Named in the spirit of gen_mpy.py from LVGL's original lv_binding_micropython generator — gen_binding.py is a ground-up, multi-target rewrite, not a fork, so it doesn't share that file's name.

Downstream Binding Consumers

lvgl-micropython

Consumes generated/lvgl_micropython.c for MicroPython MCU firmware builds.

lvgl-circuitpython

Consumes generated/lvgl_circuitpython.{c,h} for CircuitPython out-of-tree native extensions.

lvgl-python

Consumes generated/lvgl_python.c for CPython binary wheels and Pyodide WebAssembly packages.
