pyserial

Ok so I have the code below for real-time graphing some data from an embedded device received over serial. It's not meant to be a production tool but rather an internal eng tool, hence it's not terribly user-friendly. The problem is that no matter what I do, I can't get minor grid lines to appear, even though here they are set to True, which=both . I can do anything I want to the major grid lines but the minors won't appear. Any ideas? Here is the code: import numpy as np from matplotlib import pyplot as plt from matplotlib import animation import serial SERIAL_PORT_NUM=9 ...a bunch of

Good morning! Recently I bought an Arduino board to make sort of "light control" in my room. Here is the code of the firmware I wrote: int control = 0; int pin = 0; void setup() { Serial.begin(9600); for(pin = 0; pin <= 13; pin++) pinMode(pin, OUTPUT); } void loop() { control = Serial.read(); if (control > 0 && control <= 13) digitalWrite(control, HIGH); if (control < 256 && control >= (256-13)) digitalWrite((256-control), LOW); } After that, I used pySerial from Python interpreter to control the pins, and everything was working fine. Here is a piece of interpreter output: Python 2.6.5 (r265

In Python 3 I imported the pySerial library so I could communicate with my Arduino Uno by serial commands. It worked very well in Python 2.7 but in Python 3 I keep running into a error it says this TypeError: unicode strings are not supported, please encode to bytes: 'allon' In Python 2.7 the only thing I did differently is use raw_input but I don't know what is happening in Python 3. Here is my code import serial, time import tkinter import os def serialcmdw(): os.system('clear') serialcmd = input("serial command: ") ser.write (serialcmd) serialcmdw() ser = serial.Serial() os.system('clear')

I know that I can use e.g. pySerial to talk to serial devices, but what if I don't have a device right now but still need to write a client for it? How can I write a "virtual serial device" in Python and have pySerial talk to it, like I would, say, run a local web server? Maybe I'm just not searching well, but I've been unable to find any information on this topic. this is something I did and worked out for me so far: import os, pty, serial master, slave = pty.openpty() s_name = os.ttyname(slave) ser = serial.Serial(s_name) # To Write to the device ser.write('Your text') # To read from the

I am trying to automate serial connection without clicking on button. When the gui load, serial should be read immediately and refreshed at interval without using the mouse to trigger any button (that is auto read in and updated). How possible is this? See script and GUI below.. import schedule import serial import sys from PyQt5 import uic, QtWidgets qtCreatorFile = "gui.ui" Ui_MainWindow, QtBaseClass = uic.loadUiType(qtCreatorFile) estudiantes = [' ',' ',' ',' '] ser = serial.Serial('COM9', baudrate=9600, timeout=1) class MyApp(QtWidgets.QMainWindow, Ui_MainWindow): def __init__(self):

Using Python 3.3 and pySerial for serial communications. I'm trying to write a command to my COM PORT but the write method won't take my string. (Most of the code is from here Full examples of using pySerial package What's going on? import time import serial ser = serial.Serial( port='\\\\.\\COM4', baudrate=115200, parity=serial.PARITY_ODD, stopbits=serial.STOPBITS_ONE, bytesize=serial.EIGHTBITS ) if ser.isOpen(): ser.close() ser.open() ser.isOpen() ser.write("%01#RDD0010000107**\r") out = '' # let's wait one second before reading output (let's give device time to answer) time.sleep(1) while

I've got a Python program which is reading data from a serial port via the PySerial module. The two conditions I need to keep in mind are: I don't know how much data will arrive, and I don't know when to expect data. Based on this I have came up with the follow code snippets: #Code from main loop, spawning thread and waiting for data s = serial.Serial(5, timeout=5) # Open COM5, 5 second timeout s.baudrate = 19200 #Code from thread reading serial data while 1: tdata = s.read(500) # Read 500 characters or 5 seconds if(tdata.__len__() > 0): #If we got data if(self.flag_got_data is 0): #If it's
