Sending data from MATLAB(Simulink) to Vizard
Hello,
I am trying to send data as packets of doubles in little endian format from MATLAB(Simulink) to Vizard. Since MATLAB is non-python interface, I am using code give on the forum and it is: from __future__ import print_function import viz viz.go() import vizact import socket log=open("new.txt","w") print("Hi there",file=log) #The maximum amount of data to receive at a time MAX_DATA_SIZE = 1024 #The port to send/receive data on PORT = 5600 #Get the name of this computer COMPUTER_NAME = socket.gethostname() #Get the IP address of this computer COMPUTER_IP_ADDRESS = socket.gethostbyname('localhost') #Create a socket to send data over #OutSocket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) #OutSocket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) #Create a socket to receive data from InSocket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) InSocket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) InSocket.bind(('192.168.1.2', PORT)) InSocket.setblocking(0) #def SendData(data): #OutSocket.sendto(data,(COMPUTER_IP_ADDRESS,PORT)) def ReceiveData(): try: return InSocket.recv(MAX_DATA_SIZE) except socket.error: #Insert error handling code here print("Error has occured",file=log) #vizact.onkeydown(' ',SendData,'hello there') def CheckSocket(): #Try to receive data from socket data = ReceiveData() if data: print (data,file=log) else: print("Data not received",file=log) vizact.ontimer(0,CheckSocket) I have removed data sending part by making it comment and trying to get data in file so that I can analyse(One more reason is that when I write simple print, I am getting nothing in Vizard). I am not understanding second line in socket creation for receiving data and also not getting any output. I tried to send data from MATLAB to MATLAB and its working but with Vizard it is giving problem. Please suggest appropriate corrections in code. Thanks:) |
