The Udoo-Neo Host program is a multi-threaded C program that's run in the Linux side of the Udoo-Neo and shall provide a bridge to services and applications running in Linux to be accessed by the M4 Arduino side of the Neo. This project is inspired by Udoo-Library project by David Smerkous's Udoo Library.

The goals of this project are:

1. Udoo Neo specific (David's library did not work correctly on Neo)
2. Use C programming language
3. Multi-threaded
4. Low footprint
5. Memory efficient code
6. Fast code

While the project's intention is to develop a platform of services to the Arduino side, the current scope of the project is to provide the following services to the Arduino:

• Log - Implement a file log of timestamped messages
• Debug - Implement a "terminal-like" interface to display messages sent by the Arduino
• Email - Send an email with the address, subject and message provided by the Arduino. Also, be able to add attachments to email.
• Shell - Invoke a shell command on the Linux side
• Database - Store values on persistent storage (database)
• Webcam - Access the webcam for taking a picture
