Getting Started with Arduino 101

To start programming the Arduino 101 (Intel® Curie™) embedded microcontroller of the UDOO X86 you need the Arduino IDE or the Arduino Web IDE.

You can refer the Getting Started with the Arduino/Genuino 101 page of the Arduino website.
This Arduino page will guide you through the installation of the IDE and the core board manager of the Arduino 101 other than everything you need to program the Arduino and use the pinout.

Linux known issues

Installation

In some previous Arduino IDE version there was some installation issues, but now you can download the latest Arduino IDE version (at least Arduino IDE 1.8.3) and you should not find any Linux installation issue.
Heads up! Remember to always keep updated you Arduino IDE installation.
Check the page Install the Arduino Software (IDE) on Linux to have useful advice about the Linux installation.

Upload Procedure

Some Linux distributions need to be configured to gain upload permissions to the user.
Usually you can do it with the command:

sudo usermod -a -G dialout <username>

Check the page Install the Arduino Software (IDE) on Linux to find more info about it.
Inside the Arduino 101 core you can find a script to allow the user to use the serial device. Using the latest Arduino 101 core package v2.0.4 run the script with this commands:

chmod +x ~/.arduino15/packages/Intel/hardware/arc32/2.0.4/scripts/create_dfu_udev_rule
sudo ~/.arduino15/packages/Intel/hardware/arc32/2.0.4/scripts/create_dfu_udev_rule

USB Devices

The USB device where you can find the Arduino 101 (Intel® Curie™) embedded may vary in accordance with the number of USB devices connected to the board.
Usually, you should find the Arduino 101 in the COM3 in Windows 10 and /dev/ttyACM0 in Unix/Linux OS.
