This code is written for a demo application that displays a color palette on a TFT LCD screen and allows the user to select colors by touching the screen. The code initializes the necessary hardware components, including the FSMC TFT interface and the LCD display. It also includes functions for drawing points and filling colors on the screen. The main function of the code continuously scans for touch events using the GT9147 touchscreen controller. When a touch event is detected, the drawbigpoint function is called to draw a 2x2 pixel point on the screen at the location of the touch event. If the touch event corresponds to the "CLR" button on the screen, the FillColor function is called to clear the screen. If the touch event corresponds to one of the color blocks on the screen, the POINT_COLOR variable is set to the corresponding color. Overall, this code provides a simple demonstration of how to use a touchscreen controller to interact with a TFT LCD screen.
