+In this project I attempted to create a backup avionics device ("Artificial horizon") based on a microcontroller (Freedom board FRDM-KL46Z), a Motion Trackig device that combines a 3-axis gyroscope, 3-axis accelerometer, and a Digital Motion Processor™ (InvenSense MPU-6050), and a simple 1.8-inches LCD monitor with SPI interface. 
+The code is written in C. 
+The raw data has been read from MPU-6050 through I2C interface, processed with complementary filter, and then displayed on an LCD through SPI interface. The GUI of the project imitates the behavior of a real "Artificial horizon" device with respect to the roll and pitch angles of an aircraft.

+Used libraries and brief description:
+MMA8451Q - used for communication with the on-board accelerometer (on FRDM-KL46Z)
+MPU6050, MPU6050RegDef - used for communication with the MPU-6050 board
+ST7735, GraphicsDisplay, TextDisplay - used for comminication with the LCD
+
+More information on libraries can be found on mbed.org. I'm very grateful to all people who contributed to the development of these libraries and shared them to the public.
