### Hummingbird-based TFT screen display experiment

**Project name：**Hummingbird-based TFT screen display experiment

**Specific requirements：**displaying a specified image on a TFT screen

TFT screen introduction：

This experiment uses a 3.5-inch TFT-LCD, model QD3503728. QD353728 is a color active-matrix liquid crystal module containing amorphous silicon TFT (thin film transistor). It consists of color TFT-LCD panel, driver IC, FPC and backlight unit, the display area of this module contains 320x480 pixels.

- Specific requirements：Display the specified content through Hummingbird TFT screen.

- Experimental process：

1、 Open the configured virtual machine, copy the .c, .h and Makefle files in the TFT folder to the directory in the above experiment: /home/a/desktop/1/sirv-e-sdk/software/demo_gpio

2、 connect the JTAG downloader and the computer, the JTAG downloader and the development board, and plug the screen into the development board, as shown below.
