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

PS: The i2c address ix 0x3C

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.

 sudo python Pld.py

Note: you can get the sample python file from github also;

git clone https://github.com/geekworm-com/T208

FAQ

A: Found some error

Q: 1. check your python version with command 'sudo python -v'

Hi, is there any way to obtain the actual continuous value of current flowing into the T208 and out of it to the Jetson Nano?

Hi,

you can use the python 'Pld.py' to check the input charge. Refer to step 7 above
