Python is now widely used, especially various support packages, which are extremely rich in content and powerful. In embedded systems now, the programming of single-chip microcomputers is still dominated by C/C++. The goal of this project is to build a python development package for the microcontroller. The project supports common educational circuit boards, such as Arduino, and is also convenient for users to transplant to their own developed circuit boards. Unlike MicroPython, which transplants the python compiler to the microcontroller, the python program of this project runs on the PC side. First, the corresponding circuit board interface package is referenced. Through wireless (Bluetooth/WIFI) or wired (USB/serial port), directly call the hardware resources of the circuit board and operate the IO port. The advantage of this is that python programs can be developed on the PC side, and all Python support packages can be freely referenced. The hardware circuit board is also used as a support package for python, Direct reference, that is, you can operate hardware resources, is very convenient. The disadvantage is that the single-chip microcomputer cannot be separated from the PC to complete the task independently, and the PC remote control is required to complete the task.
