[vc_row][vc_column width=”1/1″][vc_tour][vc_tab title=”Install” tab_id=”1389239567-1-92″][vc_column_text]Cloud9 IDE (http://www.c9.io) is an online development environment for Javascript and Node.js applications as well as HTML, CSS, PHP, Java, Ruby and 23 other languages.

We recommend that Cloud 9 IDE run on a SD card with capacity larger than 4GB. Please refer to chapter 2 on how to migrate program/data from NAND to a SD card.

Install required packages

$ sudo apt-get install git libssl-dev python-software-properties

Build nodejs ( required by cloud9 IDE )

$ git clone git://github.com/joyent/node.git

$ cd node

$ git checkout v0.8.22

$ make

$ sudo make install

After nodejs installed, you can delete the source to save space.

Build cloud9 IDE

$ git clone https://github.com/ajaxorg/cloud9.git

$ cd cloud9/

$ npm install

[/vc_column_text][/vc_tab][vc_tab title=”Run cloud9 on pcDuino” tab_id=”1389239567-2-22″][vc_column_text]$ ./bin/cloud9.sh -l 0.0.0.0

If you are going to run on pcDuino, use the Chrome browser on pcDuino, and point to http://127.0.0.1:3131.

If you are going to run on a PC or other device, use the Chrome browser on pcDuino, and point to http://board-ip-address:3131. The ip address of pcDuino can be found by using:

$ ifconfig

It’s very easy to run js code from cloud9.

Just write the code ( example blink_led.js ), then press button “RUN” on menu bar.

Run on pcDuino:

Run on PC:

The following is the example code:

blink_led.js:

/**

* blink_led.js, simple node.js test code for pcduino (http://www.pcduino.com)

* base on the source code from https://github.com/jheising/node.pcduino.git

*/

var fs = require(‘fs’);

var led_pin;

var INPUT = 0;

var OUTPUT = 1;

var LOW = 0;

var HIGH = 1;

function digitalWrite(pin, value)

{

fs.writeFileSync(“/sys/devices/virtual/misc/gpio/mode/gpio” + pin, String(value));

}

function pinMode(pin, mode)

{

fs.writeFileSync(“/sys/devices/virtual/misc/gpio/mode/gpio” + pin, String(mode));

}

function delay(ms)

{

var start = new Date().getTime();

for (var i = 0; i < 1e7; i++)

 if ((new Date().getTime() – start) > ms) break;

}

function setup()

{

led_pin = 18;

pinMode(led_pin, OUTPUT);

}

function loop()

{

digitalWrite(led_pin, HIGH);

delay(1000);

digitalWrite(led_pin, LOW);

delay(1000);

}

function main()

{

setup();

while(1)

{

loop();

}

}

main();

[/vc_column_text][/vc_tab][vc_tab title=”Run C/C++ program on cloud9 IDE” tab_id=”1389243534234-3-10″][vc_column_text]

Running C/C++ is almost the same as running a program from terminal.

Write your code first (example 00.pcDuino/blink_led.c ).

Run the following commands from command input box (at the bottom of cloud9 IDE):

cd 00.pcDuino/

g++ blink_led.c -larduino -I/usr/include/pcduino -o blink_led

./blink_led

The following is the example code:

blink_led.c

#include

int led_pin=18;

void setup()

{

pinMode(led_pin, OUTPUT);

}

void loop()

{

digitalWrite(led_pin, HIGH);

delay(100);

digitalWrite(led_pin, LOW);

delay(100);

}
