Installation

From PyPI

You can install RPLCD directly from PyPI using pip:

$ sudo pip install RPLCD

If you want to use I²C, you also either the smbus or smbus2 library:

$ sudo apt install python-smbus
or
$ sudo pip install smbus2

RPLCD will first try to use smbus if available and if not, fall back to smbus2.

If you want to use pigpio, the easiest way is to install the library via your packet manager (select the Python version you need):

$ sudo apt-get install pigpio python-pigpio python3-pigpio

Manual Installation

You can also install the library manually without pip. Either just copy the scripts to your working directory and import them, or download the repository and run python setup.py install to install it into your Python package directory.
