We test the following step base the Jetson nano image (ubuntu 18.04 LTS)

1. Update software source on Ubuntu, refer to Update software source on Ubuntu

NOTE: You must connect the internet via Ethernet or Wireless USB adapter before software update.

2. To install pip for Python 3 on Ubuntu, run the following commands as root or sudo user in your terminal:

sudo apt-get update
sudo apt-get install python-pip  

3. To install Jetson GPIO library:

sudo pip install Jetson.GPIO

4. To install I2C dev library

sudo apt-get install libi2c-dev i2c-tools
pip install smbus

5. To check what i2c devices connected (This is very important!!)

sudo i2cdetect -y -r 1
#(T208 used the I2C address 0x36)

6. To install Nano editor on Ubuntu

sudo apt-get install nano 

7. Download the sample python file (File:Bat.py) for i2c battery voltage & percentage reading, then run the following command to test it.

 sudo python Bat.py

8. Download the sample python file (File:Pld.py) for AC power loss / power adapter failure detection, then run the following command to test it.
