A simple blinky style project, * and a more comprehensive test and demo application. The * configCREATE_SIMPLE_TICKLESS_DEMO setting (defined in FreeRTOSConfig.h) is * used to select between the two. The simply blinky demo is implemented and * described in main_blinky.c. The more comprehensive test and demo application * is implemented and described in main_full.c. * * The comprehensive demo uses FreeRTOS+CLI to create a simple command line * interface through a UART. * * The blinky demo uses FreeRTOS's tickless idle mode to reduce power * consumption. See the notes on the web page below regarding the difference * in power saving that can be achieved between using the generic tickless * implementation (as used by the blinky demo) and a tickless implementation * that is tailored specifically to the MSP432. * * This file implements the code that is not demo specific. * * See http://www.FreeRTOS.org/TI_MSP432_Free_RTOS_Demo.html for instructions. * */ /* Standard includes. */ #include /* Kernel includes. */ #include "FreeRTOS.h" #include "task.h" /*-----------------------------------------------------------*/ /* * Set up the hardware ready to run this demo. */ static void prvSetupHardware( void ); /* * main_blinky() is used when configCREATE_SIMPLE_TICKLESS_DEMO is set to 1. * main_full() is used when configCREATE_SIMPLE_TICKLESS_DEMO is set to 0. */ extern void main_blinky( void ); extern void main_full( void ); /*-----------------------------------------------------------*/ int main( void ) { /* See http://www.FreeRTOS.org/TI_MSP432_Free_RTOS_Demo.html for instructions. */ /* Prepare the hardware to run this demo. */ prvSetupHardware(); /* The configCREATE_SIMPLE_TICKLESS_DEMO setting is described at the top of this file. */ #if configCREATE_SIMPLE_TICKLESS_DEMO == 1 { main_blinky(); } #else { main_full(); } #endif return 0; } /*-----------------------------------------------------------*/ static void prvSetupHardware( void ) { extern void FPU_enableModule( void ); /* The clocks are not configured here, but inside main_full() and main_blinky() as the full demo uses a fast clock and the blinky demo uses a slow clock. */ /* Stop the watchdog timer. */ MAP_WDT_A_holdTimer(); /* Ensure the FPU is enabled. */ FPU_enableModule(); /* Selecting P1.2 and P1.3 in UART mode and P1.0 as output (LED) */ MAP_GPIO_setAsPeripheralModuleFunctionInputPin( GPIO_PORT_P1, GPIO_PIN2 | GPIO_PIN3, GPIO_PRIMARY_MODULE_FUNCTION ); MAP_GPIO_setOutputLowOnPin( GPIO_PORT_P1, GPIO_PIN0 ); MAP_GPIO_setAsOutputPin( GPIO_PORT_P1, GPIO_PIN0 ); } /*-----------------------------------------------------------*/ void vApplicationMallocFailedHook( void ) { /* vApplicationMallocFailedHook() will only be called if configUSE_MALLOC_FAILED_HOOK is set to 1 in FreeRTOSConfig.h.
