[Lino Amorim]

Hello!
I am trying drive a simple two rows LCD screen, using
Omega2Pro with I2C protocol.
So far, I am only being able to turn off de LCD screen backlight...
I am using de same set up in the pictures of documetation...

My input and outputs:
I tried: git clone https://github.com/Fires04/OnionOmega-I2C-LCD
Output: fatal: destination path 'OnionOmega-I2C-LCD' already exists and is not an empty directory.
I tried: cd fireonion_i2c_lcd/src
Output: -ash: cd: can't cd to fireonion_i2c_lcd/src: No such file or directory
I tried: python lcd.py --help
Output: python: can't open file 'lcd.py': [Errno 2] No such file or directory

Others outputs:
Package git (2.16.6-1) installed in root is up to date.
Package git-http (2.16.6-1) installed in root is up to date.
Package python (2.7.17-1) installed in root is up to date.
Package pyOnionI2C (0.9-1) installed in root is up to date.

I am only trying write something in a LCD screen...
Any help?...
Thank you!
