This demonstration shows a bubble level implementation based on a digital accelerometer. We use
I
2
C protocol to control the ADXL345 digital accelerometer, and the APDS-9300 Miniature Ambient
Light Photo Sensor. The LCD displays the interface of our game. When tilting the
VEEK-MT-SoCKit, the ADXL345 measures the static acceleration of gravity. In our Nios II
software, we compute the change of angle in the x-axis and y-axis, and show the angle data on the
LCD display. The value of light sensor will change as the brightness changes around the
light-sensor.
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 and other components. Tere is also a 40MHz clock generated for
low-speed peripherals.
