SGWEB

SGWEB is a PHP/JS framework that let you control the A9 and arduino pins of your UDOO NEO.

Requirements

• UDOO NEO with UDOObuntu (version used v2.0 rc1)

• PHP capable web server

• JQuery v2.2.0

• Python

Version

Initial release

Installation

You need to set up a web server (like lamp):

$ sudo apt-get install tasksel
$ sudo apt-get install lamp-server^

You then need to change the default apache2 port from 80 to another (by editing /etc/apache2/ports.conf ) or change the port of UDOO quick start.

Now you have to export GPIO (see docs) and give r/w permission on GPIO files (the files are /sys/class/gpio/gpioX/value and /sys/class/gpio/gpioX/direction , where X is pin number) and on serial port (/dev/ttyMCC ), or simply use the provided bash script.

If you are not planning to use Arduino pins, you are ready to begin.

To use the arduino pinout you must use the the sketch sgweb.ino and the python script sgweb.py

USAGE

Simply include the PHP and JS (if needed in your project files).

You can:

• Set pin as in or out

• Write 1/0 on pin

• Read value on pin (see docs for more informations)

• Set PWM

• Read analog value (arduino only)

• Read i2c values

See examples and files comments for more infos.

To use i2c brick sensors you need to enable them (for the one in the example, TMP75b, run sudo sh -c 'echo lm75 0x48 > /sys/class/i2c-dev/i2c-1/device/new_device' )

KNOWN ISSUES

Regarding the arduino side, if you set a pin as output (using pinMode ) you can't use it as PWM (see here).
