pyserial

问题 I am making a new post regarding this case because I was misunderstood in the first one... I have a code that reads the serial data from the Arduino and when some specific digits are pressed on the keyboard it writes these digits to the Arduino. This exact code works perfectly when I run it , it reads the serial data and I am able to write data to the Arduino. I use threading and PySerial library to achieve this. from pynput import keyboard import threading import serial import sys ser = None

问题 I have an MCU connected to the computer through a serial interface. The MCU might send data at regular intervals or very seldom depending on the type of sensor connected to it. So I want to have a python function that gets called whenever there is data incoming from the serial port instead of polling all the time. After reading a lot of similar questions (Small Example for pyserial using Threading. PySerial/Arduino, PySerial/interrupt mode, Python Serial listener, and so on), I came to the

问题 I'm curently working on a testbench for some pcbs. They can be controlled though USB. I wrote some python code to send (using pySerial) orders to one card via the serial device "/dev/ttyACM0" The problem is that I need to test 5 cards at a time which means I need to differentiate which card is controlled with “/dev/ttyACM*” and * depends on the pluging order (which I don’t control). I used “usb-devices” command to have the name of each physical usb port but I need to send orders to these via

问题 I am trying to write data to the first serial port, COM1, using PySerial. import serial ser = serial.Serial(0) print (ser.name) ser.baudrate = 56700 ser.write("abcdefg") ser.close() ought to work. However, I need to send 28 bytes of integers constantly; in the form 255 255 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 on loop, with each integer using one byte of data.

问题 I'm trying to use a Python3 script to control an Arduino Mega. This is a simple script to take a line from the keyboard and echo it back through the Arduino. I started with a working Python 2 script from http://petrimaki.wordpress.com/2013/04/28/reading-arduino-serial-ports-in-windows-7/. I can't seem to get the characters I sent back, which is probably a formatting issue. Is this a formatting issue? unicode to ASCII issue? How do I read/write binary/hex data and ASCII text with Python 3 and
