SerialComPython

Serial Communication Python Class. CUI and GUI both are available.

Strong Points

• Using a thread, TX and RX both are available at the same time.
• Execute serial.close() and disconnect safely.

serialcompy (Python Code)

Serial Communication Python Class.

Imports

• time: Standard library
• threading: Standard library
• serial (pySerial): Third-Party library (pip install pyserial)

main_gui (Python Code)

1. Startup window.
   

2. Select a comport from the combobox. If you connect a device after the startup, push "Reload" button and check the combobox again.
   

3. After input a baudrate, push "Open" button. If the "Baudrate" entry is empty, the rate is 9600 bps by default or the last bps you open the port.
   

4. Input string to "Text" entry and push "Send" button. "TX" listbox is a sending history and "RX" listbox is a receiving history. Pushing "TX Export" button or "RX Export" button, you can save these histories as a text file.
   

5. To disconnect, push "Close" button.
   

main_cui (Python Code)

1. Select a comport.
2. Input "yes", "y" or "no", "n".
3. Serial communication starts.
4. To disconnect, input Ctrl+C.
   

SerialCom (Arduino Code)

• 9600 bps serial communication
• Once get a string, send it.
