Basic LCD Project 1.4

Purpose

This application displays two preloaded images on the board LCD, alternating between each image every other second.

Description

When launched, this example will start displaying two images alternatively, changing between them every two seconds. The images must be loaded in SDRAM before the program execution, at offsets 0x100000 and 0x200000, respectively.

The image files must only contain raw RGB data, as no file format conversion is done. Two already processed images, named image1 and image2, are provided in the project folder.

Usage

1. Compile the application.
2. Using SAM-BA, enable the SDRAM of the chip and download the two images provided, at offsets 0x100000 and 0x200000, respectively. Please refer to the SAM-BA User Guide for more information about that step.
3. Optionally, connect the DBGU port of the evaluation board to the computer and open it in a terminal. Debug information generated by the application will be visibled that way.
• Settings: 115200 bauds, 8 bits, 1 stop bit, no parity, no flow control.
4. Using SAM-BA, download the program inside the evaluation board and run it.
5. The two downloaded images should appear alternatively on the LCD. In addition, the following message should appear on the DBGU:
