#
# 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
# `VERBOSE=1 make ...` will print debug info
# `ESP_HOSTNAME=my.esp.example.com make wiflash` is an easy way to override a variable
#
# optional local configuration file
-include local.conf
# Makefile heavily adapted to esp-link and wireless flashing by Thorsten von Eicken
# Lots of work, in particular to support windows, by brunnels
# Original from esphttpd and others...
# VERBOSE=1

# --------------- toolchain configuration ---------------

# Base directory for the compiler. Needs a / at the end.
# Typically you'll install https://github.com/pfalcon/esp-open-sdk
XTENSA_TOOLS_ROOT ?= $(abspath ../esp-open-sdk/xtensa-lx106-elf/bin)/

# Base directory of the ESP8266 SDK package, absolute
# Typically you'll download from Espressif's BBS, http://bbs.espressif.com/viewforum.php?f=5
SDK_BASE	?= $(abspath ../esp_iot_sdk_v1.5.0)

# Esptool.py path and port, only used for 1-time serial flashing
# Typically you'll use https://github.com/themadinventor/esptool
# Windows users use the com port i.e: ESPPORT ?= com3
ESPTOOL		?= $(abspath ../esp-open-sdk/esptool/esptool.py)
ESPPORT		?= /dev/ttyUSB0
ESPBAUD		?= 460800

# The Wifi station configuration can be hard-coded here, which makes esp-link come up in STA+AP
# mode trying to connect to the specified AP *only* if the flash wireless settings are empty!
# This happens on a full serial flash and avoids having to hunt for the AP...
# STA_SSID ?= 
# STA_PASS ?= 

# hostname or IP address for wifi flashing
ESP_HOSTNAME        ?= esp-link

# --------------- chipset configuration   ---------------

# Pick your flash size: "512KB", "1MB", or "4MB"
FLASH_SIZE ?= 4MB

# The pin assignments below are used when the settings in flash are invalid, they
# can be changed via the web interface
# GPIO pin used to reset attached microcontroller, acative low
MCU_RESET_PIN       ?= 12
# GPIO pin used with reset to reprogram MCU (ISP=in-system-programming, unused with AVRs), active low
MCU_ISP_PIN         ?= 13
# GPIO pin used for "connectivity" LED, active low
LED_CONN_PIN        ?= 0
# GPIO pin used for "serial activity" LED, active low
LED_SERIAL_PIN      ?= 14

# --------------- esp-link config options ---------------

# If CHANGE_TO_STA is set to "yes" the esp-link module will switch to station mode
# once successfully connected to an access point. Else it will stay in AP+STA mode.

CHANGE_TO_STA ?= yes

# Optional Modules
MODULES ?= mqtt rest syslog

# --------------- esphttpd config options ---------------

# If GZIP_COMPRESSION is set to "yes" then the static css, js, and html files will be compressed
# with gzip before added to the espfs image and will be served with gzip Content-Encoding header.
# 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)
# 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
# compression does not work effectively on compressed files.

#Static gzipping is disabled by default.
GZIP_COMPRESSION ?= yes

# If COMPRESS_W_HTMLCOMPRESSOR is set to "yes" then the static css and js files will be compressed with
# htmlcompressor and yui-compressor. This option works only when GZIP_COMPRESSION is set to "yes".
# https://code.google.com/p/htmlcompressor/#For_Non-Java_Projects
# http://yui.github.io/yuicompressor/
# enabled by default.
COMPRESS_W_HTMLCOMPRESSOR ?= yes
HTML_COMPRESSOR ?= htmlcompressor-1.5.3.jar
YUI_COMPRESSOR ?= yuicompressor-2.4.8.jar
