例如read和write,也支持readline等. 支持二进制传输,没有null消除,没有cr-lf转换. 有关Python的环境配置请参考: Windows 7下Python Web开发环境搭建笔记 而 pip 是随 Python 一同安装的,如下
This module encapsulates the access for the serial port. It provides backends for Python running on Windows, Linux, BSD (possibly any POSIX compliant system), Jython and IronPython (.NET and Mono). The module named "serial" automatically selects the appropriate backend. It is released under a ...

此声明不允许我们使用Arduino函数,例如“writeDigitalPin,writePWMDutyCycle'., 正如我在评论中提到的,首先清除端口并连接串行端口仍然很重要。 最后,声明Arduino能够使用其功能的真正方法如下: app.a = arduino(app.SerialPortsDropDown.value, 'Tag of your arduino card'); Python使用threads进行客户端-服务器...
