1/30/2019 0 Comments Asynchronous Serial Port PythonI'd like to read from two (or more) serial ports (/dev/ttyUSB0 etc) at the same time in python on Linux. I want to read complete lines from each port (whichever has data) and process the results in the order received (without race conditions). As a simple example could just write the lines to a single merged file. I assume the way to do this is based on pyserial, but I can't quite figure out how to do it. Pyserial has non-blocking reads using and using. Asyncio is marked as experimental. I assume there wouldn't be any race conditions if the processing is done in asyncio.Protocol.data_received(). In the case of threads, the processing would probably have to be protected by a mutex. Perhaps this can also be done not in pyserial. Make.video.er 3.7.1 offline er. The two serial ports can be opened as files and then read from when data is available using select(). Free cnc software downloads. Asynchronous Python. Await the Future. Asynchronous programming in python has become more and more popular lately. There are many different libraries in python for doing asynchronous programming.
