# Create frozen modules structure for MicroPython.
|
|
#
|
|
# Usage:
|
|
#
|
|
# Have a directory with modules to be frozen (only modules, not packages
|
|
# supported so far):
|
|
#
|
|
# frozen/foo.py
|
|
# frozen/bar.py
|
|
#
|
|
# Run script, passing path to the directory above:
|
|
#
|
|
# ./make-frozen.py frozen > frozen.c
|
|
#
|
|
# Include frozen.c in your build, having defined MICROPY_MODULE_FROZEN_STR in
|
|
# config.
