&par Example Description

The program aims to show how to use interrupt to get LCD touch chip data by using I2C, in this case,
I2C continuously get the data of the touch chip through interrupt and convert it to axis lable data
in the window of LCD(4.3 inch and 800 x 480 pixe).

You can touch some button to get control led and get some information in the LCD.
Each time a complete touch data is got , LED1 will be toggle.
