freertos_mutex
Keil Studio AC6, GCC, IARThis document explains the freertos_mutex example. It shows how mutex manage access to commonresource (terminal output).The example application creates two identical instances of write_task. Each task will lock the mutexbefore printing and unlock it after printing to ensure that the outputs from tasks are not mixedtogether.The test_task accept output message during creation as function parameter. Output message have twoparts. If xMutex is unlocked, the write_task_1 acquire xMutex and print first part of message. Thenrescheduling is performed. In this moment scheduler check if some other task could run, but secondtask write_task+_2 is blocked because xMutex is already locked by first write task. The firstwrite_task_1 continue from last point by printing of second message part. Finaly the xMutex isunlocked and second instance of write_task_2 is executed.

freertos_queue
µVision AC6This document explains the freertos_queue example. This example introduce simple logging mechanismbased on message passing.Example could be devided in two parts. First part is logger. It contain three tasks:log_add().....Add new message into the log. Call xQueueSend function to pass new message into message queue.log_init()....Initialize logger (create logging task and message queue log_queue).log_task()....Task responsible for printing of log output.Second part is application of this simple logging mechanism. Each of two tasks write_task_1 andwrite_task_2 print 5 messages into log.

freertos_sem
µVision AC6This document explains the freertos_sem example, what to expect when running it and a briefintroduction to the API. The freertos_sem example code shows how semaphores works. Two differenttasks are synchronized in bilateral rendezvous model.The example uses four tasks. One producer_task and three consumer_tasks. The producer_task starts bycreating of two semaphores (xSemaphore_producer and xSemaphore_consumer). These semaphores controlaccess to virtual item. The synchronization is based on bilateral rendezvous pattern. Both ofconsumer and producer must be prepared to enable transaction.
