# Makefile for Arduino based scketches

#
# This Makefile uses the arduino-cli, the Arduino command line interface
# and has been designed and tested to run on Linux, not on Windows.
# Probably it will run on a Mac, but it has not been tested.
#
# Please note that:
#
#   1. each sketch must reside in his own folder with this Makefile
#
#   2. the main make targets are:
#      - all     compiles and upload
#      - compile compiles only
#      - upload  upload via serial port, compile if the binary file is
#                not available
#      - ota     upload Over The Air, automatically find the device
#                IP address using the IOT_NAME (device hostname)
#      - clean   clean the build directory
#      - find    find OTA updatable devices on the local subnet
#      - requirements it the file "requirements.txt" exists it will
#                     install the libraries listed in this file
#
#      default is "all"
#
#   3. it gets the name of the sketch using the wildcard make command;
#      the name is *.ino; this means that you must have ONLY a file
#      with .ino extension, otherwise this makefile will break.  This
#      also means that you can use this Makefile, almost unmodified,
#      for any sketch as long as you keep a single .ino file in each
#      folder
#
#   4. you can split your project in multiple files, if you wish,
#      using a single .ino file and multiple .h files, that you can
#      include in the .ino file with an '#include "myfile.h"'
#      directive
#
# Optionally some environment variables can be set:
#
#   FQBN        Fully Qualified Board Name; if not set in the environment
#               it will be assigned a value in this makefile
#
#   SERIAL_DEV  Serial device to upload the sketch; if not set in the
#               environment it will be assigned:
#               /dev/ttyUSB0   if it exists, or
#               /dev/ttyACM0   if it exists, or
#               unknown
#
#   IOT_NAME    Name of the IOT device; if not set in the environment
#               it will be assigned a value in this makefile. This is
#               very useful for OTA update, the device will be searched
#               on the local subnet using this name
#
#   OTA_PORT    Port used by OTA update; if not set in the environment
#               it will be assigned the default value of 8266 in this
#               makefile
#
#   OTA_PASS    Password used for OTA update; if not set in the environment
#               it will be assigned the default value of an empty string
#
#   V           verbose flag; can be 0 (quiet) or 1 (verbose); if not set
#               in the environment it will be assigned a default value
#               in this makefile
