The VEEK-MT-SoCKit features a 7-inch capacitive amorphous TFT-LCD panel. The LCD touch
screen offers resolution of 800x480 to provide users the best display quality for developing
applications. The LCD panel supports 24-bit parallel RGB data interface.
The VEEK-MT-SoCKit is also equipped with a Touch controller, which can read the coordinates of
the touch points through the serial port interface of the Touch controller.
To display images on the LCD panel correctly, the RGB color data along with the data enable and
clock signals must act according to the timing specification of the LCD touch panel, as shown in
Table 3-1. Table 3-2 gives the pin assignment information of the LCD touch panel.
