29 * This project provides two demo applications. A simple blinky style project,
\r
30 * and a more comprehensive test and demo application. The
\r
31 * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting (defined in this file) is used to
\r
32 * select between the two. The simply blinky demo is implemented and described
\r
33 * in main_blinky.c. The more comprehensive test and demo application is
\r
34 * implemented and described in main_full.c.
\r
36 * This file implements the code that is not demo specific, including the
\r
37 * hardware setup and FreeRTOS hook functions.

114 heap available to pvPortMalloc() is defined by configTOTAL_HEAP_SIZE in
\r
115 FreeRTOSConfig.h, and the xPortGetFreeHeapSize() API function can be used

116 to query the size of free heap space that remains (although it does not

128 to block in any way (for example, call xQueueReceive() with a block time

130 vTaskDelete() API function (as this demo application does) then it is also
\r
131 important that vApplicationIdleHook() is permitted to return to its calling
