Is there a 16x2 i2c LCD python module ?

[chicag...@gmail.com]

This is something that I thought I would find easily. I have a 12c backpack that connects to a 16x2 LCD panel. 

https://www.adafruit.com/product/292

I thought for sure I could download Python code to use it but I guess not.

I installed this from adafruit

pip3 install adafruit-circuitpython-charlcd

and in the example the first line 

import board failed. 

import board
import digitalio
import adafruit_character_lcd.character_lcd as character_lcd

So is panel or lib out there that works with the beaglebone black via i2c ?

That package is primarily to be used with their version of
"circuitpython" which runs on microcontroller boards (Adafruit Metro M4,
for example) that don't have an operating system.

Supported boards are at
https://circuitpython.org/downloads

However... The circuitpython documentation has a section on using it on
a Raspberry-Pi... Using an interface package to translate the CircuitPython
hardware I/O to Linux compatible operations.

You will probably have to follow that and edit the needed files to map the
I/O to the Beagle equivalent. (Actually, it looks like Beaglebone Black and
Pocket Beagle definitions were added April 2, so you might get away with
just installing that library)
