7.5 LED Matrix Driver and Snake Game Algorithm
All the LEDs on the QT2 Xplained Pro board are driven by the LED Matrix
driver (IS31FL3728), which is controlled by the I2C. For detailed
instructions on how to interface the LED matrix driver, refer to the driver device data
sheet at http://www.issi.com/. A suitable I2C-based driver is implemented
for the snake game demo. The led driver related code routines are available in the
LEDdriver.c file.
A modular code is written for the snake game algorithm to demonstrate the
capabilities of the touch surface. The snake algorithm related code routines are
available in the Snake.c file. Figure 7-3 depicts the application flow for the
snake game algorithm.
