I just finished a demo which is to provide an easy way to control hardware resources of A sample. The communication between PC and A sample is UART. The PC software is written by Python.
Python can implement features very soon and has a rich libraries. I used two libraries, one is console-menu, and another is pyserial.
pip install console-menu
https://pypi.org/project/console-menu/
pip install pyserial
https://pypi.org/project/pyserial/
When startup, a prompt input will display:
Input the COM number what you want. And then the operation window will display.
You can select the menu for future operation, e.g. Alarm,
I attached the source code here for your reference.
