Digital Accelerometer Demonstration
This demonstration shows a bubble level implementation based on a digital accelerometer. There are
two I2C controllers used in this demonstration. One is used to communicate with MPU9250 to retrieve
the gravity information, and another is used to communicate with the APDS-9300 Miniature Ambient
Light Photo Sensor. The demonstration using the gravity information retrieved from the MPU9250 to
implement a bubble level on the LCD panel. When tilting the VEEK-MT2, the NIOS II program reads
the acceleration of gravity from the MPU9250. Based on the gravity information, the NIOS II program
can compute the change of angle in the x-axis and y-axis, and shows the angle data in the LCD display.
The demonstration also displays two ambient light levels, measured by APDS-9300, on the LCD panel.
shows the hardware system block diagram of this demonstration. The system is clocked by
an external 50MHz Oscillator. Through the internal PLL module, the generated 100MHz clock is used
for Nios II processor, SDRAM, SSRAM, and other high speed controllers. The PLL also generate a
