* 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
|
|
* 2. Buils and run in console /Users/alex/Projects/mongoose/examples/restful_server example
|
|
* 3. Make board_ip and board_mac variables suitable for your network and board
|
|
* 4. Uncomment line #include <Ethernet.h>
|
|
* 5. Change IP address in s_target_address variable to IP address of host running restful_server
|
|
* 6. Compile & flash sketch
|
|
* 7. restful_server server will start to show current uptime and free memory size (with 5 second 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 run 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. Uncomment line #include <Adafruit_CC3000.h>
|
|
* 6. Compile & flash sketch
|
|
* 7. restful_server server will start to show current uptime and free memory size (with 5 second interval) *
