C your Arduino in different way

Articles about programming Arduino with pure C.

• Arduino in C
• Program Arduino with AVR-GCC
• Programming Arduino Uno in pure C

Good tool for building Arduino in  command-line mode.

• Ino

ps. Arduino build process

Good articles about Arduino and IMU

Kalman filter is the one of the filter, or signal processing technique that lures me.

I wanna make a small system (via Arduino) to implement it and act as the lab material of embedded system tutorial.

Some useful websites and source code listing here :

• Arduino 5 min tutorial -- IMU 
• A practical approach to Kalman filter and how to implement it
• TKJ Eelectronics's Github

Besides, here is the Arduino PID lib.

Great article : Faster analogRead()
