rodos 0.1.1

rodos middleware in python

This is a port of the rodos middleware to Python

RODOS is dependable real-time operating system used in satellites see rodos gitlab. The rodos middleware Python package was created to facilitate the development of PC software, that connects to a remote microcontroller. E.g. debugging embedded applications, displaying data, easier development in python instead of c++. It is writte in pure python dependent on pyserial and the operating system's UDP/rfcomm(bluetooth) stack

install the package with pip install rodos. Here is an example how to use in conjunction with the struct package, that comes handy for parsing data

#!/bin/python3
import time
import struct

import rodos

# from rodos import *

def topicHandler(data):
    try:
        unpacked = struct.unpack("qI4b", data)
        print("timeNow = ", unpacked[0])
        print("msgIndex = ", unpacked[1])
    except Exception as e:
        print(e)
        print(data)


luart = rodos.LinkinterfaceUART(path="/dev/rfcomm2")
gwUart = rodos.Gateway(luart)
gwUart.run()

linux2rodos = rodos.Topic(1002)
rodos2linux = rodos.Topic(1003)

rodos2linux.addSubscriber(topicHandler) # <<<<<< register callback

cnt = 0
while True:
    cnt += 1
    time.sleep(1)
