# Makefile for ESP8266 projects
# based on: https://github.com/esp8266/source-code-examples
# - modified by patrikhl
#
# Thanks to:
# - zarya
# - Jeroen Domburg (Sprite_tm)
# - Christian Klippel (mamalala)
# - Tommie Gannert (tommie)
#
# Changelog:
# - 2014-10-06: Changed the variables to include the header file directory
# - 2014-10-06: Added global var for the Xtensa tool root
# - 2014-11-23: Updated for SDK 0.9.3
# - 2014-12-25: Replaced esptool by esptool.py
# - 2017-05-18: Added support for compiling .S files
# Split makefile into two (for use with docker)
# Added flavor opton (debug / release)
# - debug will automatically compile esp-gdbstub
# Output directors to store intermediate compiled files
# relative to the project directory
