            Spread the result of GPS in to separate variables.

            You should just open the file once, not every time through the loop. You can use f.flush() to flush the line to the file immediately.

If need the response from device, should use read_until(), not sure weather this is a good way, please let me know if you have any suggestions. Anyway, the class i make, can read the omron PLC by giving different params, hope it can help someone.

            You can use the working Test Vectors from the GlobalPlatform library and test if your executed crypto logic is really working. It could also be that your card is using some key derivation scheme, i.e. the keys you are using cannot be used directly.

            Can't stop thread at all (unless I cause an exception)
            Asked 2022-Feb-17 at 10:42

            So I am working on a GUI (PyQt5) and I am multi-threading to be able to do data acquisition and real-time plotting concurrently.

            Long story short, all works fine apart from stopping the thread that handles the data acquisition, which loops continuously and calls PySerial to read the com port. When a button on the GUI is pressed, I want to break the while loop within the thread so as to stop reading the com port and allow the com port to be closed safely.

            Currently, none of the methods I have tried manage to gracefully exit the while loop inside the thread, which causes all kinds of errors with the PySerial library and the closed com port/ attempted reading in the thread. Here is what I have tried:

            • Using a class variable (self.serial_flag) and changing its state when the button is pressed. The thread loop then looks like this: while self.serial_flag:
            • Using a global variable (serial_flag = False at top of the script). Defining global serial_flag at the top of the threaded function and same condition: while serial_flag:
            • Using a shared memory variable: from multiprocessing import Value, then defining serial_flag = Value('i', 0) then in the loop checking while serial_flag.value == 0:
            • Using threading.Event to set an event and use that as a break condition. Defining: serial_flag = threading.Event() and inside the thread while loop: if serial_flag.is_set(): break

            None of these seem to work in breaking the while loop and I promise I have done my homework in researching solutions for this type of thing - I feel like there is something basic that I am doing wrong with my multithreading application. Here are the parts of the GUI that call/ deal with the thread (with my latest attempt using threading.Event):

            The problem occurs because you are closing the serial port without waiting for the thread to terminate. Although you set the event, that part of the code might not be reached, since reading from the serial port is still happening. When you close the serial port, an error in the serial library occurs.

            You should wait for the thread to terminate, then close the port, which you can do by adding

            Threading reading a serial port in Python (with a GUI)
            Asked 2022-Jan-19 at 18:19

            I want to trigger an event whenever there is data to be read from a serial port while running a GUI. The pySerial module apparently has experimental functionality for that, but it isn't particularly well documented (I couldn't find any useful examples in the API).

            Your main concern is to be thread safe, when You are updating GUI from another running Thread.
            To achieve this, we can use .after() method, which executes callback for any given tk widget.

            Another part of Your request is to use Threaded serial reader.
            This can be achieved by using ReaderThread accompanied with Protocol.

            You can pick two protocols:

            Here is working code example, with two protocols mentioned above, so You can pick which one suits You. Just remember, that all data coming from serial port are just raw bytes.

            pySerial problem: embedded controller stops echoing commands
            Asked 2022-Jan-05 at 23:37

            I'm trying to use pySerial running on an Ubuntu host to automate testing of an embedded controller. I can enter commands in a terminal window (e.g., PuTTY) and get responses from the EC all day long. However, when I try using a pySerial program to do the same thing, the EC stops echoing the commands after some time, right in the middle of echoing a command. From that point forward, the EC stops responding to the program, including not sending results from the command that was interrupted.

            If I terminate the program and try to connect to the EC with a terminal again, the EC is unresponsive. If an external event happens that causes the EC to write output to the terminal, that information is displayed correctly. The problem persists until I reboot the EC - which also erases any logs of what was happening on the EC when the problem occurred. (The logs are only accessible through the serial port...)

            It appears that something pySerial is doing causes the EC's input processing to stop. I tried typing Ctrl-Q (XON) hoping there was some software flow control going on that wasn't obvious, but that didn't make a difference. I've tried sending alternating commands in the program, sending blank lines between sending commands, inserting delays between when the commands are sent - but it dies, every time, after processing a few commands.

            This is the script I'm currently using:

            ANSWER

            Answered 2022-Jan-05 at 23:37

            It appears the testing procedure was actually in error: Following one of my colleague's example, I typed the "battery current" command into the terminal, got a response, then used the up-arrow key to re-run the command - which seems to work all day long.

            However, that's not the same test: Up-arrow (which retrieves the last command from the EC's history) followed by is not the same as repeatedly typing the command and sending it.

            When I repeatedly pasted the command into the terminal window as quickly as I could, the EC failed exactly the same way as did sending the commands using pySerial: The failure is internal to the EC, not something different pySerial was doing on the communication line.

            Interface Arduino/RedBoard vibrator to Python
            Asked 2021-Dec-30 at 15:33

            I am trying to interface my SparkFun Qwiic Haptic Driver - DA7280 with Python3. My current set-up is as follows:

            PC -USB to micro-USB-> SparkFun RedBoard Qwiic -Qwiic Cable-> Haptic Driver

            I suspect at least part of the problem is that you are not clearing the contents of the read buffer, only checking if something is there. Serial.flush() i think that as of Arduino 1.00 (don't quote me on that) serial flush doesn't do anything to the incoming buffer.

            try adding a var = Serial.read() in before your hapDrive.setVibrate(25); and see if that changes the functionality.

            I also HEAVILY recommend interrupts for serial. There's a serial event example that's really comprehensive (although i seem to remember that's not actually interrupt driven in the classical microcontroller sense, but it's close enough!)
