Python Serial Read Write Serial Device While

Data ser.read(size5) to read one line from serial device. Data ser.readline() to read the data from serial device while something is being written over it.

However, I have the issue that my python script will throw an error because the port is already open and I am not able to write to the COM port.Is there some other way to do write from a python script and read that information into my PSOC? For my application, I have a script in Python that outputs coordinates. Theoretically, I thought that if my python script wrote to a Com port, and my UART was connected to that same COM port, I'd be able to read information in. For testing, currently just trying to send the letter 'a'.)Ser = serial.Serial('COM4', 115200, timeout=1)Then within PSOC file, I have a UART that is able to read and write from a Com port too. (Below is what I added to my python script. It would be nice to make it detect the beginning of the 16 byte sample.I'm currently trying to open a Serial com port in my python script, and write to that com port. When I suddenly start the Python script sometimes it starts in the middle of data stream.

From the Python script, you can access the python interface COM port.If the issue is the port access getting denied that it is because you might have the port already open in another software like a terminal. Connect the python interface pins to either a USB-Serial interface or another kit's UART pins (could be any kit that supports USB-UART interface - make sure the primary device in that kit does not load the UART lines). Connect the printf interface to P5.0/1 and the Python interface to another port pin.3. Use two UART blocks inside PSoC - one for Python interface and another for terminal/printf interface2.
