Test for making Arduino control panel

Hello,

I am making a control panel with buttons connected to an Arduino

I looked at this site : ckcnc.wordpress.com/2011/01/08/simple-emc-arduino-howto/

To try, I made a hall for connection "test"

On the Arduino, I have a button that send to the serial port the letter a
Another button sending the letter b

In the Arduino serial port, the value is sent

In my hallmeter pine arduino.test does not change?

My sketch Arduino
const int BoutonOn = 2; //le bouton est connecté à la broche 2 de la carte Adruino
const int BoutonOff = 3; //le bouton est connecté à la broche 3 de la carte Adruino
const int LedOn = 13; //la LED à la broche 13

int etatBoutonOn; //variable qui enregistre l'état du bouton
int etatBoutonOff; //variable qui enregistre l'état du bouton
boolean Marche;

void setup()
{
   pinMode(LedOn, OUTPUT); //la led est une sortie
   pinMode(BoutonOn, INPUT); //le bouton est une entrée
   digitalWrite(BoutonOn,HIGH); // active pull-up interne
   pinMode(BoutonOff, INPUT); //le bouton est une entrée
   digitalWrite(BoutonOff,HIGH); // active pull-up interne
   etatBoutonOn = LOW;
   etatBoutonOff = LOW;
   Marche =  false;
   digitalWrite(LedOn,LOW);
  
  Serial.begin(9600);
}

void loop()
{
   etatBoutonOn = digitalRead(BoutonOn); 
   etatBoutonOff = digitalRead(BoutonOff); 
  
   if(etatBoutonOn == HIGH)//test si le bouton a un niveau logique bas
   {
     delay (200) ; // ne pas relire tout de suite l'état, protection anti-rebond  
     Marche = true;
   }

    if(etatBoutonOff == HIGH) //est si le bouton a un niveau logique bas
   {
     delay (200) ; // ne pas relire tout de suite l'état, protection anti-rebond  
     Marche = false;
   }


if (Marche == true)
{
  digitalWrite(LedOn,HIGH); //la LED est allumée
  Serial.println("a");
}

else
{
digitalWrite(LedOn,LOW); //le bouton est appuyé, la LED reste éteinte
Serial.println("b");
}

}

My python script
#!/usr/bin/python


import serial
import hal
import sys
import time

PORT = "/dev/ttyACM0"
ser = serial.Serial(PORT, 9600, timeout=2)

#Now we create the HAL component and its pins
c = hal.component("arduino")
c.newpin("test",hal.HAL_BIT,hal.HAL_IN)
c.ready()

try:
  while 1:
    time.sleep(1)
    while ser.inWaiting():
      key = ser.readline()  


      if(key == "a"):
          c['test'] = 1
      if(key == "b"):
          c['test'] = 0



except KeyboardInterrupt:
#    ser.write("-P;");
    raise SystemExit

My custompostgui.hal
# Inclure vos commandes HAL personnalisées ici
# Les commandes contenues dans ce fichier seront lancées après quel'interface graphique AXIS (PyVCP inclus) aura démarré.

sets spindle-at-speed true

#First we load the Python user module named /user/bin/simple_arduino with the name 'arduino'
loadusr -Wn arduino Nouveau

 
#Map the machine on/off state to the arduino
net test arduino.test

Have you seen emergent.unpythonic.net/01198594294 ?

Hello Andy,

I saw but I try to understand the system with a simple code.

I do not understand why it does not work?
