或用下面代码发送HEX: 和上面的b'xxxxx'一样 ,这个data变量应该都是bytearray格式的 data = ('FE0F000000080100B191').decode('hex') # Write data to serial NoOfBytes = COM_Port.write(data) # Write data to serial port 华为ar502h 的232串口为/dev/ttyO0 , 485串口为/dev/ttyO1, 详细测试代...
This module encapsulates the access for the serial port. It provides backends for Python running on Windows, OSX, Linux, BSD (possibly any POSIX compliant system) and IronPython. The module named “serial” automatically selects the appropriate backend. 该模块封装了对串行端口的访问。 它提供了在Wi...

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 ...
I'm trying to pass in information from a python script run on my computer to my psoc device (I'm on a Windows computer). I'm currently trying to open a Serial com port in my python script, and write to that com port. (Below is what I added to my python script. F...
data_to_write=b'Hello, world!'# 要写入的数据,以字节形式表示ser.write(data_to_write) 1. 2. 7. 关闭串口设备 在使用完串口设备后,记得要关闭它,释放资源。 ser.close() 1. 类图 下面是本文中涉及到的类的类图: Serial-port: str-baudrate: int-bytesize: int-parity: str-stopbits: int+open(...
笔者这里使用的是QTCreator和Python来实现一个简单的串口上位机的开发的简单过程,使用到Python,之前记录的Qt 使用C++写上位机也记录一篇文章,大家感兴趣的话可以看看。从零开始编写一个上位机(串口助手)QT Creator + C++ 这里我使用Python写上位机主要的原因就是Python强大的数据抓取能力以及数据处理能力...
在python3.5中使用serial模块进行串口通信,通过while 1循环进行持续性的设备通信,但是第一个设备完成之后对下一个设备进行通信会有问题:Attempting to use a port that is not open 一下是我的代码: import serial import time import base64 import hmac ...
