Example of python getting GY-85 9-axis module information in Raspberry Pi

The content of this article is Raspberry Pi python get GY-85 nine axis module information example, here using Python curses package development cli window program, used to refresh the sensor reading in real time, see the code first

GY-85.py:

The code is as follows:
