PyFirmata Button Doesnt Change Values

Im Using Pyfirmata For A While, And I Want To Connect A Joystick Button On It, I Made The Code (AI) And It Didnt Work, It Keeps Changing Like "True, False, False, True, True..." and doesnt do nothing, heres my python code (PS: im using standart_firmata)
from pyfirmata import *
import time
import speech_recognition as sr
import random
from math import *
class IA:
def __init__(self, board, maquina, analogx, analogy) -> None:
self.board = board
self.maquina = maquina
self.analogx = analogx
self.analogy = analogy
self.button = self.board.get_pin("d:8:i")
self.previous_button_state = 0
self.sr = sr.Recognizer()
def record(self):
with self.sr.Microphone() as source:
print("gravando")
self.sr.adjust_for_ambient_noise(source)
audio = self.sr.listen(source)
try:
frase = sr.recognize_google(audio,language='pt-BR')
frase = frase.lower()
pass
except sr.UnkownValueError:
self.maquina.say("Não Entendi")
self.maquina.runAndWait()
self.main()
if (frase == "olá"):
sentences = ["Olá","Opa","Eae","Oi","Haha Eae"]
sentence = random.choice(tuple(sentences))
self.maquina.say(sentence)
self.maquina.runAndWait()
def main(self):
while True:
print(floor(self.button.read()))
time.sleep(1)

If anyone can help me, i will be grateful, thanks.

problem with send() function using socket in python

I'm using socket in python between 2 laptop to send informations. But I have an error and i can't resolve it. (I'm a debutant in python). The problem is when i trierd to send information with send() function
Traceback (most recent call last):
File "client.py", line 60, in <module>
client.send(GetMyInfo.scan())
TypeError: send() argument 1 must be string or buffer, not None
Maybe the error is due my function Getinfo ?
I'm using a class with functions (listinfo() here).
Thx
Here is the code :

#afficher l'utilisateur actuel
print "Current user : {} \n".format(GetInfo.currentUser)
#afficher le path du repertoire actuel
print "Repertoire actuel : {} \n".format(GetInfo.rep_actuel)

update json external file in python dialog

Hello I am developing an application in python, my problem is that I am saving a json file and I am calling it in a QlistWidget inside a Dialog
[
{
"title":"El titulo",
"enabled":true,
"path":"path",
"id":"5"
},
{
"title":"El titulo 2",
"enabled":true,
"path":"path",
"id":"555"
},
{
"title":"El recontra titulo",
"enabled":false,
"path":"path",
"id":"5555"
},
{
"title":"El titulo",
"enabled":true,
"path":"path",
"id":"5"
}
]
Here I have the program running, I read the data correctly and I show them in a QlistWidget when I enter the dialog
GUI
the problem is when I update the json add more items, I close the dialog and return open but the list is not updated
here I leave my code

app.exec_()
the save and read function works perfectly, the code of both
import os
import json
def jsonSave(data, file):
with open("data/"+file+".json", "w") as outfile:
json.dump(data, outfile)
def jsonOpen(file):
if os.path.exists('data/'+file+'.json') == True:
with open("data/"+file+".json", 'r') as json_file:
data = json.load(json_file)
else:
data = {}
data = []
return data
I'm using
- python 3
-pyQt5

The problem is caused by the fact that the data load is only given in the constructor, once the data is not updated since a new recharge is not done, what must be done is to create a method that the QListWidget must Reload whenever necessary or add the new item directly to the QListWidget, given the above, I have implemented the following code:
class Dialogo(QDialog):
def __init__(self, item):
QDialog.__init__(self)
uic.loadUi("menu/" + item + ".ui", self)
if item == 'addItems':
self.load()
self.saveitem.clicked.connect(self.save_items)
self.cancelbtn.clicked.connect(self.reject)
def load(self):
self.listitems.clear()
items = DB.jsonOpen('items')
for p in items:
self.listitems.addItem(p['title'])
def save_items(self):
data = DB.jsonOpen('items')
title = self.title.text()
id = self.id.text()
enabled = self.status.isChecked():
data.append({
'id': id,
'title': title,
'path': 'path',
'enabled': enabled
})
DB.jsonSave(data, 'items')
self.title.clear()
self.id.clear()
self.status.setChecked(False)
self.listitems.addItem(title)
# self.load()
I also recommend that if the data is going to be large it is not appropriate to save it in a json since it will see a great latency in the reading and writing of the data, the appropriate thing for those cases is to use a database, for example to use sqlite.

Building a server and client with xmlrpc in python

I'm trying to build a client and a server using xmlrpc in python, I HAVE to use a class named FunctionWrapper which has a method and the client use it, the method's name is sendMessage_wrapper(self, message), and the server is declared in another class, I'm trying to register the method in the server but when i call the method from de client I raise and error, can you help me, please?

def sendMessage(self,message):
self.proxy.sendMessage_wrapper(message)
a = MyApiClient()
a.sendMessage("Hi")
a.sendMessage("WORKING")

self.server.register_instance(self.wrapper)
print("Running")
self.server.serve_forever()
class FunctionWrapper:
def __init__(self):
self.message = None

Using asyncio to read the output of a serial port

I have been doing some port-reading for work, and I need to know if I should use asyncIO to read the data that comes in from this port.
Here's some details about the way in which the system is constructed.
Multiple sensors are being read at the same time and might produce output that goes in at the same time. (all data comes in through a probee ZU10 connected to a usb port) All data must be timestamped as soon as it comes in.
The data is supposed to be processed and then sent to a django webapp through a REST API.
The thing Is, it's really important not to lose any data, I'm asking about this because I believe there must be an easier way to do this than the one I'm thinking of.
The way I want the data to come in is through an asyncronous process that takes in the data into a queue and timestamps it, this way there is no way in which loss of data is present, and timestamping may be no more than a few fractions of a second off, which is not a problem.
If anyone has got any ideas I would be thankful for them
Here's the code I'm using to open the port, take the data in and what I've got so far on the actually reading the meaningful data.
Here's the reading part:
import serial #for port opening
import sys #for exceptions
#
#configure the serial connections (the parameters differs on the device you are connecting to)
class Serializer:
def __init__(self, port, baudrate=9600, timeout=.1):
self.port = serial.Serial(port = port, baudrate=baudrate,
timeout=timeout, writeTimeout=timeout)
def open(self):
''' Abre Puerto Serial'''
self.port.open()
def close(self):
''' Cierra Puerto Serial'''
self.port.close()
def send(self, msg):
''' envía mensaje a dispositivo serial'''
self.port.write(msg)
def recv(self):
''' lee salidas del dispositivo serial '''
return self.port.readline()
PORT = '/dev/ttyUSB0' #Esto puede necesitar cambiarse
# test main class made for testing
def main():
test_port = Serializer(port = PORT)
while True:
print(test_port.recv())
if __name__ == "__main__":
main()
And a bit of what I'm going to be using to filter out the meaningful reads (bear with it, it might be full of awful errors and maybe a terrible RegEx):
import re
from Lector import ChecaPuertos
from Lector import entrada
patterns = [r'^{5}[0-9],2[0-9a-fA-F] $'] #pattern list
class IterPat:
def __init__(self, lect, pat = patterns):
self.pat = pat # lista de patrones posibles para sensores
self.lect = lect # lectura siendo analizada
self.patLen = len(pat) #Largo de patrones
def __iter__(self):
self.iteracion = 0 #crea la variable a iterar.
def __next__(self):
'''
Primero revisa si ya pasamos por todas las iteraciones posibles
luego revisa si la iteración es la que pensabamos, de ser así regresa una
tupla con el patrón correspondiente, y la lectura
de otra forma para el valor de ser mostrado
'''
pattern = re.compile(self.pat[self.iteracion])
comp = pattern.match(self.lect)
if comp == True:
re_value = (self.pattern, self.lect)
return re_value
else:
self.iteración += 1
def main():
puerto = ChecaPuertos.serial_ports()
serial = entrada.Serializer(port = puerto[0])
if serial != open:
serial.open()
while True:
iter = IterPat()
#This is incomplete right here.

I am using asyncio to read/write a serial port with pyserial. I am having my device on the other end of the serial connection write a single byte when it is ready to receive a payload. Asyncio watches for that byte then sends the payload. It looks something like this:
serial_f = serial.Serial(port=dev, baudrate=BAUDRATE, timeout=2)
def write_serial():
status = serial_f.read(1)
serial_f.write(buffer)
loop = asyncio.get_event_loop()
loop.add_reader(serial_f.fileno(), write_serial)
