Learning Examples | Foundations | Hacking | Links Overview A number of things have to happen for your Arduino code to get onto the Arduino board. First, the Arduino environment performs some small transformations to make sure that the code is correct C or C++ (two common programming languages). It then gets passed to a compiler (avr-gcc), which turns the human readable code into machine readable instructions (or object files).

Then, your code gets combined with (linked against), the standard Arduino libraries that provide basic functions like digitalWrite() or Serial.print(). Multi-file sketches A sketch can contain multiple files (tabs). Transformations to the main sketch file The Arduino environment performs a few transformations to your main sketch file (the concatenation of all the tabs in the sketch without extensions) before passing it to the avr-gcc compiler. First, #include "Arduino.h", or for versions less than 1.0, #include "WProgram.h" is added to the top of your sketch.

Targets. Wiki:lininoonearduinoide [] OPKG Package Manager. The opkg utility (an ipkg fork) is a lightweight package manager used to download and install OpenWrt packages from local package repositories or ones located in the Internet. GNU/Linux users already familiar with apt-get, aptitude, pacman, yum, etc. will recognize the similarities. It also has similarities with NSLU2's Optware, also made for embedded devices. OPKG is however a full package manager for the root file system, instead of just a way to add software to a seperate directory (e.g.

/opt). Opkg attempts to resolve dependencies with packages in the repositories - if this fails, it will report an error, and abort the installation of that package. Missing dependencies with third-party packages are probably available from the source of the package. Please note: If you are using Barrier Breaker (bleeding edge version), opkg install <pkg> may fail, if the package in the repository is for a newer kernel version then the kernel version on your flash. Invocation Package Manipulation Options. YunPackageManager. Learning Examples | Foundations | Hacking | Links The package management system, also called “package manager”, is a very important tool for Linux systems as it gives the user an easy way to install, update and remove additional applications or programs. Instead of downloading and compiling the source code of the program you want to install, the source is pre-configured and compiled according to your system requirements and is inserted inside a package with other information, such as the version and dependencies (requirements of the software to install the software).

On the OpenWrt-Yun Linux system the package manager tool is called “opkg”. Usually operations on a package can be done through the command line with a few arguments. The package manager needs an updated database to display packages available for your system. The most important arguments for opkg are: update : Updates the package database. Example:$ opkg update install: Installs a package.

Example:$ opkg install fortune-mod. Process. Learning Examples | Foundations | Hacking | Links Examples > Process Process This example for the Arduino Yún shows how to use the Bridge library's Process class to run Linux processes on the AR9331. Specifically, in this example, you'll be using curl and cat to transfer data from a web server and get information on the Linux processor.

Hardware Required Arduino Yún a network connection to the internet Circuit There is no circuit for this example. Code Include the Process class in your sketch. In setup(), you'll want to initialize Bridge and start a serial connection. Voidsetup(){ Bridge.begin();Serial.begin(9600); while (! The rest of setup() is used to call your two custom functions, runCurl() and runCpuInfo().

RunCurl(); runCpuInfo();} void loop() { // Do nothing here.} runCurl() will launch the curl command and download the Arduino logo as ASCII. Void runCurl() { Process p; p.begin("curl"); p.addParameter("; The full code is below : ShellCommands. Learning Examples | Foundations | Hacking | Links Examples > ShellCommands Shell Commands This sketch demonstrates running Linux shell commands on an Arduino Yún.

It runs the wifiCheck script (located at /usr/bin/pretty-wifi-info.lua) on the Linux processor, then uses grep to get the signal strength. On the 32U4, parseInt() is called to read the WiFi signal strength as an integer, and uses that number to fade an LED with analogWrite().

Intel Centrino Advanced-N 6235 Wi-Fi / Bluetooth 6235AN.HMWWB. BoardYun. (redirected from Products.ArduinoYUN) Overview The Arduino Yún is a microcontroller board based on the ATmega32u4 (datasheet) and the Atheros AR9331. The Atheros processor supports a Linux distribution based on OpenWrt named OpenWrt-Yun. The board has built-in Ethernet and WiFi support, a USB-A port, micro-SD card slot, 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a 3 reset buttons. NB : In some countries, it is prohibited to sell WiFi enabled devices without government approval.

The Yún distinguishes itself from other Arduino boards in that it can communicate with the Linux distribution onboard, offering a powerful networked computer with the ease of Arduino. The Yún is similar to the Leonardo in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. Summary Schematic & Reference Design Power The power pins are as follows: Arduino Yun - USB Battery Pack for Net-Aware Robot Project. I apologize, in advance, if this information is contained here somewhere or on other Arduino sites.

I did as may google/forums searches as I could think of and was not able to find a complete answer... Knowing that the Yun needs 5v and connecting anything above that can lead to a fried Yun, I was looking for a battery pack solution. How important is amperage output for the Yun? Can you fry it at 1-2A or do I only need to worry about voltage?

I want to use the Yun and a decent external source to power a net-aware, wi-fi based remote controllable, and avoidance AI robot project I am building. The ideal battery pack would power some additional devices through the Yun's 5v out pin (ping sensor, motor shield, two motors, a few servos, maybe a few other sensors). Any other suggestions? Thanks in advance! -Jerry. Yun with batteries. I have just tested a setup based on Arduino Yun. This is what I'v learned so far (I'm still testing): My setup include a voltage regulator based on this example (LM317): 1) 9V Alkaline Battery -> LM317 regulator -> 5V to arduino vin pinArduino Yun is completely unstable. It hangs with led 13 flashing for a while, then stop working after some seconds. 2) 4 Alkaline AA Battery (6V) -> LM317 regulator -> 5V to arduino vin pinArduino yun work for some seconds, but as soon as you stress it by accessing web pages on the httpd and the SD card, the SD card itself became unstable and fail to serve some files. 3) 7.2V from external power source (8-900 mA) -> LM317 regulator -> 5V to arduino vin pinArduino works like a charm, serving web pages, talking via I2C with another arduino and acting as remote control for a robot.

In all these setup I'v read the voltage output from the regulator and it was stable at 5V. Securitate - Setări cont. Installing Ubuntu inside Windows using VirtualBox.

Need help on Linux I2C driver. Gcc tutorial. Gcc is the "GNU" C Compiler, and g++ is the "GNU C++ compiler, while cc and CC are the Sun C and C++ compilers also available on Sun workstations. Below are several examples that show how to use g++ to compile C++ programs, although much of the information applies to C programs as well as compiling with the other compilers. Example 1: Compiling a simple program Consider the following example: Let "hello.C" be a file that contains the following C++ code. #include "iostream.h" int main() { cout << "Hello\n"; } The standard way to compile this program is with the command g++ hello.C -o hello This command compiles hello.C into an executable program named "hello" that you run by typing 'hello' at the command line.

Alternatively, the above program could be compiled using the following two commands. g++ -c hello.C g++ hello.o -o hello Frequently used compilation options Compile myprog.C so that myprog contains symbolic information that enables it to be debugged with the gdb debugger.
