IRC on an Arduino-powered GLCD

IRC on a GLCD!

I found this thing about making an IRC bot in Python, and thought: since I know how to send serial information from Python using pySerial and how to receive serial information on the Arduino as well as knowing how to output text on a GLCD, why not make an Arduino program that shows IRC text on a GLCD?

Basically, the IRC bot connects to a server and channel you choose, and it just stays in there, sending serial information to the Arduino. Using the GLCD library 3 beta, the Arduino simply prints each character received to a text area and checks for newlines.

The IRC bot isn’t that great (probably still needs a lot of work) but it gets the job done.

Source code available here and in the full post. Note that the Python script requires pySerial and Python 3.1.

Source code for Arduino:

#include 
#include "fonts/SystemFont5x7.h"       // system font

gText textArea = gText(textAreaFULL);

char charRead;

void setup() {
  GLCD.Init(INVERTED);
  GLCD.SelectFont(System5x7);
  GLCD.ClearScreen();
  
  textArea.DefineArea(textAreaFULL);
  textArea.SelectFont(System5x7, BLACK);
  textArea.ClearArea();
  
  Serial.begin(9600);
}

void loop() {
  if (Serial.available()) {
    charRead = char(Serial.read());
    if (charRead == '¥n') {
      textArea.println();
    }
    else
      textArea.print(charRead);
  }
}

Source code for Python (3.1). I included struct for another thing I was testing; you can probably just remove them:

import socket, serial, struct, os

def sendBytes(inputString):
    irc.send( bytes(inputString,ENCODING) )

def output(inputString):
    print(inputString, sep='')
    arduino.write(inputString.encode(ENCODING))

def getNick():
    return data.split('!')[0].replace(':', '')

def getMessage():
    return ':'.join(data.split(':')[2:]).replace('¥r¥n','¥n')

def say(string):
    sendBytes("PRIVMSG %s :%s¥r¥n" % (CHANNEL, string) )
    output(" %s" % (NICKNAME, string))

arduino = serial.Serial(SERIAL_PORT, 9600, timeout=5)

irc = socket.socket ( socket.AF_INET, socket.SOCK_STREAM )
irc.connect ( ( NETWORK, PORT ) )
irc.recv ( 4096 )
sendBytes("NICK %s¥r¥n" % NICKNAME)
sendBytes("USER %s %s %s :%s¥r¥n" % ¥
                 (USER, HOST_NAME, SERVER_NAME, REAL_NAME) )
sendBytes("JOIN %s¥r¥n" % CHANNEL)
say(JOIN_MESSAGE)

while True:
    data = str(irc.recv ( 4096 ),ENCODING)
    print(data)
    if data.find ("PING") != -1:
        sendBytes("PONG "+ data.split()[1] + "¥r¥n" )
    elif data.find("PRIVMSG") != -1:
        destination = ''.join(data.split(':')[:2]).split(' ')[-2]
        if destination == NICKNAME:

        if getMessage().find("!quit") != -1 and getNick() == OWNER:
            sendBytes("QUIT %s¥r¥n" % QUIT_MESSAGE)
            arduino.close()
            os._exit(99)
