Question

我有一个程序写入处理（处理实时音频）和用python编写的程序（调用gatttool通过蓝牙低功耗与外设通话）。有没有一种直接的方法将值从处理发送到python？我应该创建一个串行连接并以这种方式传递字节吗？

请记住，它们在同一台计算机上运行，最好使用套接字在Python端创建服务器，在处理端创建客户端，并将数据从客户端发送到服务器。 Python服务器将等待来自Processing客户端的连接，并在收到数据后使用它们。

您可以在网络上找到示例等，但以下是Proccessing和Python文档提供的示例：

import processing.net.*; 
Client myClient;

void setup() { 
  size(200, 200); 
  /* Connect to the local machine at port 5204
   *  (or whichever port you choose to run the
   *  server on).
   * This example will not run if you haven't
   *  previously started a server on this port.
   */
  myClient = new Client(this, "127.0.0.1", 5204); 
} 

void draw() { 
  myClient.write("Paging Python!"); // send whatever you need to send here
}

Python server:

# Echo server program
import socket

HOST = ''                 # Symbolic name meaning all available interfaces
PORT = 50007              # Arbitrary non-privileged port
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((HOST, PORT))
s.listen(1)
conn, addr = s.accept()
print('Connected by', addr)
while True:
    data = conn.recv(1024)
    if not data: break
    print(data) # Paging Python!
    # do whatever you need to do with the data
conn.close()
# optionally put a loop here so that you start 
# listening again after the connection closes

在处理草图和python程序之间进行通信？
