# Makefile for esp-link - https://github.com/jeelabs/esp-link
|

#
|
|
# Start by setting the directories for the toolchain a few lines down
|
|
# the default target will build the firmware images
|
|
# `make flash` will flash the esp serially
|
|
# `make wiflash` will flash the esp over wifi

|

# `ESP_HOSTNAME=my.esp.example.com make wiflash` is an easy way to override a variable

|
|
# This could speed up the downloading of these files, but might break compatibility with older
|
|
# web browsers not supporting gzip encoding because Accept-Encoding is simply ignored.
|
|
# Enable this option if you have large static files to serve (for e.g. JQuery, Twitter bootstrap)
|
|
# By default only js, css and html files are compressed using heatshrink.
|
|
# If you have text based static files with different extensions what you want to serve compressed
|

# then you will need to add the extension to the following places:
|
|
# - Add the extension to this Makefile at the webpages.espfs target to the find command
|
|
# - Add the extension to the gzippedFileTypes array in the user/httpd.c file
|
|
#
|
|
# Adding JPG or PNG files (and any other compressed formats) is not recommended, because GZIP
