# Arduino Restful Client
|
||||
|
||||
This example demonstrates how to use [Mongoose](https://www.cesanta.com/mongoose) to send HTTP commands from Arduino.
|
||||
|
||||
Example sends free memory size and current board uptime, but it can be modified to send any user-specific data.
|
||||
|
||||
At the moment this example supports [Arduino Mega 2560](http://arduino.cc/en/Main/ArduinoBoardMega2560) board (and compatible) with either W5100-based
|
||||
network shield (like [Arduino Ethernet Shield](http://arduino.cc/en/Main/ArduinoEthernetShield)) or [CC3000](http://www.ti.com/product/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:
|
||||
- /mongoose/mongoose.h
|
||||
- /mongoose/mongoose.c
|
||||
- /mongoose/platforms/arduino_ethernet_W5100/avrsupport.h
|
||||
- /mongoose/platforms/arduino_ethernet_W5100/avrsupport.cpp
|
||||
3. Buils and start (in console) /Users/alex/Projects/mongoose/examples/restful_server example
|
||||
4. Make `board_ip` and `board_mac` variables suitable for your network and board
|
||||
5. Change IP address in `s_target_address` variable to IP address of host running restful_server
|
||||
6. Uncomment line `#include <Ethernet.h>`
|
||||
7. Compile and flash sketch
|
||||
8. restful_server will start to show current uptime and free memory size (with 5 seconds interval)
|
||||
|
||||
###To run with Adafruit WiFi (CC3000) shield:
|
||||
1. Add (Sketch->Add files...) the following files to sketch:
|
||||
- /mongoose/mongoose.h
|
||||
- /mongoose/mongoose.c
|
||||
- /mongoose/platforms/arduino_ethernet_W5100/avrsupport.h
|
||||
- /mongoose/platforms/arduino_ethernet_W5100/avrsupport.cpp
|
||||
2. Import Adafruit CC3000 library for mongoose
|
||||
(select Sketch->Import Library...->Add library... and point
|
||||
/mongoose/platforms/arduino_wifi_CC3000/adafruit_CC3000_lib_mongoose folder)
|
||||
3. Buils and start (in console) /Users/alex/Projects/mongoose/examples/restful_server example
|
||||
4. Make the following variables suitable for your network
|
||||
- `board_ip`
|
||||
- `subnet_mask`
|
||||
- `gateway`
|
||||
- `dns`
|
||||
- `wlan_ssid`
|
||||
- `wlan_pwd`
|
||||
- `wlan_security`
|
||||
5. Change IP address in `s_target_address` variable to IP address of host running restful_server
|
||||
6. Uncomment line `#include <Adafruit_CC3000.h>`
|
||||
8. Compile and flash sketch
|
||||
9. restful_server will start to show current uptime and free memory size (with 5 seconds interval)

# Arduino Restful Server
|
||||
|
||||
This example demonstrates how to use [Mongoose](https://www.cesanta.com/mongoose) to control Arduino
|
||||
using HTTP requests.
|
||||
Example just blinks by LED when Mongoose receives HTTP command, but it can be modified to execute any user-specific code.
|
||||
|
||||
At the moment this example supports [Arduino Mega 2560](http://arduino.cc/en/Main/ArduinoBoardMega2560) board (and compatible) with either W5100-based
|
||||
network shield (like [Arduino Ethernet Shield](http://arduino.cc/en/Main/ArduinoEthernetShield)) or [CC3000](http://www.ti.com/product/cc3000)-based WIFI Shield.

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.
|
||||
|
||||
|
||||
