Most of the time, the RTOS stores the base address of the task stack in the task's control block (TCB). The other task is the Timer Service task which is what enables me to use the software delay (vTaskDelay). If you have more FreeRTOS PSoC Examples that you are interested in please make a comment and maybe Ill create them. Each task requires RAM that is used to hold the task state, and used by the task as its stack. Proper state machine architecture for TI-RTOS. Alternatively the task handle is returned from the call to xTaskCreate(). The CoRTOS module compiles to. However, how to analyse and design a RTOS-based project is not part of the workshop and thus requires another course. For example, FreeRTOS will add approximately 60 bytes to the stack on a Cortex-M - which is used to store the task's context when the task is not running. TI Drivers examples) point to the kernel project. The use of a Real-Time Operating System (RTOS) is increasingly common in embedded software designs.
