\r
30 * NOTE 1: This project provides two demo applications. A simple blinky style
\r
31 * project, and a more comprehensive test and demo application that makes use of
\r
32 * the FreeRTOS+CLI, FreeRTOS+UDP and FreeRTOS+FAT SL components. The
\r
33 * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting in main.c is used to select
\r
34 * between the two. See the notes on using mainCREATE_SIMPLE_BLINKY_DEMO_ONLY
\r
35 * in main.c. This file implements the comprehensive test and demo version,
\r
36 * which is fully documented on the following URL:
\r
37 * http://www.FreeRTOS.org/Atmel_SAM4E_RTOS_Demo.html
\r
39 * NOTE 2: This file only contains the source code that is specific to the
\r
40 * full demo. Generic functions, such FreeRTOS hook functions, and functions
\r
41 * required to configure the hardware, are defined in main.c.
\r
42 ******************************************************************************
\r
44 * Full user instructions are provided on the following URL:
\r
45 * http://www.FreeRTOS.org/Atmel_SAM4E_RTOS_Demo.html
\r
48 * + Uses FreeRTOS+FAT SL to create a set of example files on a RAM disk.
\r
49 * + Displays some bitmaps on the LCD.
\r
50 * + Registers sample generic, file system related and UDP related commands
\r
51 * with FreeRTOS+CLI.
\r
52 * + Creates all the standard demo application tasks and software timers.
\r
53 * + Starts the scheduler.
\r
55 * A UDP command server and optionally two UDP echo client tasks are created
\r
56 * from the network event hook after an IP address has been obtained. The IP
\r
57 * address is displayed on the LCD.
\r
59 * A "check software timer" is created to provide visual feedback of the system
\r
60 * status. The timer's period is initially set to three seconds. The callback
\r
61 * function associated with the timer checks all the standard demo tasks are not
\r
62 * only still executed, but are executing without reporting any errors. If the
\r
63 * timer discovers a task has either stalled, or reported an error, then it
\r
64 * changes its own period from the initial three seconds, to just 200ms. The
\r
65 * check software timer also toggles the LED marked D4 - so if the LED toggles
\r
66 * every three seconds then no potential errors have been found, and if the LED
\r
67 * toggles every 200ms then a potential error has been found in at least one
\r
70 * Information on accessing the CLI and file system, and using the UDP echo
\r
71 * tasks is provided on http://www.FreeRTOS.org/Atmel_SAM4E_RTOS_Demo.html
