点击发送按钮可以看到发出去的消息被开发板转发了回来而LED也随即闪了一下 接收GPS模块定位数据
通过uart0连接ATGM332D GNSS模块实物连接图如下 编码实现uart0串口通信注意GNSS模块的波特率默认为9600其它跟上面的example保持一致
