Arduino Restful Server

This example demonstrates how to use Fossa to control Arduino using HTTP requests. Example just blinks by LED when Fossa receives HTTP command, but it can be modified to execute any user-specific code.

At the moment this example supports Arduino Mega 2560 board (and compatible) with either W5100-based network shield (like Arduino Ethernet Shield) or CC3000-based WIFI Shield.

Build and run instructions:

###To run with Arduino Ethernet (W5100) shield:

  1. Add (Sketch->Add file...) the following files to sketch:
    • /fossa/fossa.h
    • /fossa/fossa.c
    • /fossa/platforms/arduino_ethernet_W5100/avrsupport.h
    • /fossa/platforms/arduino_ethernet_W5100/avrsupport.cpp
  2. Make board_ip and board_mac variables suitable for your network and board
  3. Uncomment line #include <Ethernet.h>
  4. Compile and flash sketch
  5. Run curl http://<board_ip/blink LED attached to PIN 13 will blink and board free memory size and board uptime will be displayed.

###To run with Adafruit WiFi (CC3000) shield:

  1. Add (Sketch->Add files...) the following files to sketch:
    • /fossa/fossa.h
    • /fossa/fossa.c
    • /fossa/platforms/arduino_ethernet_W5100/avrsupport.h
    • /fossa/platforms/arduino_ethernet_W5100/avrsupport.cpp
  2. Import Adafruit CC3000 library for fossa (select Sketch->Import Library...->Add library... and point /fossa/platforms/arduino_wifi_CC3000/adafruit_CC3000_lib_fossa folder)
  3. Make the following variables suitable for your network
    • board_ip
    • subnet_mask
    • gateway
    • dns
    • wlan_ssid
    • wlan_pwd
    • wlan_security
  4. Uncomment line #include <Adafruit_CC3000.h>
  5. Compile and flash sketch
  6. Run curl http://<board_ip/blink LED attached to PIN 13 will blink and board free memory size and board uptime will be displayed.
