# ESPurna module memory analyser
# xose.perez@gmail.com
#
# Rewritten for python-3 by Maxim Prokhorov
# prokhorov.max@outlook.com
#
# Based on:
# https://github.com/letscontrolit/ESPEasy/blob/mega/memanalyzer.py
# by psy0rz <edwin@datux.nl>
# https://raw.githubusercontent.com/SmingHub/Sming/develop/tools/memanalyzer.py

#
# When using Windows with non-default installation at the C:\.platformio,
# you would need to specify toolchain path manually. For example:
#
# $ py -3 scripts\memanalyzer.py --toolchain-prefix C:\.platformio\packages\toolchain-xtensa\bin\xtensa-lx106-elf- <args>
#
# You could also change the path to platformio binary in a similar fashion:
# $ py -3 scripts\memanalyzer.py --platformio-prefix C:\Users\Max\platformio-penv\Scripts\
