FreeRTOS Example (freertos_demo)

+//! +//! This application demonstrates the use of FreeRTOS on Launchpad. +//! +//! The application blinks the user-selected LED at a user-selected frequency. +//! To select the LED press the left button and to select the frequency press +//! the right button. The UART outputs the application status at 115,200 baud, +//! 8-n-1 mode. +//! +//! This application utilizes FreeRTOS to perform the tasks in a concurrent +//! fashion. The following tasks are created: +//! +//! - An LED task, which blinks the user-selected on-board LED at a +//! user-selected rate (changed via the buttons). +//! +//! - A Switch task, which monitors the buttons pressed and passes the +//! information to LED task. +//! +//! In addition to the tasks, this application also uses the following FreeRTOS +//! resources: +//! +//! - A Queue to enable information transfer between tasks. +//! +//! - A Semaphore to guard the resource, UART, from access by multiple tasks at +//! the same time. +//! +//! - A non-blocking FreeRTOS Delay to put the tasks in blocked state when they +//! have nothing to do. +//! +//! For additional details on FreeRTOS, refer to the FreeRTOS web page at: +//! http://www.freertos.org/ +// +//***************************************************************************** + + +//***************************************************************************** +// +// The mutex that protects concurrent access of UART from multiple tasks. +// +//***************************************************************************** +xSemaphoreHandle g_pUARTSemaphore; + +//***************************************************************************** +// +// The error routine that is called if the driver library encounters an error. +// +//***************************************************************************** +#ifdef DEBUG +void +__error__(char *pcFilename, unsigned long ulLine) +{ +} + +#endif + +//***************************************************************************** +// +// This hook is called by FreeRTOS when an stack overflow error is detected. +// +//***************************************************************************** +void +vApplicationStackOverflowHook(xTaskHandle *pxTask, signed char *pcTaskName) +{ + // + // This function can not return, so loop forever.
