Question

我想将数据从Simulink模型（实时运行）发送到Python脚本（也是实时运行。我使用的是Simulink内置的＆＃34; UDP Send＆＃34;阻止如果simulink发送一个常量＆＃34; 10＆＃34;，我得到（10.0，）的输出。但我想要10个。

import sys, struct
from socket import *

SIZE = 1024      # packet size

hostName = gethostbyname('0.0.0.0')

mySocket  = socket(AF_INET,SOCK_DGRAM)
mySocket.bind((hostName,18726))

repeat = True
if repeat:
    (data,addr) = mySocket.recvfrom(SIZE)
    data = struct.unpack('d',data)
    print data

Answer 1

 import sys, struct
 from socket import *

 SIZE = 1024      # packet size

 hostName = gethostbyname('0.0.0.0')

 mySocket  = socket(AF_INET,SOCK_DGRAM)
 mySocket.bind((hostName,18726))

 repeat = True
 if repeat:
    (data,addr) = mySocket.recvfrom(SIZE)
    data = struct.unpack('d',data)
    print (int)data[0]

通过udp从simulink块接收数据
