Arduino波特率设置指令如下: codertarget.arduinobase.registry.setBaudRate(gcs,115200) 图1.21 串口通信波特率设置 在“HARDWARE”栏中设置的效果如图1.22所示,其中"Stop Time"设置为"inf"模型可以一直运行,然后点击“Monitor & Tune”按钮运行等待程序编译下载到目标硬件上,最终硬件在环运行成功的效果如图1.23所示。 图...

为避免这种干扰,我实验下来的方法是:每个客户端在发送数据之前先setTADDR到一个无效且唯一的地址,在send之前那一刻再使用setTADDR将地址设置到服务端的地址,发送完成后马上setTADDR到那个无效地址。 3、Arduino与Android通过usb通讯 利用usb-serial-for-android这个开源项目。注意,两侧的baudrate要设置一致;android端读取...
因此,您可以创建get()和set()方法来查看和更改这些值。在 Python 中,属性是公共的,可以通过简单的class.attribute调用来访问或更改。Python 属性不能成为私有属性;然而,Python 中的传统是在希望私有的属性前面加上下划线。这向其他开发人员表明,该属性应该被视为私有属性,不能在类的方法之外进行修改。
