Rock64-I2C-LCD-Stats

This is a project to create a python script that will work with infomration from RPi-Monitor to display the real time stats to a I2C LCD screen connected to a Rock64. This is currently being used with a 16x2 I2C LCD.

Stats and Metrics that can be displayed

The following list is of all the stats that RPi-Monitor collects for the Rock64. These stats are part of the python script that can be configured to display then accordingly.
