Scenario:

example 1 ,to Linux greet

From Arduino compatible IDE Detect IP :

This example is Arduin versus Yun Extended communication test board. Available in the Arduino compatible IDE File Example bridge ConsoleRead turn up. Instructions can be found in the example Here turn up. The following codes are listed and described in detail in order to understand Yun Expansion boards.

example 2 To upload data networking server

This example shows how to record data to a common networking server Xively in. The modified examples can make Console Serial adapt to different Arduino compatible board. in Ardui IDE File Example bridge XivelyClient You can be found, Here You can see a detailed explanation.

Before you download the ject, ensure that: Yun Expansion board has access to the Internet.

Reference instruction manual input FEEDID and APIKEY , Pay attention to FEEDID Write in double quotes.

The serial class to class to suit different independent AVR .

example 3 ,use U Disc recording data

This example shows how to use U Disc recording data. Engineering and to use this example U Disc recording data the same. Source code Here . Yun Expansion board will automatically create a directory / Mnt / sda1 . ject sensor data will be saved as file / mnt / sda1 / data / datalog.csv . So make sure before using engineering U There is such a disk file.
