Has anyone successfully used the luma.core library for an LCD driven by a Hitachi HD44780 controlled by a Pi? I have a Vilros LCD1602A which I have been able to control using a localized version of Andy Crook's (...) code for LCD 16x2 Display for Pi Pico. However, when I've tried to use the luma libaries my display doesn't initialize. If I run one of my scripts which initializes the display and then run a script from the luma examples it works since the display is already initialized. I've tried fiddling with the delays and the order of commands in <path to venvs>/luma-env/lib/python3.11/site-packages/luma/lcd/device.py where the initialization should be made, but with no joy. (I know the commands are run since I stuck some print statements in the code to see if they were being called.)
