esp8266

Based on the nice instruction, now I have to try ITO with the little module esp8266.

• In this this experiment I follow the esp8266 repository. As the preparation below, 
• Install Arduino 1.6.5 or higher from the Arduino website. 
• Start Arduino and open Preferences window. 
• Enter http://arduino.esp8266.com/stable/package_esp8266com_index.json into Additional Board Manager URLs field. 
• You can add multiple URLs, separating them with commas. 
• Open Boards Manager from Tools > Board menu and install esp8266 platform (and don't forget to select your ESP8266 board from Tools > Board menu after installation).

#include <ESP8266WiFi.h>

const char* ssid     = "networkID";//enter your network ssid

const char* password = "password"; //password of the network

void setup(){

    Serial.begin(115200);   //an esp8266 uses 115200 bit rate by default 

    delay(100);             //some small delay the get the serial connection ready 

    

    //attempting to connect the network and aquiring IP from a DHCP server

    Serial.print("Connecting to netwok");

    Serial.println(ssid);

    WiFi.begin(ssid, password);

    

    //waiting for connection

    while (WiFi.status() != WL_CONNECTED){

            delay(500);

            Serial.print(".");

    }

    //show connection details

    Serial.println("Connected IP address: ");   

    Serial.println(WiFi.localIP());

}

Enabling OMP on PC

In cs426, we use OpenMP both on PC and in SciCloud. If you want to try OpenMP on you laptop or PC, you may have to install some software as following.

1. get CodeBlock IDE and MinGW
2. include C:\MinGW\bin to system path
3. install mingw32-pthreads-w32 using C:\MinGW\bin\mingw-get.exe
4. In codeBlock, Settings>>compiler>>linker setting>>link library=C:\MinGW\bin\libgomp-1.dll
5. In codeBlock, Settings>>compiler>>compiler settings>>other options= -fopenmp

You may need to restart your computer to apply the new configuration.
