The last version of Display_lib_RPI (V1.3.0) which used the bcm2835 library as a dependency low level interface
is in releases and can still be downloaded and used. Version 1.3.0 will NOT work on raspberry pi 5 and uses direct register access.
It is generally speaking faster than the lgpio.

The lgpio library works with linux device drivers like spidev.
Using Linux device drivers allow the library to work on Raspberry 5 as well as other linux computers that lgpio can be installed on
